System Introduction 1-1

1.1 Overview

1.1.1 System Board

The M9B is a dual-processor system board that supports the Intel Pentium Pro CPU. It contains
an exclusive slot for the Pentium Pro CPU board that carries two zero-insertion force (ZIF) CPU
sockets.

This high-performance 64-bit system board utilizes both the EISA and the PCI local bus
architecture. Two EISA, four PCI bus slots, and one EISA/PCI shared slot reside on the board to
allow installation of either master or slave devices.

The system board has four DRAM banks composed of eight 72-pin SIMM sockets that
accommodate both fast-page mode and EDO (extended data output) SIMMs. The sockets support
a total of 256-MB system memory using 32-MB SIMMs.

A 50-pin Fast SCSI-II interface and a 68-pin Wide SCSI interface come with the system board to
connect SCSI devices. Standard external I/O interfaces include two 9-pin serial ports, one parallel
port, a video port, and keyboard and mouse ports.

The system board supports two optional features, the ASM Pro and the remote diagnostic
management (RDM), that allow better server management. The ASM Pro detects problems in
CPU thermal condition, 5V/3.3V/1.5V detection, and PCI bus utilization calculation. The RDM
allows execution of the RDM diagnostic program from a remote RDM station to fix detected
problems or to reboot the system.

1.1.2 CPU Board

The Pentium Pro CPU board carries two ZIF sockets (Socket 8) to accommodate the new Pentium
Pro CPUs running at 180 MHz and 200 MHz.

The board also includes the PCI bridge/memory controller (PMC) and the data bus
accelerator (DBX) chipsets. The PMC provides bus control signals and address paths for transfers
between the host bus, PCI bus, and the main memory. The DBX supoorts multiple-bit error
detection and sigle-bit error correction through the ECC/parity feature.

1.5 Hardware Configurations

1.5.1 Memory Configurations

The system board comes with eight 72-pin SIMM sockets that support 4-MB and 16-MB single­density SIMMs as well as 8-MB and 32-MB double-density SIMMs for a total system memory of
256-MB. The sockets support both the fast page mode and EDO 60/70 ns SIMMs.

Rules for Adding Memory

• You may use the memory banks (Bank0 ~Bank3) in any order.

• Use only one type of SIMM in a given bank. You may combine EDO or fast-page mode

SIMMs for a memory configuration as long as the SIMMs in each bank are of the same type.

• Use only SIMMs with the same capacity in a bank. For example, do not combine 8-MB and

16-MB SIMMs in a bank.

• Always install SIMMs in pairs. For example, for a total memory of 16 MB, install two 8-MB

SIMMs in a bank. You can not use a 16-MB SIMM alone for a 16-MB memory.

1.7.1 Memory Address Structure

M9B is a Pentium Pro system based on 440FX PCIset supports 4GB of addressable memory
space and 64 KB of addressable I/O space. The Pentium Pro processor family supports
addressing of memory ranges larger than 4GB via the REQa[4:0]# signals (see Chapter 4 for
details). The PMC claims any access over 4GB by terminating transaction (without forwarding it to
the PCI bus). Writes are terminated simply by dropping the data and the PMC returns all zeros for
reads.

DOS Area (0000-9FFFFh)

The DOX area is 640KB in size and it is further devided into two parts. The 512KB area at 0 to
7FFFFh is always mapped to the main memory controlled by the PMC, while the 128KB address
range from 080000 to 09FFFFh can be mapped to PCI or to main DRAM. By default this range is
mapped to main memory and can be diclared as a main memory hole by BIOS CMOS setup.

Video Buffer Area (A0000-BFFFFh)

The 128KB graphics adapter memory region in normally mapped to a video device on the PCI bus
(typically VGA controller). This region is also the default region for SMM space.

System Introduction 1-19

Expansion Area (C0000-DFFFFh), Extended System BIOS Area (E0000-EFFFFh)

This two areas can be assigned as shadow or disable(read/write for other use, not shadow for
expansion ROM BIOS use) states by BIOS CMOS setup. By manipulating the shadow attributes,
the PMC can “shadow” the expansion ROM BIOS into the main DRAM Typically, these blocks
are mapped through the PCI bridge to ISA space. Memory that is disabled is not remapped.

System BIOS Area (F0000-FFFFFh)

This area is a single 64KB segment. This segment can be assigned as shadow or disable
(read/write for other use, not shadow for system BIOS use) states by BIOS CMOS setup. By
manipulating the shadow attributes, the PMC can “shadow” system BIOS into the main DRAM.
Memory that is disabled is mot remapped.

Extended Memory Area

This memory area covers 100000h (1 MB) to FFFFFFFFh (4GB minus 1) address range and it is
devided into the following regions:

• DRAM memory from 1 MB to a Top of Memory

• PCI memory space from the Top of Memory to 4GB with two specific ranges

• APIC Configuration Space from FEC00000h (4GB minus 20 MB) to FEC0_FFFFh

• High BIOS area from 4GB to 4GB minus 2 MB

DRAM memory from 1 MB to a Top of Memory

The address range from 1 MB to the top of main memory is mapped to main DRAM address range
controlled by PMC. All accesses to addresses within this range are forwarded by the PMC to the
DRAM unless a hole in this range is created by BIOS CMOS setup.

PCI memory space from the Top of Memory to 4GB with two specific ranges

The address range from the top of main DRAM to 4GB is normally mapped to PCI. The PMC
forwards all accesses within this address range to PCI.

There are two sub-ranges within this address range defined as APIC configuration space and high
BIOS address range.

APIC Configuration Space from FEC00000h (4GB minus 20 MB) to FEC0_FFFFh

This range is reserved for APIC(Advanced Programmable Interrupt Controller) configuration space
which includes the default I/O APIC configuration space.

The Pentium Pro accesses to the Local APIC configuration space do not result in external bus
activity since the Local APIC configuration space is internal to the Pentium Pro CPU.

1-20 Service Guide

High BIOS area from 4GB to 4GB minus 2 MB

The top 2 MB of the Extended Memory Region is reserved for System BIOS (High BIOS),
extended BIOS for PCI devices, and the A20 alias of the system BIOS. The CPU begins
execution from the High BIOS after reset. This region is mapped to the PCI so that the upper
subset of this region is aliased to 16 MB minus 256KB range.

Memory shadowing

A block of memory that can be desiged as “shadowed” into PMC DRAM memory. Typically this is
done to allow ROM code to execute more rapidly our of main DRAM. ROM is used as a read-only
during the copy process while DRAM at the same time is designated write-only. After copying, the
DRAM is designated read-only so that ROM is shadowed. CPU bus transactions are routed
accordingly. The PMC does not respond to transactions originating from the PCI or ISA masters
and targeted at shadowed memory blocks.

The master device request from ISA and EISA Bus are centralized arbitrated by PCEB, then
convey to 82439HX. The ESC generates the EISA Master Acknowledge (MACK[2:0]) signals in
response to the Master Request (MREQ[2:0]) signals from EISA master devices. The ESC has a
DMA controller includes the DISA Bus arbiter which works with the 82439HX’s PCI bus arbiter.
This arbiter determines which requester from among the requesting ISA Bus DMA master, EISA
Bus master, the PCI Bus, or Refresh should have the bus.

System Introduction 1-21

The 82439HX’s PCI bus arbiter allows PCI peer-to peer traffic concurrent with CPU main
memory/second level cache cycles. The arbiter supports five PCI masters. REQ[3:0]#/GNT[3:0]#
are used by PCI master devices. PHLD#/PHLDA# are the arbitration request/grant signals for the
PCEB and provide guaranteed access time capability for ISA masters. PHLD#/PHLDA# also
optimize system performance base on PCEB know policies. The arbitration mechanism is
enhanced with a multi-transaction timer mechanism. This feature improves the PCI bandwidth
allocation to short bursts, and important consideration for example, with typical video capture
devices.

The 82439HX integrates a high performance write-back second level cache controller using
internal/external tags and provides a full first-level and second-level cache coherency mechanism.
The second level cache is direct mapped, non-sectored, and supports a write-back cache policy.
Cache lines are allocated on read misses (not write allocate).

The second-level cache is configured to support 512-KB cache using synchronous pipeline burst
SRAMs. A second level cache line is 32-byte wide, and the second level cache contains 16K
lines. Valid and modified status bits are kept on a per-line basis. Cacheability of the entire
memory space in first-level cache is supported. The memory space cacheability for the secondary
cache is 512 MB of the system memory. See Figure 1-12.

APICINTR

Figure 1-14 Dual-processor Operating Logic

The MP specification defines three different interrupt modes as follows:

1. PIC Mode - effectively bypasses all APIC component and forces the system to operate in
single-processor mode.

2. Virtual Wire Mode - uses an APIC as a virtual wire, but otherwise operates the same as PIC
Mode.

3. Symmetric I/O Mode - enables the system to operate with more than one processor.

In M9A system, the virtual wire mode is adapted when only one processor installed. In virtual wire
mode, the 8259A-equivalent PIC fields all interrupts, and the local APIC becomes a virtual wire,
which delivers interrupts from the PIC to the processor via the local APIC’s local interrupt 0
(LINTIN0). The LINTIN0 pin of the local APIC is programmed as ExtINT, specifying to the APIC
that the PIC is to serve as an external interrupt controller. Whenever the local APIC finds that a
particular interrupt is of type ExtINT, it asserts the ExtINTA transaction along with the PINT
interrupt to the processor. In this case, the I/O APIC is not used.

In symmetric I/O Mode, the I/O interrupt are generated by the I/O APIC. All 8259 interrupt lines
are either masked or work together with the I/O APIC in a mixed mode. This hardware supports a
mode of operation in which the system can switch easily to symmetric I/O Mode from virtual wire
mode.

1.8 Power Management

1.8.1 Power Management Modes

The system has three power management modes: normal mode, IDE hard disk standby mode,
and system suspend mode.

Normal Mode

The normal operating mode of the system.

IDE Hard Disk Standby Mode

The IDE hard disk standby mode that controls ATA power-management-compliant hard disk
drives. This feature allows the device to enter into IDE hard disk standby mode after a specified
HDD non-activity period, and to return to normal mode immediately after a hard disk access.

The IDE hard disk standby mode has the following features:

• HDD power-management timer (1-15 minutes, time step = 1 minute)

• Allows HDD to go into standby mode (for ATA standard interface)

• Resume method: Any IDE HDD activity

System Suspend Mode

This is a fast-on, power-saving mode, allowing the PC to return to full power immediately. It
allows the VGA monitor to enter standby mode and turns off the hard disk drive spindle motor.
Any system activity returns the system to full power.

The system standby mode has the following features:

• Global power-management timer (1-15 minutes, time step = 1 minute)

• HDD goes into standby mode (for ATA standard interface)

• Disables H-sync and V-sync signals to control the VESA DPMS monitor

• LED on the panel flashes at 1.6-second intervals

• Resume method: Activity from keyboard, mouse, or any IRQ/DRQ enabled in the CMOS

BIOS Setup Information

BIOS Setup Information 3-1

Most systems are already configured by the manufacturer or the dealer. There is no need to run
Setup when starting the computer unless you get a configuration error. The Setup program loads
configuration values into the battery-backed nonvolatile memory called CMOS RAM. This
memory area is not part of the system RAM. If you repeatedly receive Run Setup messages, the
battery may be bad. In this case, the system cannot retain configuration values in CMOS.

3.1 Entering Setup

To enter Setup, press the key combination + +

3.2.6 IDE Features

Hard Disk Block Mode

This function enhances disk performance depending on the hard disk in use. If you set this
parameter to Enabled, it allows data transfer in block (multiple sectors) by increasing the data
transfer rate to 256 bytes per cycle. If your system does not boot after enabling this parameter,
change the setting to Disabled . This parameter is normally set to Disabled .

Hard Disk Size > 504 MB

This enhanced IDE feature works only under DOS and Windows 3.x environment. If enabled, it
allows you to use a hard disk with a capacity of more than 504 MB. This is made possible through
the Logical Block Address (LBA) mode translation. Other operating systems require this
parameter to be set to Disabled .

To prevent data loss, keep this parameter to Enabled if you are using a hard disk with more than
504 MB capacity and was previously configured through LBA mode. When you use a hard disk
configured through the cylinder-head-sector (CHS) mode, set this parameter to Disabled .

3.2.7 Large Memory Support Mode

This parameter allows the system to support an extended memory higher than 64 MB. Set this
parameter to Advanced if you are working under Windows NT environment and the system
memory size is greater than or equal to 64 MB. Otherwise, set it to Normal.

3.2.8 Num Lock After Boot

This parameter allows you to activate the Num Lock function upon booting. The default setting is

Enabled .

3.2.9 Memory Test

When set to Enabled, this parameter allows the system to perform a RAM test during the POST
routine. When set to Disabled, the system detects only the memory size and bypasses the test
routine. The default setting is Disabled .

This item is fixed to Disabled and is not user-configurable if you enabled the Auto Configuration
Mode and the Fast Boot Mode parameters on page 2 of the Basic System Configuration menu.
See section 3.2.10 and 3.2.11.

3.2.10 Auto-configuration Mode

When enabled, this parameter automatically sets the system configuration values to their
optimized settings. At the same time, it causes the Memory Test parameter to be fixed to

Disabled and the shadow RAM region for system and video BIOS to Enabled. See sections

3.2.9 and 3.3.1.
Set this parameter to Enabled if you do not know the hard disk drive type parameters and the

onboard communication port configuration.

BIOS Setup Information 3-7

3.2.11 Fast Boot Mode

When enabled, this parameter allows the system to boot faster by skipping some POST routines.
It bypasses memory test, enables Shadow RAM, and enables primary- and second-level cache.

When set to Enabled, this parameter also causes the Memory Test parameter to be fixed to

Disabled and the shadow RAM regions for system and video BIOS to Enabled . See sections

3.2.9 and 3.3.1.

3.3 Advanced System Configuration

The Advanced System Configuration option allows you to configure the advanced system memory
functions.

3.3.1 Shadow RAM

The system reserves 384 KB of random access memory (RAM) for the shadow RAM function.
This parameter has eight range addresses. When you set these addresses to Enabled, the
system BIOS, video BIOS, and I/O ROM functions run directly from the shadow RAM for faster
operation. When you set them to Disabled, the functions run normally from ROM.

The address range E0000h - FFFFFh is for shadowing the system BIOS. This item is always set
to Enabled and is not user-configurable. The address range C0000h - C7FFFh is for shadowing
the video BIOS. This item is fixed to Enabled and is not user-configurable if the Auto
Configuration Mode and the Fast Boot Mode parameters on page 2 of the Basic System
Configuration menu are enabled. Otherwise, you can disable this item.

The remaining address ranges are for I/O ROM functions.

3.3.2 L1 & L2 Cache (CPU Cache)

This parameter enables or disables the first- and second-level cache memory in the Pentium Pro
CPU.

Cache Scheme

This parameter sets the cache to Write-through or Write-back modes. Write-back updates
the cache but not the memory when there is a write instruction. It updates the memory only when
there is an inconsistency between the cache and the memory. Write-through updates both the
cache and the memory whenever there is a write instruction.

3.3.3 ECC/Parity Mode Selection

This parameter allows you to enable or disable the ECC and parity check feature. Fast-page
mode SIMMs with parity supports both ECC and parity mode. EDO SIMMs with parity supports
only ECC mode. You must disable this parameter if you installed SIMMs without parity.

Operation of ECC

This parameter allows you to select the error detection mode. The following are the ECC
operation options.

• None - detects single-bit errors and automatically corrects any error but does not set the

single-bit error flag in the chipset. In this option, the operating system does not receive any
signal even if there are system errors.

• Single-bit - detects single-bit errors, automatically corrects any error, and sets the single-bit

error flag in the chipset. The setting of the single-bit error flag is a signal to the operating
system that ECC detected single-bit errors.

• Multiple-bit - detects multiple-bit errors and sets the multiple-bit error flag in the chipset

but does not correct the errors. The setting of the multiple-bit error flag is a signal to the
operating system that ECC detected multiple-bit errors.

BIOS Setup Information 3-9

• Both - detects both single- and multiple-bit errors but corrects only single-bit errors. This

option sets both the single-and multiple-bit flags in the chipset to send signals to the operating
system that ECC detected errors.

3.3.4 Memory at 15MB-16MB

To prevent memory address conflicts between the system and expansion boards, reserve this
memory range for the use of either the system or an expansion board. Before setting this
parameter, check your add-on card manual to determine if your add-on card needs this memory
space. If not, set this parameter to System Use .

3.4.1 PCI IRQ Setting

This parameter allows for Auto or Manual configuration of PCI devices. If you use plug-and­play (PnP) devices, you can keep the default setting Auto. The system then automatically
configures the PnP devices. If your PCI device is not a PnP, you can manually assign the
interrupt for each device. Refer to your manual for technical information about the PCI card.

When the PCI IRQ Setting is set to Auto, all the IRQ setting fields
become gray and non-configurable.

PCI Slots

These parameters allow you to specify the appropriate interrupt for each of the PCI devices. For
PCI slots 1 and 2 which operate on PCI bus 0, you can assign IRQ3, IRQ4, IRQ5, IRQ7, IRQ9,
IRQ10, IRQ11, IRQ12, IRQ14, and IRQ15.

3-10 Service Guide

For PCI slots 3, 4, and 5 which operate on PCI bus 1, you can assign IRQ4, IRQ9, IRQ10, IRQ11,

3-12 Service Guide

Refer to your non-PnP ISA card manual when setting the following
parameters.

3.5.1 IRQ/DMA

These items allow you to assign specific IRQ and DMA channels to non-PnP ISA cards. The
system will not use such IRQ and DMA channels when it automatically assigns channels to PnP
cards.

3.5.2 Expansion ROM Region

These items specify the memory regions available for add-on card use. It allows you to manually
assign specific regions to non-PnP cards so that the system will not use those regions anymore
when it automatically configures PnP cards.

3.5.3 I/O Region

The items under this parameter allow you to reserve 16-byte memory address ranges for non-PnP
cards. When the system configures PnP cards, the address ranges that you marked will not be
used anymore.

You can assign memory addresses to non-PnP cards at random as long as you cover the address
range required by the card. For example, for a card that requires 178h-188h address, you have to
set regions 170h-17Fh and 180h-18Fh to Yes.

Mode 3 1. Server paging
Mode 4 1. Server paging

2. Server auto-reboot
Mode 5 1. Server paging

2. Server reboot

3. Server dial out to station
Disabled Disables RDM function

The default setting is 1.

Mode 1

Mode 1 requires manual station notification. This indicates that once RDM is activated and the
RDM LED turns on1 the server administrator must call the RDM station to notify the service
engineer about the server status. Once the service engineer at the RDM station site is informed
and confirmed the server status, he must run the RDM-station software in order to establish
communication with the RDM agent.

After executing the RDM-station software, the RDM-station application window appears on screen.
Under the Settings option, the service engineer must enter the correct server phone number,
station phone number, and RDM password. The entered password must be the same as the one
specified in the RDM remote connection password BIOS parameter. Otherwise, remote
connection cannot be established. Refer to the RDM User’s Guide for more details on the
RDM-station application.

If remote connection is successfully established, the server automatically reboots. After reboot, it
automatically enters the BIOS utility and allows the RDM station to check and reconfigure the
server BIOS settings, if necessary. After making your modification, reboot the server.

1

A lighted RDM LED indicates either of the following:
a. RDM button is pressed

b. RDM driver has detected server failure.

For more details on activating RDM, see section 3.3.

3-20 Service Guide

Mode 2

Once RDM is activated, the RDM module contacts the pager number specified in the RDM system
critical paging number parameter. Once the server engineer received the notification, he must run
the station software to establish communication with the RDM agent.

When connection is established, the station undergoes the same process as in Mode 1 wherein
RDM module requires a password and the remote station phone number to establish the RDM
connection.

Mode 3

Mode 3 is also called as the debug mode. When the server fails or hangs, the RDM module
contacts the pager number specified in the RDM system critical paging number parameter. After
the pager notification, the RDM module automatically isolates the RDM agent and deactivates the
RDM program to prevent the station from accessing the server. This means that you cannot
reboot the server unless you are at the RDM agent site and have direct access to the system.

This mode requires direct server access.

In this mode, notice that the RDM LED is OFF. This indicates that
the RDM function is deactivated.

We recommend you NOT to select this setting unless you want to
disregard the RDM function.

Mode 4

In this mode, when RDM is activated due to server failure, the RDM module contacts the pager
number specified in the RDM system critical paging number parameter and automatically reboots
the server without asking for a password or the remote station phone number. After rebooting, the
server enters normal mode.

This option allows you to minimize the system downtime.

Mode 5

Once the server fails or hangs, the RDM module contacts the specified pager number, reboots the
server, then connects to the RDM station. The RDM station modem must be ON and the system
must be running the RDM-station application in order to establish communication. Otherwise, the
signal sent by the module will not be received by the station at once.

After reboot, the BIOS utility appears on station screen and automatically disconnects the RDM­agent keyboard to enable the RDM station function as the main console. This also allows the
station to check and reconfigure the server BIOS settings. After modifying the BIOS settings,
reboot the server.

BIOS Setup Information 3-21

In this mode, if the RDM agent fails to establish connection with the
station, it automatically reboots and enters normal mode (same as
in Mode 4).

Disabled

This setting disables the RDM function and puts the system into normal mode. In normal mode,
the system I/O chip allows COM2 port to function as the modem controller. Since the RDM
module deactivates the RDM function, the server is protected from unauthorized and unnecessary
access.

3.7.2 RDM System Critical Paging Number

This parameter allows you to set the pager number that the RDM module must contact once the
server fails or hangs. To enter the pager number, simply highlight the parameter. Type in the
pager number followed by six commas (,). The commas specify the delay. Make sure that you
enter six commas; otherwise, the pager may not receive the complete message.

You may also include the RDM agent modem number or the message that you want to send in the
pager notification. To do this, simply enter the numbers after the comma signs. The valid entries
are 0 to 9 and asterisk (*). Also, these numbers must start and end with the number (#) sign.

To bypass this feature, do not enter any number after the comma signs.

RDM is activated under the RDM work mode 5 setting. To set, simply highlight the parameter and
enter the station phone number.

RDM remote connection phone number [5455299]

If the remote connection phone number is utilizing PBX line, then you must enter six commas (,)
after the entry phone number followed by the extension number, if any. When entering the
extension number, we recommend that you insert a comma after each number. The commas
specify delay.

RDM remote connection phone number [5455299,,,,,,6,6,4,9]

Leave the parameter blank to disregard the feature.

3.7.4 RDM Remote Connection Password

This parameter prevents unauthorized access of the RDM agent. To set a password, simply
highlight the parameter and enter your code. Your password may contain up to eight characters.
If you specify a password, make sure to take note of it. You will need enter the correct password
before the RDM station gains access to the RDM agent. If you want to bypass the password
feature, leave the parameter blank. When prompted for the password during RDM operation,
