The Intel Advanced/ZP baseboard features the Pentium 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 OverDrive 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.

CPU

PIN 1

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 iCOMP index 610 \ 75 MHz, 735 \ 90 Mhz, 815 \ 100 Mhz, and 1000 \ 120 Mhz. The Pentium
processor is backward-compatible with the 8086, 80286, i386 and i486 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.

Processor Speed Supported by PBA Numbers:

75 MHz All PBAs

90 MHz All PBAs

PERFORMANCE UPGRADE

A 320-pin Type 5 Zero Insertion Force socket provides users with a performance upgrade path to future, higher speed,
Pentium 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.

transfers

• Enhanced Fast DMA controller

• Interrupt controller and steering

• Counters/Timers

• SMI interrupt logic and timer with Fast On/Off mode

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

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 auto­configuration utility. This baseboard supports system BIOS shadowing, allowing the BIOS to execute from 32-bit on­board 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.

EE000H EFFFFH 8 KB Boot Block (Not FLASH erasable)
ED000H EDFFFH 4 KB Plug and Play ESCD Storage Area
EC000H ECFFFH 4 KB OEM LOGO Area
E0000H EBFFFH 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 Auto­Configuration 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
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.

SYSTEM MEMORY

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.

Frequency Switch 7 Switch 8

50 MHz OFF OFF

60 Mhz ON OFF

66 MHz OFF ON

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.

Internal Processor Frequency PCI bus Frequency SW1=OFF (1/3) SW1=ON (1/4)

75 MHz 25 MHz 8.33 MHz 8.33 MHz

90 MHz 30 MHz 10.0 MHz 7.50 MHz
100 MHz 33 MHz 11.0 MHz 8.33 MHz
120 MHz 30 MHz 10.0 MHz 7.50 MHz

Table B-2. ISA Bus Speed Switch Settings

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.

Number of Cylinders

If Hard Disk Type is set to User Definable, you must type the correct number of cylinders for your hard disk. If Hard
Disk Type is set to Auto Configured, this reports the number of cylinders for your hard disk and cannot be modified.

Number of Heads

If Hard Disk Type is set to User Definable, you must type the correct number of heads for your hard disk. If Hard Disk
Type is set to Auto Configured, this reports the number of heads for your hard disk and cannot be modified.

Number of Sectors

If Hard Disk Type is set to User Definable, you must type the correct number of sectors for your hard disk. If Hard Disk
Type is set to Auto Configured, this reports the number of sectors for your hard disk and cannot be modified.

Maximum Capacity

This reports the maximum capacity of your hard disk. It is calculated from the number of cylinders, heads, and sectors.
This is informational only, and there are no options here.

Initialization Timeout

When selected, this brings up a dialog box that allows you to specify the amount of time the system allows for auto­configuring an IDE drive before reporting that a drive is not present. The options are Disabled, 5, 10, or 31 seconds.
The default setting for drive C: is 5 seconds, and the default for drives D:, E:, and F: is Disabled. To decrease boot-up
time, you can set the time-out specification to Disabled for any drive not in the system. Furthermore, many hard drives
do not require 5 seconds for auto-configuration. You may try setting the time-out to Disabled for a hard drive in your
system. When set to Disabled, the system will try to auto-configure your drive once. If you set the time-out to Disabled
and the drive is not detected, reset the time-out to a higher setting.

IDE Translation Mode

When selected, this brings up a dialog box that allows you to specify the IDE translation mode. The options are
Standard CHS (standard cylinder head sector — less than 1024 cylinders), Logical Block Addressing (LBA), Extended
CHS (extended cylinder head sector — greater than 1024 cylinders), and Auto Detected (BIOS detects IDE drive
support for LBA). The default is Auto-detected.

Do not change this from the option selected when the hard drive was formatted. Changing the option may result in
corrupted data or drive not properly recognized.

Multiple Sector Setting

When selected, this brings up a dialog box that allows you to set the IDE programmed I/O cycles so that multiple
sectors are transferred in a single block. This only affects drives connected to the ISA/IDE connector. The options are
Disabled, 4 Sectors/Block, 8 Sectors/Block, or Auto Detected. The default is Auto Detected. Check the specifications
for your hard disk drive to determine which setting will provide the optimum performance for your drive.

Fast Programmed I/O Modes

When selected, this brings up a dialog box that allows you to set how fast transfers on the PCI IDE interface occur. The
options are Disabled or Auto Detected. The default is Auto Detected. If set to Disabled, transfers occur at an un­optimized speed. If set to Auto Detected, transfers occur at the drive’s maximum speed.

IRQ 3, 4, 5, 7, 9, 10, 11, 12

When selected, this brings up a dialog box that allows you to set the status of the IRQ. The options are Available and
Used By ISA Card. The default is Available. The PCI auto-configuration code looks here to see if these interrupts are

Advanced/ZP Technical Product Summary • Page 30

available. If an interrupt is available, the PCI auto-configuration code can assign the interrupt to be used by the system.
If your system contains an ISA agent that uses one of these interrupts, select Used By ISA Card for that interrupt.

Some of these interrupts may not be displayed if they already have been assigned to other peripherals, such as IRQ 3
and IRQ 4, which are normally used by the serial ports, and IRQ 7 for the parallel port, and IRQ12 for the mouse port.

Note: One IRQ is required for PCI devices. When selecting IRQs for use by ISA the BIOS will not allow you to select
all IRQs as used by ISA.

Note: IRQ 14 and IRQ 15 will not show up on the list of available IRQs, even when the on board IDE controllers are
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.

Password Set Administrative mode can: User mode can: Pswd Required at Boot

Neither Change all options* Change all options* None
Administrative only Change all options Change a limited number of options None
User only N/A Change all options User
Both Change all options Change a limited number of options Administrative or User

* If no password is set, any user can change all Setup options.

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.

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.

Advanced/ZP Technical Product Summary • Page 32

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.
