Introduction  
The Intel Advanced/ZP baseboard features the Pentiumâ processor in a Baby-AT form factor with integrated I/O.  
Advanced/ZP baseboards are focused on providing the best possible performance at the lowest possible price for mainstream  
desktop computers.  
Advanced/ZP is a flexible baseboard which is available with the 75 MHz, 90 MHz, 100 MHz, or 120 MHz Pentium processor.  
The processor is complemented by a standard 256 KB asynchronous SRAM second level write-back cache and support for up  
to 128 MB of Fast Page or EDO DRAM. A Pentium OverDriveÒ socket (Socket 5) provides access to future performance  
enhancements.  
The Advanced/ZP baseboard offers outstanding I/O capabilities starting with the full set of I/O, including a floppy drive  
interface, dual channel PCI local bus IDE interfaces, two serial ports with FIFOs, an EPP/ECP capable parallel port, and an  
infrared (IrDA) port. Two dedicated PCI local bus slots, and one shared PCI/ISA slot, provide a high bandwidth data path for  
functions such as graphics that have a high data throughput requirement. The integrated Bus Mastering capable PCI IDE  
controller provides two high performance IDE interfaces for hard drives and CD-ROMs. Bus mastering enhances the  
performance in multi-tasking environments such as Windows* 95. The Advanced/ZP baseboard also provides three dedicated  
ISA connectors and one shared PCI/ISA connector. There is one PCI full length capable slot, and three ISA full length  
capable slots.  
In addition to superior hardware capabilities, features like Windows 95-ready Plug and Play and Advanced Power  
Management (APM) with application restart are provided by software available from Intel for the Advanced/ZP platform.  
The Advanced/ZP baseboard provides the foundation for cost effective, high performance, highly expandable platforms which  
deliver the latest in CPU and I/O technology.  
Although the Advanced/ZP will support CGA emulation by VGA cards, it will not support CGA cards.  
ADVANCED/ZP FORM FACTOR  
The Advanced/ZP baseboard is designed to fit into a standard Baby-AT form factor chassis. Figure 1 illustrates the  
mechanical form factor for the Advanced/ZP. The actual dimensions of the Advanced/ZP baseboard do not strictly adhere to  
the standard Baby-AT guidelines, and exceptions to the standard are listed in the Baseboard Design Exceptions section.

BASEBOARD DESIGN EXCEPTIONS  
BASEBOARD DIMENSIONS  
The Advanced/ZP is 3.0" shorter than the Baby-AT standard. The shorter board length may require some chassis to be  
modified to add additional mounting holes.  
MOUNTING HOLE PLACEMENT  
The mounting holes located in the bottom left and right corners of Figure 1 are pseudo Baby-AT standard and are  
available in many, but not all, Baby-AT compatible chassis.  
FRONT PANEL CONNECTORS  
There is no front panel connector on the baseboard for a Turbo/Deturbo switch. The processor speed can be set either  
through a parameter in the CMOS Setup Utility, or from the keyboard (<CTL><ALT><+> = Turbo, <CLT><ALT><-> =  
Deturbo). Changing processor speed from the keyboard may be prohibited by the operating system, or when the processor  
is in protected mode.  
Setting the processor to deturbo (or slow) only slows the processor to the approximate equivalent of a 25 MHz clock rate,  
not the standard 8 MHz clock rate.  
JUMPERS/SWITCHES  
There is no Color/Mono jumper/switch on the baseboard to specify Monochrome or Color video mode at boot, the BIOS  
will automatically detect the type of video card installed.  
Also, there is no Flash write protect jumper/switch, the BIOS needs to be able to write to FLASH to support the Plug and  
Play features.

Figure 2. Advanced/ZP Board Level Features  
CPU  
The Advanced/ZP baseboard is designed to operate with 3.3 volt Pentium processors. A patented on-board voltage regulator  
circuit provides the required 3.3 volts from the 5 volt tap provided by a standard PC power supply. The baseboard supports  
the Pentium processors at iCOMPä index 610 \ 75 MHz, 735 \ 90 Mhz, 815 \ 100 Mhz, and 1000 \ 120 Mhz. The Pentium  
processor is backward-compatible with the 8086, 80286, i386ä and i486ä CPUs. It supports both read and write burst mode  
bus cycles, and includes separate 8K on-chip code and data caches which employ a write-back policy. Also integrated into  
the Pentium processor is an advanced numeric coprocessor which significantly increases the speed of floating point  
operations, while maintaining backward compatibility with i486DX math coprocessor and complying to ANSI/IEEE  
standard 754-1985.  
All Advanced/ZP baseboards support the 75 MHz and 90 MHz processors. The matrix below shows which Printed Board  
Assemblies (PBA number found on the baseboard) also support the 100 MHz or 120 MHz processor.

PERFORMANCE UPGRADE  
A 320-pin Type 5 Zero Insertion Force socket provides users with a performance upgrade path to future, higher speed,  
Pentiumâ processors. An OverDrive processor being developed for use with this socket will provide performance beyond  
that delivered by the originally installed Pentium processor.  
SECOND LEVEL CACHE  
The Pentium processor's internal cache is complemented by 256 KB direct mapped write-back second level cache. The 256  
KB cache configuration is implemented with eight 32kx8 asynchronous SRAM devices for the cache data and one 32kx8  
SRAM for the cache tag. The cache size is set by three configuration jumpers located on the baseboard. This is preset by the  
factory to support the onboard 256 KB configuration.  
Advanced/ZP Technical Product Summary · Page 5  
 
SYSTEM MEMORY  
The Advanced/ZP baseboard provides four 72-pin SIMM sites for memory expansion. The sockets support 1M x 32 (4 MB),  
2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32 MB) single-sided or double-sided SIMM modules. Minimum memory  
size is 8 MB and maximum memory size, using four 8M x 32 SIMM modules, is 128 MB. For external CPU speeds of less  
than 60 Mhz (used with 75, 90 and 120 Mhz processors) memory timing requires 70 ns fast page devices or, for higher  
performance, 70 ns EDO DRAM. For external CPU speeds of 66 Mhz (used with 100 Mhz processors) you must use 60 nS  
EDO DRAM, but 70 nS fast page DRAM may still be used. Parity generation and checking is not supported by the chip set.  
The four sockets are arranged as Bank 0 and Bank 1, with each bank consisting of two sockets and providing a 64-bit wide  
data path. Both SIMMs in a bank must be of the same memory size and type, however Banks 0 and 1 may have different  
types of memory installed. It is even possible to have 70 ns Fast Page DRAM in one bank and 60 ns EDO DRAM in the  
other, in which case each bank is independently optimized for maximum performance. Bank 0 only, Bank 1 only, or both  
banks may be populated. There are no jumper settings required for the memory size or type, which is automatically detected  
by the system BIOS. Tin lead SIMMs are required to be used when adding Fast Page or EDO DRAM.  
EDO DRAM  
Extended Data Out (or Hyper Page Mode) DRAM is designed to improve the DRAM read performance. EDO DRAM  
holds the memory data valid until the next CAS# falling edge, unlike standard fast page mode DRAM which tri-states  
the memory data when CAS# negates to precharge for the next cycle. With EDO, the CAS# precharge overlaps the data  
valid time, allowing CAS# to negate earlier while still satisfying the memory data valid window time.  
EXPANSION SLOTS  
Up to six expansion slots may be populated on the Advanced/ZP baseboard. There are four ISA bus expansion conectors and  
three PCI expansion connectors. One slot is shared by connectors that will accommodate either an ISA or a PCI expansion  
card, but not both at the same time. This accounts for the disparity between the number of slots and connectors. All three  
PCI expansion slots accept PCI bus mastering cards, and fully comply with the PCI 2.10 specification. Three of the ISA  
slots and one PCI slot can accommodate full length add-in cards. Interference with the processor heat sink and CPU voltage  
regulator support circuitry limits the rest of the ISA and PCI slots to being able to support only half-length add-in cards.  
PCI 3.3 VOLT CAPABILITIES  
To maintain strict compliance with the PCI specification, the baseboard provides a connector which can be used to route  
3.3 volt power to the PCI slots. The connector may be used with a separate 3.3 volt power supply or with a custom  
designed voltage converter. Note: The on-board 3.3 volt regulator provides power for the CPU, PCIset and L2 cache  
only, not the PCI slots.

82437FX TRITON SYSTEM CONTROLLER (TSC)  
The 82437FX provides all control signals necessary to drive a second level cache and the DRAM array, including  
multiplexed address signals. It also controls system access to memory and generates snoop controls to maintain cache  
coherency. The TSC comes in a 208 pin QFP package.  
82438FX TRITON DATA PATH (TDP)  
There are two 82438FX components which provide data bus buffering and dual port buffering to the memory array.  
Controlled by the 82437FX, the 82438FX devices add one load each to the PCI bus and perform all the necessary byte  
and word swapping required. Memory and I/O write buffers are included in these devices. The TDP devices are 100 pin  
QFP packages.  
82371FB PCI ISA/IDE ACCELERATOR (PIIX)  
The 82371FB provides the interface between the PCI and ISA buses and integrates a dual channel fast IDE interface  
capable of supporting up to 4 devices, seven 32-bit DMA channels, five 16-bit timer/counters, two eight-channel interrupt  
controllers, PCI-to-AT interrupt mapping circuitry, NMI logic, ISA refresh address generation, and PCI/ISA bus  
arbitration circuitry. The PIIX comes in a 208-pin QFP package.  
TRITON DESIGN CONSIDERATIONS  
Triton Memory Hole Limitation  
Due the design of the Triton chipset, only one memory hole can be active at a time. The user can not set the Base  
Memory size to 512 KB and enable the ISA LFB at the same time.  
Triton PCI Hold Time Requirement  
The Triton chipset provides less hold time than the earlier Neptune and Mercury chipsets on the PCI address and data  
lines, but still is within the PCI specification. (The PCI specification calls out a 0 ns minimum hold time.) Some PCI  
expansion cards do not meet this requirement, and in fact require more hold time than the Triton chipset provides.  
Disabling PCI write bursting will sometimes enable these cards to function.  
Advanced/ZP Technical Product Summary · Page 7  
 
IDE SUPPORT  
The Advanced/ZP baseboard provides two independent high performance bus-mastering PCI IDE interfaces capable of  
supporting PIO Mode 3 and Mode 4 devices for up to 16 MB/sec transfers. Support for ATAPI devices is provided in the  
system BIOS. The system BIOS also supports Logical Block Addressing (LBA) and ECHS on both IDE interfaces. When  
used in conjunction with a special driver the IDE interface operates as a PCI bus master for optimum performance in a  
multi-tasking environment. One such driver is provided by Intel for the Windows 95 environment.  
NATIONAL SEMICONDUCTOR 87306 SUPER I/O CONTROLLER  
Control for the integrated serial ports, parallel port, floppy drive, RTC and keyboard controller is incorporated into a single  
component, the National Semiconductor 87306. This component provides:  
· Two NS16C550-compatible UARTs with send/receive 16 byte FIFO  
- Support for an IrDA compliant Infra Red interface  
· Multi-mode bi-directional parallel port  
- Standard mode; IBM and Centronics compatible  
- Enhanced Parallel Port (EPP) with BIOS/Driver support  
- High Speed mode; Enhanced Capabilities Port (ECP) compatible  
· Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)  
· Integrated Real Time Clock accurate within +/- 13 minutes/yr  
· Integrated 8042 compatible keyboard controller  
Configuration of these interfaces is possible via the CMOS Setup program that can be invoked during boot-up. The serial  
ports can be enabled as COM1, COM2 or disabled. COM2 can alternately be configured as an IRDA port. The parallel port  
can be configured as normal, extended , or disabled. The floppy interface can be configured for 720 KB, 1.2 MB, 1.44 MB,  
or 2.88 MB media. Header pins located near the back of the board allow cabling to use these interfaces.  
KEYBOARD INTERFACE  
The AT keyboard connector is located on the back panel side of the baseboard. The 5V lines to this connector is protected  
with a PolySwitch* circuit which acts much like a self-healing fuse, re-establishing the connection after an over-current  
condition is removed. While this device eliminates the possibility of having to replace a fuse, care should be taken to turn  
off the system power before installing or removing a keyboard.  
The integrated 8042 microcontroller contains the AMI Megakey keyboard controller code which, besides providing  
traditional keyboard control functions, supports Power-On/Reset (POR) password protection. The POR password can be  
defined by the user via the Setup program. The keyboard controller also provides for the following "hot key" sequences:  
· CTRL-ALT-DEL: System software reset. This sequence performs a software reset of the system by jumping to the  
beginning of the BIOS code and running the POST operation.  
· CTRL-ALT+ and CTRL-ALT-: Turbo mode selection. CTRL-ALT- sets the system for de-turbo mode, emulating a 25  
MHz AT, and CTRL-ALT+ sets the system for turbo mode. Changing the Turbo mode may be prohibited by an operating  
system, or when the CPU is in Protected mode or virtual 86 mode under DOS.  
· CTRL-ALT-<defined in setup>: Power down and coffee-break key sequences take advantage of the SMM features of  
the Pentium processor to greatly reduce the system’s power consumption while maintaining the responsiveness necessary  
to service external interrupts.  
REAL TIME CLOCK, CMOS RAM AND BATTERY  
The integrated Real Time Clock, RTC, is accurate to within 13 minutes/year. The RTC can be set via the BIOS SETUP  
Program. CMOS memory supports the standard 128-byte battery-backed RAM, fourteen bytes for clock and control  
registers, and 114 bytes of general purpose non-volatile CMOS RAM. All CMOS RAM is reserved for BIOS use. The  
CMOS RAM can be set to specific values or cleared to the system default values using the BIOS SETUP program. Also,  
Advanced/ZP Technical Product Summary · Page 8  
 
the CMOS RAM values can be cleared to the system defaults by using a configuration switch on the baseboard. Appendix  
B lists switch and jumper configurations.  
An external coin-cell style battery provides power to the RTC and CMOS memory. The battery has an estimated lifetime  
of seven years and is socketed for easy replacement. Refer to Appendix A for battery replacement details.  
IRDA (INFRARED) SUPPORT  
Serial port 2 can be configured to support an IrDA module via a 5 pin header connector. Once configured for IrDA, the  
user can transfer files to/from portable devices such as laptops, PDA’s and printers using application software such as  
LapLink. The IrDA specification provides for data transfers at up to 115kbps from a distance of 1 meter.  
A 5-pin header is provided to allow connection to a Hewlett Packard HSDSL-1000 compatible Infra-red  
transmitter/receiver.  
SYSTEM BIOS  
The Advanced/ZP baseboard uses an American Megatrends Incorporated (AMI) Pentium Processor ROM BIOS, which is  
stored in Flash EEPROM and easily upgraded using a floppy disk-based program. In addition to the AMIBIOS, the Flash  
EEPROM also contains the Setup utility, Power-On Self Tests (POST), update recovery code, and the PCI auto-  
configuration utility. This baseboard supports system BIOS shadowing, allowing the BIOS to execute from 32-bit on-  
board write-protected DRAM.  
The BIOS displays a sign-on message during POST identifying the type of BIOS and a five-digit revision code. As an  
example the BIOS for the Advanced/ZE will be 1.00.02.BS0. As BIOS updates occur the revision number will increase to  
1.00.03.BS0, and so on.  
Information on BIOS functions can be found in the IBM PS/2 and Personal Computer BIOS Technical Reference  
published by IBM, and the ISA and EISA Hi-Flex AMIBIOS Technical Reference published by AMI. Both manuals are  
available at most technical bookstores.  
FLASH IMPLEMENTATION  
The Intel 28F001BXT 1 Mb FLASH component is organized as 128K x 8 (128 KB). The Flash device is divided into five  
areas, as described in Table 1.  
System Address  
FLASH Memory Area

4 KB OEM LOGO Area  
48 KB System BIOS Reserved  
Table 2. Flash Memory Organization  
The FLASH device resides in system memory in two 64 KB segments starting at E0000H, and can be mapped two  
different ways, depending on the mode of operation. In Normal Mode, address line A16 is inverted, setting the E000H  
and F000H segments so that the BIOS is organized as shown in the system address column above. Recovery mode  
removes the inversion on address line A16, swapping the E000H and F000H segments so that the 8 KB boot block resides  
at FE000H where the CPU expects the bootstrap loader to exist. This mode is only necessary in the unlikely event that a  
BIOS upgrade procedure is interrupted, causing the BIOS area to be left in an unusable state. For information on  
recovering the BIOS in the event of a catastrophic failure, refer to the appendix.  
BIOS UPGRADES  
FLASH memory makes distributing BIOS upgrades easy. A new version of the BIOS can be installed from a diskette.  
BIOS upgrades will be available as downloadable files on the Intel bulletin board.  
The disk-based Flash upgrade utility, FMUP.EXE, has three options for BIOS upgrades:  
Advanced/ZP Technical Product Summary · Page 9  
 
· The Flash BIOS can be updated from a file on a disk;  
· The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the event that an  
upgrade cannot be successfully completed; or  
· The BIOS in the Flash device can be compared with a disk file to ensure the system has the correct BIOS version.  
The upgrade utility ensures the upgrade BIOS extension matches the target system to prevent accidentally installing a  
BIOS for a different type of system. A recovery jumper is provided to allow recovery in the unlikely event of an  
unsuccessful BIOS upgrade. The jumper forces the ROM decode to access a 8 KB block of write protected recovery code  
in the Flash device.  
SETUP UTILITY  
The ROM-based Setup utility allows the configuration to be modified without opening the system for most basic changes.  
The Setup utility is accessible only during the Power-On Self Test, POST, by pressing the <F1> key after the POST  
memory test has begun and before boot begins. A prompt may be enabled that informs the user to press the <F1> key to  
access Setup. A switch on the baseboard can be set to prevent user access to Setup for security purposes. Setup options are  
detailed in the BIOS appendix.  
PCI AUTO-CONFIGURATION  
The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow the insertion and  
removal of PCI cards to the system without user intervention. When the system is turned on after adding a PCI add-in  
card, the BIOS automatically configures interrupts, DMA channels, I/O space, and other parameters. The user does not  
have to configure jumpers or worry about potential resource conflicts. Because PCI cards use the same interrupt resources  
as ISA cards, the user must specify the interrupts used by ISA add-in cards in the Setup utility. The PCI Auto-  
Configuration function complies with version 2.10 of the PCI BIOS specification.  
ISA PLUG & PLAY  
The BIOS incorporates ISA Plug and Play capabilities conforming to version 1.0a of the Plug-n-Play specification. This  
will allow auto-configuration of Plug and Play ISA cards, and resource management for legacy ISA cards, when used in  
conjunction with the ISA Configuration Utility (ICU).  
SHADOW MEMORY  
Memory from C8000-DFFFF is not shadowed. This is a change from previous Intel products using AMI BIOS. This may  
have a slight adverse affect on the performance of some non-Plug and Play ISA cards. All or part of this area may be used  
as shared ISA memory if needed. Video BIOS located from C0000-C7FFF is shadowed to boost performance.  
POWER MANAGEMENT  
The Advanced/ZP will enable you to have an Energy Star compliant system through its Advanced Power Management  
resources. The Advanced/ZP BIOS supports power management via System Management Mode (SMM) interrupts to the  
CPU and Advanced Power Management (APM v1.1). In general, power management capabilities will allow the system to  
be put into a power managed Stand By state. This can be accomplished by pressing the sleep/resume button on the front  
of the chassis, entering an user configured hot-key sequence on the keyboard, or by the expiration of a hardware timer  
which detects system inactivity for a user-configurable length of time. While in the Stand By state, the Advanced/ZP  
baseboard reduces the system power consumption to Energy Star levels by utilizing the power saving capabilities of the  
â
Pentium Processor, spinning down the IDE hard drive, and turning off an Energy Star rated monitor. Add-in cards  
supplied with APM-aware drivers can also be put into a power managed state for further energy savings. The ability to  
respond to external interrupts is fully maintained while in Stand By mode allowing the system to service requests such as  
in-coming FAX’s or network messages while unattended.  
FLASH LOGO AREA  
Advanced/ZP supports a 4 KB programmable FLASH user area located at EC000-ECFFF. An OEM may use this area to  
display a custom logo. The BIOS accesses the user area at several points during the boot up sequence.  
Advanced/ZP Technical Product Summary · Page 10  
 
SECURITY FEATURES  
ADMINISTRATIVE PASSWORD  
The administrative password protects several sensitive Setup options from being viewable to a user unless the password  
is entered. These sensitive fields are viewable unless the administrative password is set.  
BIOS PASSWORD  
A BIOS password feature provides security during the boot process. A password can be entered using the Setup utility,  
and will be required on boot up before normal operation of the system can commence. To enable, disable, or change the  
password, refer to the Setup program options in the appendix.  
If the password is forgotten, it can be cleared by turning off the system and setting the "password clear" jumper to the  
clear position.  
SETUP ENABLE SWITCH  
A baseboard configuration switch controls access to the BIOS Setup utility. By setting switch SW5 to the ON position,  
the user is prevented from accessing the Setup utility during the Power-On Self Test or at any other time. The message  
prompting the user to press <F1> to enter setup is also disabled

Sleep/Resume  
This two pin header, when connected to a momentary switch, can be used to put the system into a power managed  
state (standby) that will reduce the system’s power consumption. If the system is in Stand By mode and the switch is  
pressed, the system will instantly wake up” or Resume full system activity. When used with a power supply with a  
high efficiency rating, the Advanced/ZE is easily capable of reducing the system power to below EPA Energy Star  
requirements. The function of the Sleep/Resume button can also be achieved via the keyboard with a hot key sequence  
programmable in setup.  
Infra-Red (IrDA) connector  
Serial port 2 can be configured to support an IrDA module via a 5 pin header connector. Once configured for IrDA,  
the user can transfer files to/from portable devices such as laptops, PDA’s and printers using application software such  
as LapLink. The IrDA specification provides for data transfers at up to 115kbps from a distance of 1 meter.  
Speaker  
The external speaker provides error beep code information during the Power-On Self Test if the system cannot use the  
video interface. See the appendix for more information about error beep codes.  
BACK PANEL CONNECTIONS  
The back panel provides external access to an AT style keyboard connector integrated on the Advanced/ZP baseboard.

Table A-1 shows the possible memory combinations. The Advanced/ZP will support both Fast Page DRAM or EDO  
DRAM SIMMs, but they cannot be mixed within the same memory bank. If Fast Page DRAM and EDO DRAM SIMMs  
are installed in separate banks, each bank will be optimized for maximum performance. Parity generation and detection is  
NOT supported. SIMM requirements are Fast Page Mode or EDO DRAM, 60 nS or 70 nS, with tin-lead connectors.

Appendix B - Jumpers and Switches  
Figure B-1. Jumper locations and settings (default settings shown)  
EXTERNAL CPU CLOCK SPEED (50/60/66 MHZ) - SWITCHES 7 & 8  
This jumper sets the CPU's external operating frequency at 50, 60, and 66 MHz.. Default setting is 50 MHz.

Table B-1. External CPU Speed Switches  
INTERNAL CPU BUS CLOCK SPEED - SWITCH 6  
Sets the internal processor speed to either 3/2 or 2 times the external CPU clock speed. Switch 6=OFF for 3/2, Switch  
6=ON for 2 times. The 3/2 setting is used for 75 MHz, 90 MHz, and 100 MHz processors. The 2 times setting is used for  
120 MHz processors. The default setting is 3/2, (Switch 6 = OFF).  
SETUP DISABLE - SWITCH 5  
Allows access to CMOS Setup Utility to be disabled by setting switch 5 to the ON position. Default is for access to setup to  
be enabled (switch 5 = OFF).  
CLEAR CMOS - SWITCH 4  
Allows CMOS settings to be reset to default values by moving switch 4 to the ON position and turning the system on. The  
system should then be turned off and switch 4 should be returned to the OFF position to restore normal operation. This  
procedure should be done whenever the system BIOS is updated. Default setting is SW4=OFF.  
PASSWORD CLEAR - SWITCH 3  
Allows system password to be cleared by moving switch 3 to the ON position and turning the system on. The system  
should then be turned off and switch 3 should be returned to the OFF position to restore normal operation. This procedure  
should only be done if the user password has been forgotten. Default setting is SW3=OFF.  
Advanced/ZP Technical Product Summary · Page 15  
 
PROCESSOR VOLTAGE REGULATION - SWITCH 2  
Sets the output of the on-board voltage regulator. The switch settings are OFF = VR, and ON = VRE. The VR voltage  
specification requires a voltage range of 3.3-3.465 Volts DC, while the VRE specification requires a voltage range of 3.45-  
3.6V. Pentium processors currently available that do not require the VRE voltage specification should use the VR setting.  
When upgrading your CPU be sure to consult the documentation for the processor voltage requirements before setting this  
switch, as an incorrect setting may damage the processor. The default position is with the switch set for VR (off).  
ISA BUS SPEED - SWITCH 1  
Sets the ISA bus speed to either 1/4 or 1/3 of the PCI bus speed to best maximize system performance for 75, 90, 100 or  
120 MHz processor speeds. When SW1=ON the ISA bus speed will be 1/4 of the PCI bus speed and when SW1=OFF the  
ISA bus speed will be 1/3 the PCI bus speed. The ISA bus speed is derived from the PCI bus speed which is derived from  
the external processor clock frequency. The position of SW1 will set the ISA bus speed to either Compatible or Enhanced  
for 90 MHz, 100 MHz, and 120 MHz processors and will leave the ISA bus speed Compatible for 75 MHz processor speed.  
For 90 MHz, 100 MHz, and 120 MHz processor speeds, if SW1 is set to Compatible (SW1=ON), the speed will fall within  
the limits defined by the IBM AT Technical Reference (6-8.33 MHz). If set to Enhanced (SW1=OFF), the speed will be  
greater than the maximum defined by the IBM AT Technical Reference manual. SW1 can be set to either position when a  
75 MHz processor speed is used for maximum ISA bus performance. Modern ISA cards can operate with the enhanced  
speeds, however some older cards can experience difficulties. The actual value of the Bus Clock when set to Compatible or  
Enhanced is dependent upon the setting of the external processor frequency. The following table describes the ISA bus  
speeds for the 75 MHz, 90 MHz, 100 MHz, and 120 MHz processor speeds.

RECOVERY BOOT ENABLE - J1K1  
This switch allows the system to boot in the event the system BIOS has been corrupted by moving the jumper from the  
default position of 1-2 to the 2-3 position. A recovery disk must be in drive A while booting up with this jumper set to 2-3.  
Once the recovery is complete the jumper should be move back to pins 1-2, and the system rebooted.

disabled. If the on board IDE controllers are not used, these IRQs may be used for ISA cards, even though they do not  
show up on the menu. These interrupts will not be used by PCI devices other than the IDE controllers, as they must  
remain available for bootable devices.  
SECURITY SCREEN  
This section describes the two access modes that can be set using the options found on the Security screen, and then  
describes the Security screen options themselves.  
ADMINISTRATIVE AND USER ACCESS MODES  
The options on the Security screen menu make it possible to restrict access to the Setup program by allowing you to set  
passwords for two different access modes: Administrative mode and User mode.  
In general, Administrative mode has full access to the Setup options, whereas User mode has restricted access to the  
options. Thus, by setting separate Administrative and User passwords, a system administrator can limit who can change  
critical Setup values. The actual limitations depend on whether either the Administrative or User passwords or both are  
set.  
If you want to limit access to who can boot the system, you must set the User password. This is the password that the  
system will ask for before booting. If only the Administrative password is set, the system will boot up without asking for  
a password. If both passwords are set, you can enter either password to boot the system.  
This table shows the effects of setting the Administrative and User passwords. (The table is for reference only, and is  
not shown on the Security screen.) In the table, the statement “Can change a limited number of options” means you can  
change the system date and time, the User password, and the security hot key.

When selected, this brings up a dialog box that allows you to set the User password.  
Advanced/ZP Technical Product Summary · Page 31  
 
Set Administrative Password  
When selected, this brings up a dialog box that allows you to set the Administrative password.  
Unattended Start  
When selected, this brings up a dialog box that allows you to control when the security password is requested. The  
options are Enabled and Disabled. The default is Disabled. The User password must be enabled before you can enable  
this option. If Enabled is selected, the system will boot, but the keyboard will be locked until the User password is  
entered.  
Security Hot Key (CTRL-ALT-)  
This allows you to set a hot key that, when pressed, will lock the keyboard until the User password is entered.  
EXIT SCREEN  
Exit Saving Changes  
When selected, this allows you to save the change to CMOS and exit the Setup program. You can also press the <F10>  
key anywhere in the Setup program to do this.  
Exit Discarding Changes  
When selected, this allows you to exit the Setup program without saving any changes. This means that any changes  
made while in the Setup program will be discarded and NOT SAVED. Pressing the <Esc> key in any of the four main  
screens will do this.  
Load Setup Defaults  
When selected, this allows you to reset all of the setup options to their defaults. You can also press the <F5> key  
anywhere in the Setup program to do this. This selection loads the default values from the ROM table.  
Discard Changes  
When selected, this allows you to discard any changes you made during the current Setup session without exiting the  
program. You can also press the <F6> key anywhere in the Setup program to do this. This selection loads the CMOS  
values that were present when the system was turned on.

Appendix H - BIOS Recovery  
The Advanced/ZE incorporates the AMIBIOS in a Flash memory component. Flash BIOS allows easy upgrades without the  
need to replace an EPROM. The upgrade utility fits on a floppy diskette and provides the capability to save, verify, and update  
the system BIOS. The upgrade utility also provides the capability to install alternate languages for BIOS messages and the  
SETUP utility. The upgrade utility can be run from a hard drive or a network drive, but no memory managers can be installed  
during upgrades.  
USING THE UPGRADE UTILITY  
If the utility is obtained from the bulletin board, UNZIP the archive and copy the files to a bootable MS-DOS 3.3, 4.01, 5.0,  
or 6.x diskette. Reboot the system with the upgrade diskette in the bootable floppy drive and follow the directions in the easy  
to use menu-driven program.  
RECOVERY MODE  
In the unlikely event that a FLASH upgrade is interrupted catastrophically, it is possible the BIOS may be left in an  
unusable state. Recovering from this condition requires the following steps (be sure a power supply and speaker have been  
attached to the board, and a floppy drive is connected as drive A:):  
1. Change Flash Recovery jumper to the recovery mode position.  
2. Install the bootable upgrade diskette into drive A:  
3. Reboot the system.  
4. Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the  
procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When  
the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As  
soon as the drive LED goes off, the recovery is complete.  
5. Turn the system off.  
6. Change the Flash Recovery jumper back to the default position.  
7. Leave the upgrade floppy in drive A: and turn the system on.  
8. Continue with the original upgrade.

Appendix I - Error messages and Beep Codes  
Errors can occur during POST (Power On Self Test) which is performed every time the system is powered on. Fatal errors,  
which prevent the system to continue the boot process, are communicated through a series of audible beeps. Other errors are  
displayed in the following format:  
ERROR Message Line 1  
ERROR Message Line 2  
For most displayed error messages, there is only one message. If a second message appears, it is "RUN SETUP". If this  
message occurs, press <F1> to run AMIBIOS Setup.
