Chapter 1 Introduction
SAGP-865EVG is an AGP/PCI form factor board to work with
a high performance processor. It is equipped with advanced
high performance multi-mode I/O and designed for the
system manufacturers, integrators, or VARs who want to
provide all the performance, reliability, and quality at a
reasonable price.
Its AGP interface supports 0.8V/1.5V signaling with 8X/4X
data transferring, but it does not support any AGP-card of
3.3V. The integrated graphics controller provides 3D, 2D,
and display capabilities.
SAGP-865EVG supports one or two 64-bit wide DDR data
channels. The available bandwidth is up to 2.7GB/s for
single-channel mode and 5.4GB/s for dual-channel mode.
The CSA interface connects to the GMCH with a Gigabit
Ethernet controller.
The built-in ICH5 provides 10/100 Fast Ethernet LAN
connection. It’s a fully integrated 10BASE-T/100BASE-TX
LAN solution with high performance networking functions and
low power consumption.
For the application that needs high speed serial transmission,
the SAGP-865EVG provides USB2.0 for an alternative choice.
The high speed USB2.0 host controller implements an ECHI
interface that provides 480Mb/s bandwidth.
This PIAGP CPU card must be installed on PCIAGP/PXAGP
series backplanes made by IEI. If onboard ISA interface is
required, please be sure to install PISA-KIT01 daughter
board on the specific socket on the backplane before ISA
cards are installed so the system can work properly.

Chapter 4 Award BIOS Setup
4.1 Introduction
This chapter discusses the Setup program written in the
BIOS. It will give you a step-by-step guidance to configure
your system. The user-defined configuration is then stored
in battery-backed CMOS RAM, which retains the customized
information while the power is off.
4.2 Starting Setup
The BIOS is immediately active when you turn on the
computer. While the BIOS is in control, the Setup program
can be activated in one of two ways:
1. By pressing <Del> immediately after switching the

2. By pressing the <Del> key when the following message
appears at the bottom of the screen during POST (Power
On Self-Test):
Press DEL to enter SETUP
If the message disappears before you respond and you still
wish to enter Setup, restart the system to try again by
turning it OFF then ON or pressing the "RESET" button on
the system case. You may also restart by simultaneously
pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not
press the keys at the correct time and the system does not
boot, an error message will be displayed and you will again
be asked to...
PRESS F1 TO CONTINUE, DEL TO ENTER SETUP
22
4.3 Using Setup
In general, you can use the arrow keys to highlight items,
press <Enter> to select, use the PageUp and PageDown keys

4.7 Advanced Chipset Features
This section allows you to configure the system based on the
specific features of the installed chipset. This chipset
manages bus speeds and access to system memory
resources, such as DRAM and the external cache. It also
coordinates communications between the conventional ISA
bus and the 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.
DRAM Timing Selectable
The first chipset settings deal with CPU access to dynamic
random access memory (DRAM). The default timings have
been carefully chosen and should only be altered if data is
being lost. Such a scenario might well occur if your system
had mixed speed DRAM chips installed so that greater delays
may be required to preserve the integrity of the data held in
the slower memory chips.
34
CAS Latency Time
When synchronous DRAM is installed, the number of clock
cycles of CAS latency depends on the DRAM timing.
The Choice: 1.5 , 2, 2.5 , 3
DRAM RAS# to CAS# Delay
This field lets you insert a timing delay between the CAS and
RAS strobe signals, used when DRAM is written to, read from,
or refreshed. Fast gives faster performance; and Slow gives
more stable performance. This field applies only when
synchronous DRAM is installed in the system.
The Choice: 2, 3.
DRAM RAS# Precharge
If an insufficient number of cycles is allowed for the RAS to
accumulate its charge before DRAM refresh, the refresh may
be incomplete and the DRAM may fail to retain data. Fast
gives faster performance; and Slow gives more stable
performance. This field applies only when synchronous
DRAM is installed in the system.
The Choice: 2, 3.
DRAM Frequency For
This field displays the capability of the memory modules that
you are using either H/W TRAP.
The Choice: Auto, DDR266, DDR333, DDR400.

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 password will be
required both at boot and at entry to Setup. If set to
“Setup”, prompting only occurs when trying to enter Setup.
51
4.16 Exit Selecting
Save & Exit Setup
Pressing <Enter> on this item asks for confirmation:
Save to CMOS and EXIT (Y/N)? Y
Pressing “Y” stores the selections made in the menus in
CMOS – a special section of memory that stays on after you
turn your system off. The next time you boot your computer,
the BIOS configures your system according to the Setup
selections stored in CMOS. After saving the values the
system is restarted again.
Exit Without Saving
Pressing <Enter> on this item asks for confirmation:
Quit without saving (Y/N)? Y
This allows you to exit Setup without storing in CMOS any
change. The previous selections remain in effect. This exits
the Setup utility and restarts your computer.
52
Appendix A. Watchdog Timer
The Watchdog Timer is provided to ensure that standalone
systems can always recover from catastrophic conditions that
cause the CPU to crash. This condition may have occurred by
external EMI or a software bug. When the CPU stops working
correctly, hardware on the board will either perform a
hardware reset (cold boot) or a Non-Maskable Interrupt (NMI)
to bring the system back to a known state.
A BIOS function call (INT 15H) is used to control the
Watchdog Timer:
INT 15H:
AH – 6FH
Sub-function:
AL – 2 : Set the Watchdog Timer’s period
BL : Time-out value(Its unit--second or minute, is
dependent on the item “Watchdog Timer unit
select” in CMOS setup).
You have to call sub-function 2 to set the time-out period of
Watchdog Timer first. If the time-out value is not zero, the
Watchdog Timer will start counting down. While the timer
value reaches zero, the system will reset. To ensure that this
reset condition does not occur, the Watchdog Timer must be
periodically refreshed by calling sub-function 2. However the
Watchdog timer will be disabled if you set the time-out value
to be zero.
A tolerance of at least 10% must be maintained to
avoid unknown routines within the operating system
(DOS), such as disk I/O that can be very timeconsuming.
Note: When exiting a program it is necessary to disable the
Watchdog Timer, otherwise the system will reset.
53
Example program:

How to Upgrade a New BIOS
<Note> Before flashing BIOS , please enable the item
“FLASH BIOS” in BIOS setting.
You can install an upgrade BIOS for the SAGP-865EVG that
you can download from the manufacturer’s web site
( http://www.ieiworld.com
for new peripherals ,improvements in performance or fixes to
addressed known bugs.
BIOS Update Procedure:
1. Make a boot disk. Go to the DOS command prompt in
MS-DOS or Windows 9x and, with an available floppy disk
in "A", type "format A: /s" That will format the floppy
and transfer the needed system files to it.
NOTES:
A. This procedure will erase any prior data on that
floppy, so please Proceed accordingly.
B. Typically four files will be transferred, only
COMMAND.COM being visible when running a simple
directory listing.
C. Please leave the diskette UN-write protected for the
balance of this procedure.
). New BIOS may provide support
2. Download the BIOS upgrade file and awdflash.exe utility
from a ICP web site to a temp directory on your hard
drive, or directly to the floppy you made in step 1..
3. Copy ( BIOS file and awdflash.exe )two files to the boot
floppy.
4. Reboot the system to the DOS command prompt using
the boot diskette you just made.
5. At the DOS command prompt type , "awdflash
filename.xxx", where filename.xxx is the file name of the
BIOS file . Hit enter.
57
6. Your first option, in sequence, will be to save the old
BIOS. We recommend that you do that in case, for
whatever reason, you decide you don't wish to use the
new version once it is installed.
NOTES:
A. If you decide to save the old BIOS, PLEASE make
sure you do NOT save it to the same file name as
the new BIOS - if you use the same BIOS name the
old file will be written over the new file with NO
warning prompt. A simple file name to save the old
BIOS to is OLDBIOS.BIN.
B. If you do NOT decide to save the old BIOS, PLEASE
at least write down the version number of the old
BIOS and store that information with your important
computer documents. Enter N (for "no") and skip to
step 9.
7. To save the old BIOS, hit Y (for "yes")
8. Enter a name for the OLD BIOS file and hit enter.
NOTE: PLEASE be sure you do NOT save the old BIOS
file to the same file name as the new BIOS - if
you use the same BIOS name, the old file will
write over the new BIOS file WITHOUT a warning
prompt. A simple file name for saving the old
BIOS to is OLDBIOS.BIN.
9. Your second option, in sequence, will be whether you
want to flash your BIOS. Enter Y (for "yes").
NOTE: This is the critical step. Once you kit the enter
key, do NOT touch the keyboard, the reset
button, or power switch while the flashing is in
progress. There will be bar progressing across
the screen while the flashing is progressing.
10. When the flashing process is complete, you will be asked
to reset or power off the system. Remove the floppy
diskette from the floppy drive and either hit the reset
button or the power button.
11. Reboot the system and note that the BIOS version on the
initial boot-up screen has changed to the new BIOS
version. Your BIOS upgrade is now complete.
58
Recovering Your Old BIOS:
1. Assuming you have the floppy made during the
upgrade procedure noted above, boot the system
with that diskette in the floppy drive. If you do not
have floppy made during the upgrade procedure
noted above, you will need to repeat steps 1 though
3 (above) for the version of the BIOS you wish to
recover to.
2. Complete steps 4, 5, 6B, 9, 10, and 11 (above)
substituting the name of the BIOS you wish to
recover for the upgrade BIOS at step 5.
Install screen :

Appendix D. AGP slot
This IPC CPU Card has an Accelerated Graphics Port (AGP)
slot that supports +1.5V AGP card. When you buy an AGP
card, make sure that you ask for one with +1.5V
specification. Note the notches on the card golden fingers to
ensure that they fit the AGP slot on your ICP CPU card.
When SAGP-865EVG works with PCIAGP-4S or PCIAGP-5S
backplane, please do not connect to an external AGP-VGA
Card.
60
Appendix E.
Install Memory Modules
SAGP-865EVG has 2 dual in line memory module (DIMM)
sockets . The BIOS will automatically detects memory type
and size. To ins tall the memory module, just push it
vertically into the DIMM socket. The DIMM module can only
fit in one direction due to the notch. Memory size can vary
between sockets.
SAGP-865EVG supports the Dual Channel Technology. After
operating the Dual Channel Technology, the bandwidth of
Memory Bus will add double up to 6.4GB/s.
SAGP-865EVG includes 2 DIMM sockets, and each Channel
has one DIMM socket.
If you want to operate the Dual Channel Technology, please
note the following explanations due to the limitation of
Intel® chipset specifications.
1. Only one DDR memory module is installed: The Dual
Channel Technology can't operate when only one DDR
memory module is installed.
2. Two DDR memory modules are installed (the same
memory size and type): The Dual Channel Technology
will operate when two memory modules are inserted
individually into Channel A and B
