96M4311o User’s Manual 1-1

Chapter 1
System Overview

1.1 Introduction

PCI Express x16 expansion interface and High reliability are two major reasons that
PICMG 1.3 Single Host Board (SHB) 96M4311o was developed.

The first two PCI Express chipsets that Intel® EID introduced to the world is 915GV &
915GM. Though 915GV supports powerful Intel® Pentium® 4/Celeron D processor
but it does not support PCI Express x16 interface which is latest expansion interface
of graphics card. Many applications are looking for high-end graphics card but in
vain with PCIMG standards such as PICMG 1.0/1.2 since the previous graphics card
interface, AGP external expansion does not support by those form factor. The
limitation finally resolved by presenting of PICMG 1.3. With this standard, SHB can
support external graphics card, therefore, user can choose the most wonderful
graphics card for their applications. As a result, 915GM was selected to be the kernel
of 96M4311o.

The SHB does not only provide PCI Express x16 expansion capability but also adopts
Pentium® M/Celeron M processor that only generates less than half TDP (Thermal
Design Power) of Pentium® 4/Celeron D processor. That benefits to power saving as
well as weight and noise of processor cooler. The reliability of the system
dramatically increased as a return.

3.5 WDT Function

The working algorithm of the WDT function can be simply described as a counting
process. The Time-Out Interval can be set through software programming. The
availability of the time-out interval settings by software or hardware varies from
boards to boards.

The 96M4311o allows users control WDT through dynamic software
programming. The WDT starts counting when it is activated. It sends out a signal to
system reset or to non-maskable interrupt (NMI), when time-out interval ends. To
prevent the time-out interval from running out, a re-trigger signal will need to be sent
before the counting reaches its end. This action will restart the counting process.

A well-written WDT program should keep the counting process running under
normal condition. WDT should never generate a system reset or NMI signal unless
the system runs into troubles.

The related Control Registers of WDT are all included in the following sample
program that is written in C language. User can fill a non-zero value into the
Time-out Value Register to enable/refresh WDT. System will be reset after the
Time-out Value to be counted down to zero. Or user can directly fill a zero value into
Time-out Value Register to disable WDT immediately.

To ensure a successful accessing to the content of desired Control Register, the
sequence of following program codes should be step-by-step run again when each
register is accessed.

Additionally, there are maximum 2 seconds of counting tolerance that should be
considered into user’ application program. For more information about WDT, please
refer to Winbond W83627THF data sheet.

There are two PnP I/O port addresses that can be used to configure WDT,

1) 0x2E:EFIR (Extended Function Index Register, for identifying CR index number)

2) 0x2F:EFDR (Extended Function Data Register, for accessing desired CR)

Below are some example codes, which demonstrate the use of WDT.

// Enter Extended Function Mode
outp(0x002E, 0x87);
outp(0x002E, 0x87);
// Assign Pin 89 to be a WDTO
outp(0x002E, 0x2B);
outp(0x002F, inp(0x002F) & 0xEF);

BIOS Setup Information

The 96M4311o is equipped with the Phoenix (AWARD) BIOS stored in Flash
ROM. These BIOS has a built-in Setup program that allows users to modify the basic
system configuration easily. This type of information is stored in CMOS RAM so that
it is retained during power-off periods. When system is turned on, 96M4311o
communicates with peripheral devices and checks its hardware resources against the
configuration information stored in the CMOS memory. If any error is detected, or
the CMOS parameters need to be initially defined, the diagnostic program will
prompt the user to enter the SETUP program. Some errors are significant enough to
abort the start-up.

4.1 Entering Setup

Turn on or reboot the computer. When the message “Hit <DEL> if you want to run
SETUP” appears, press <Del> key immediately to enter BIOS setup program.

If the message disappears before you respond, but you still wish to enter Setup,
please restart the system to try “COLD START” again by turning it OFF and then
ON, or touch the "RESET" button. You may also restart from “WARM START” by
pressing <Ctrl>, <Alt>, and <Delete> keys simultaneously. If you do not press the
keys at the right time and the system will not boot, an error message will be displayed
and you will again be asked to,

Press <F1> to Run SETUP or Resume

In HIFLEX BIOS setup, you can use the keyboard to choose among options or modify
the system parameters to match the options with your system. The table below will
show you all of keystroke functions in BIOS setup.

APIC Mode

Setting to Enabled can cause instabilities. Once the operating system is installed, such
as Windows XP in my case, this setting cannot be changed without reinstalling the
operating system, regardless of whether the initial setting is Disabled or Enabled. The
purpose of setting it to Enabled is to extend the number of IRQ's, which sounds like a
real risky proposition. I'm not surprised to see the conclusion reached at APIC:
Benefit or Trouble. The number of IRQ's should be fine without being extended,
anyway.

coordinates communications between the conventional PCI Express bus and PCI bus.
It must be stated that these items should never need to be altered. The default
settings have been chosen because they provide the best operating conditions for
your system. The only time you might consider making any changes would be if you
discovered that data was being lost while using your system.

Type the password, up to eight characters in length, and press <Enter>. The
password typed now will clear any previously entered password from CMOS
memory. You will be asked to confirm the password. Type the password again and
press <Enter>. You may also press <Esc> to abort the selection and not enter a
password.

To disable a password, just press <Enter> when you are prompted to enter the
password. A message will confirm the password will be disabled. Once the
password is disabled, the system will boot and you can enter Setup freely.

PASSWORD DISABLED

When a password has been enabled, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any part of
your system configuration.

Additionally, when a password is enabled, you can also require the BIOS to request a
password every time your system is rebooted. This would prevent unauthorized use
of your computer.

You determine when the password is required within the BIOS Features Setup Menu
and its Security option (see Section 3). If the Security option is set to “System”, the
password will be required both at boot and at entry to Setup. If set to “Setup”,
prompting only occurs when trying to enter Setup.

5.2 Onboard hardware installation

Q1: How do I connect my PS2 keyboard and mouse?

A: PS2 Keyboard and mouse cable is an option kit of 96M4311o. If you have PS2 kit

please connects it to J33 of 96M4311o.

Q2: OK. I have finished up hardware installation, but I got nothing when I power

on the system. Why?

A: There are thousands of different reasons to get this power on failure.

1. Check the 96M4311o jumper, JP9. For AT power supply or ATX power supply used
for AT system, JP9 needs to be opened. Incorrect power setting will not allow you
to power on the system.

2. Double check if every connector is attached with the correct cable.

3. Please move JP6 (CMOS clear Jumper) to 2-3, power on the system to clear CMOS
(move on/off switch from off to on for AT mode, or toggle the switch for ATX
mode), power off the system, move JP6 back to 1-2, and power on again.

Q3: I power on the system, but the CPU speed is not correct. Why?

A: This applies to Engineering Sample processor ONLY. If you have ever loaded

the BIOS optimal default, thank you for doing so. However, this will force the
BIOS to pick up the default CPU core/bus ratio as well. It needs to be emphasized
again that 96M4311o does not have switch or jumper to configure CPU core/bus
ratio. This is done through BIOS automatically. Please check in the
“Frequency/Voltage Control” section of Chapter 4 (4-11) to adjust this core/bus
ratio (only available when you plug in the engineering sample processor from
Intel). System default setting is automatically setting when you plug in
commercial processors from Intel and you will not see the CPU Clock Ratio item in
the BIOS setting screen.

Troubleshooting

96M4311o User’s Manual 5-6

Q4: I connect two IDE devices over one IDE flat cable, but the system either does

not start, or just hangs from time to time. Why ?

A: Make sure that you have configured the two IDE devices as a master and a slave,

respectively.

Q5: I am using an ATA-66 (or 100) hard drive, how can I know that ATA-66

function is started??

A: You need to use the 80-pin ATA-66 IDE flat cable to have this function ready.

During POST, you can see ATA-66 (or 100) message while hard drive is being
detected.

Q6: In addition to the above description, is there anything to do to finish up an

ATX system?

A: Yes. The 96M4311o needs to be configured to support ATX function for the above

cabling. Please move jumper JP4 to 3-5 short and 4-6 short (support ATX
function).

Q7: How can I build up an AT system using ATX power supply

A: The 96M4311o is able to emulation to AT system and power up automatically; Please

short a jumper cap on JP9 of 96M4311o to support AT function. Meanwhile, set
Bios setup menu “PWRON” after “PWR Fail” to auto power up function.

Q8: Can I connect SATA cable on PICMG 1.3 Backplane?

A: Yes, there are two SATA connectors on PBPE-13A8 and PBPE-06V Backplane. You

can choose connect the SATA cable from 96M4311o or PICMG 1.3 Backplane.

PBPE-13A8 PBPE-06V

Q9: Can I build a SATA Raid system ?

A: No. 96M4311o is used IHC6-M not ICH6-R (Raid) I/O controller,the ICH6-M

chipset doesn’t support raid system.

Q10: Can I connect USB ports on PICMG 1.3 Backplane?

A: Actually, 96M4311o resides 4 USB ports on PICMG 1.3 Backplane, you can use

USB peripheral through Backplane.

Q11: How do I configure 96M4311o to Stand along mode?

A: At standalone mode, the single board computer will connect no peripheral device

Cards, only 4-pin connector for CPU (J25) and the 4pin connector (J13) have
attached.

96M4311o User’s Manual 5-8

5.3 BIOS Setting

It is assumed that users have correctly adopted modules and connected all the device
cables required before turning on AT power. CPU, CPU fan, CPU fan power cable,
240-pin DDR2 SO-DIMM, keyboard, mouse, floppy drive, IDE hard disk, printer,
VGA connector, device power cables, ATX accessories or 12V 4-pin power cable are
good examples that deserve attention. With no assurance of properly and correctly
accommodating these modules and devices, it is very possible to encounter system
failures that result in malfunction of any device.

To make sure that you have a successful start with 96M4311o, it is recommended,
when going with the boot-up sequence, to hit “DEL” key and enter the BIOS setup
menu to tune up a stable BIOS configuration so that you can wake up your system far
well.

Loading the default optimal setting

When prompted with the main setup menu, please scroll down to “Load Optimal
Defaults”, press “Enter” and “Y” to load in default optimal BIOS setup. This will

force your BIOS setting back to the initial factory configuration. It is recommended to
do this so you can be sure the system is running with the BIOS setting that DSM
has highly endorsed. As a matter of fact, users can load the default BIOS setting any
time when system appears to be unstable in boot up sequence.

Auto Detect Hard Disks

In the BIOS => Standard CMOS setup menu, pick up any one from
Primary/Secondary Master/Slave IDE ports, and press “Enter”. Setup the selected
IDE port and its access mode to “Auto”. This will force system to automatically pick
up the IDE devices that are being connected each time system boots up.

Improper disable operation

There are too many occasions where users disable a certain device/feature in one
application through BIOS setting. These variables may not be set back to the original
values when needed. These devices/features will certainly fail to be detected.

When the above conditions happen, it is strongly recommended to check the BIOS
settings. Make sure certain items are set as they should be. These include the floppy
drive, COM1/COM2 ports, parallel port, USB ports, external cache, on-board VGA
and Ethernet.

Troubleshooting

96M4311o User’s Manual 5-9

It is also very common that users would like to disable a certain device/port to
release IRQ resource. A few good examples are

disable COM1 serial port to release IRQ #4
disable COM2 serial port to release IRQ #3
disable parallel port to release IRQ #7
disable PS/2 mouse to release IRQ #12,
…, etc.

A quick review of the basic IRQ mapping is given below for your reference.

IRQ# Description

IRQ #0 System Counter
IRQ #1 Keyboard
IRQ #2 Programmed Controller
IRQ #3 COM2
IRQ #4 COM1
IRQ #5 Display, Network , USB 1.0/1.1 UHCI Controller
IRQ #6 Floppy Disk Controller
IRQ #7 Printer Port (Parallel Port)
IRQ #8 CMOS Clock
IRQ #9 ACPI Controller

IRQ #10 USB 1.0/1.1 UHCI Controller , Multimedia Device ,

Network Controller
IRQ #11 SMBus , USB 1.0/1.1 UHCI, USB 2.0 EHCI Controller
IRQ #12 PS/2 mouse
IRQ #13 Data Processor
IRQ #14 Primary IDE Controller
IRQ #15 Secondary IDE Controller

It is then very easy to find out which IRQ resource is ready for additional peripherals.
If IRQ resource is not enough, please disable some devices listed above to release
further IRQ numbers.
