Installing the CPU

The IB780 CPU Card supports a Socket 370 processor socket for Intel
Pentium III and Celeron processors.

The Socket 370 processor socket comes with a lever to secure the
processor. Raise this lever to about a 90° angle to allow the insertion of
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, return the
lever to the lock position. Refer to the figures below.

After you have installed the processor into the socket, check if the
jumpers for the CPU type and speed are correct.

NOTE:

Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.

INSTALLATION

IB780 User’s Manual 7

MicroPCI Daughter Card Installation

The IB780 CPU card is integrated with a MicroPCI socket that use
SO-DIMM 144-pin connectors. These sockets can accommodate the
optional MicroPCI daughter cards.

To insert the MicroPCI daughter cards, position it at 30° to the PCB and
gently push it into the MicroPCI connector (See Figure 1 below). The
card will not fit when inserted at an angle of 45° or 15 °. Once inserted,
slowly press the card towards the PCB until it locks on both sides to the
clips of the connector. Screw the card to the PCB to secure the
installation. To remove the MicroPCI card, pull the ‘clips’ sideways as
shown in Figure 2 below.

BIOS Introduction

The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel Pentium II/III processors. The
BIOS provides critical low-level support for a standard device such as
disk drives, serial ports and parallel ports. It also adds virus and
password protection as well as special support for detailed fine-tuning of
the chipset controlling the entire system.

BIOS Setup

The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the <Del> key immediately allows you
to enter the Setup utility. If you are a little bit late pressing the <Del>
key, POST (Power On Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by
turning the system Off and back On again. The following message will
appear on the screen:

Press <DEL> to Enter Setup

In general, you press the arrow keys to highlight items, <Enter> to select,
the <PgUp> and <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.

When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

on the currently highlighted item in the list.

Note:

If the system cannot boot after making and saving system
changes with Setup, the Award BIOS supports an override to
the CMOS settings that resets your system to its default.

Warning:

It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been

Virus Warning

This item protects the boot sector and partition table of your hard disk
against accidental modifications. If an attempt is made, the BIOS will
halt the system and display a warning message. If this occurs, you can
either allow the operation to continue or run an anti-virus program to
locate and remove the problem.

CPU Internal Cache / External Cache

Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on up
contain internal cache memory, and most, but not all, modern PCs have
additional (external) cache memory. When the CPU requests data, the
system transfers the requested data from the main DRAM into cache
memory, for even faster access by the CPU. These items allow you to
enable (speed up memory access) or disable the cache function. By
default, these items are Enabled.

BIOS SETUP

32 IB780 User’s Manual

CPU L2 Cache ECC Checking

This field enables or disables the ECC (Error Correction Checking)
checking of the CPU level-2 cache. The default setting is Enabled.

Processor Number Feature

When enabled, this feature allows external systems to detect the
processor number/type of the CPU.

Quick Power On Self Test

When enabled, this field speeds up the Power On Self Test (POST) after
the system is turned on. If it is set to Enabled, BIOS will skip some
items.

These fields determine the drive that the system searches first for an
operating system. The options available include Floppy, LS/ZIP, HDD­0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, LAN and Disable.

Boot Other Device

These fields allow the system to search for an operating system from
other devices other than the ones selected in the First/Second/Third Boot
Device.

Swap Floppy Drive

This item allows you to determine whether or not to enable Swap Floppy
Drive. When enabled, the BIOS swaps floppy drive assignments so that
Drive A becomes Drive B, and Drive B becomes Drive A. By default,

this field is set to Disabled.

Boot Up Floppy Seek

When enabled, the BIOS will seek whether or not the floppy drive
installed has 40 or 80 tracks. 360K type has 40 tracks while 760K, 1.2M
and 1.44M all have 80 tracks.

Boot Up NumLock Status

This allows you to activate the NumLock function after you power up
the system.

generate only one instance. When enabled, you can set the two typematic
controls listed next. By default, this field is set to Disabled.

Typematic Rate (Chars/Sec)

When the typematic rate is enabled, the system registers repeated
keystrokes speeds. Settings are from 6 to 30 characters per second.

Typematic Delay (Msec)

When the typematic rate is enabled, this item allows you to set the time
interval for displaying the first and second characters. By default, this
item is set to 250msec.

Security Option

This field allows you to limit access to the System and Setup. The default
value is Setup. When you select System, the system prompts for the User

DRAM Clock

This setting sets the DRAM clock frequency. The default sets it based on
the Host CPU clock (front side bus).

DRAM Timing by SPD

This field sets the DRAM Timing based on SPD. The default setting is
Disabled.

SDRAM Cycle Length

This feature is similar to SDRAM CAS Latency Time. It controls the
time delay (in clock cycles - CLKs) that passes before the SDRAM starts
to carry out a read command after receiving it. This also determines the
number of CLKs for the completion of the first part of a burst transfer.
Thus, the lower the cycle length, the faster the transaction. However,
some SDRAM cannot handle the lower cycle length and may become
unstable. So, set the SDRAM Cycle Length to 2 for optimal performance
if possible but increase it to 3 if your system becomes unstable.

Bank Interleave

This decides how multiple memory modules communicate. Enable or
Disable this. It will only make a difference if you have more than one
memory module.

BIOS SETUP

IB780 User’s Manual 35

Memory Hole

It is recommended to leave as disabled, although enabling 15M-16M can
help with sound issues.

P2C / C2P Concurrency

Set to Disabled for best performance. You may set this to Enabled if you
want any sort of system stability.

Fast R-W Turn Around

Leave it as Enabled for ‘faster’ performance.

System BIOS Cacheable

The setting of Enabled allows caching of the system BIOS ROM at
F000h-FFFFFh, resulting in better system performance. However, if
any program writes to this memory area, a system error may result.

Video BIOS Cacheable

The Setting Enabled allows caching of the video BIOS ROM at
C0000h-F7FFFh, resulting in better video performance. However, if
any program writes to this memory area, a system error may result.

Frame Buffer Size

The default setting of the frame buffer size is 8M.

CPU Latency Timer

The default setting for the CPU Latency Timer is Enabled.

AGP Aperture Size

The field sets aperture size of the graphics. The aperture is a portion of
the PCI memory address range dedicated for graphics memory address
space. Host cycles that hit the aperture range are forwarded to the AGP
without any translation. The default setting is 64M.

OnChip USB

The default setting of this filed is Enabled to enable the USB function on
board.

OnChip Keyboard Support

Enable this if you are using a USB keyboard.

BIOS SETUP

36 IB780 User’s Manual

OnChip Sound

This field enables or disables the on board audio function.

CPU to PCI Write Buffer

This controls the CPU write buffer to the PCI bus. If this buffer is
disabled, the CPU writes directly to the PCI bus. The default setting is
Enabled.

PCI Dynamic Bursting

This option controls the PCI write buffer. If this is enabled, then every
write transaction on the PCI bus goes straight to the write buffer. Burst
transactions are then sent on their way as soon as there are enough to
send in a single burst.

PCI Master 0 WS Write

This function determines whether there's a delay before any writes to the
PCI bus. If this is enabled, then writes to the PCI bus are executed
immediately (with zero wait states), as soon as the PCI bus is ready to
receive data. But if it is disabled, then every write transaction to the PCI
bus is delayed by one wait state. It's recommended to enable this for
faster PCI performance.

PCI#2 Access #1 Retry

This BIOS feature is linked to the CPU to PCI Write Buffer. Normally,
the CPU to PCI Write Buffer is enabled. All writes to the PCI bus are, as
such, immediately written into the buffer, instead of the PCI bus. This
frees up the CPU from waiting till the PCI bus is free. The data are then
written to the PCI bus when the next PCI bus cycle starts.

There's a possibility that the buffer write to the PCI bus may fail. When
that happens, this BIOS option determines if the buffer write should be
reattempted or sent back for arbitration. If this BIOS option is enabled,
then the buffer will attempt to write to the PCI bus until successful. If
disabled, the buffer will flush its contents and register the transaction as
failed. The CPU will have to write again to the write buffer.

AGP Master 1 WS Write/Read

When enabled a single wait state is used when writing/reading to the
AGP bus. When disabled a 2 wait state is used. For optimal performance
set this to enabled. For improved stability set it to disabled.
