Introduction
Welcome to the PSB-810EAV Pentium® III, Celeron Single
Board Computer. The PSB-810EAV board is a PCI form factor
board, which comes equipped with high performance Pentium®
III, Celeron™,VIA Cyrix®ⅢProcessor and advanced high
performance multi-mode I/O, designed for the system
manufacturers, integrators, or VARs that want to provide all
the performance, reliability, and quality at a reasonable price.
In addition, the PSB-810EAV provides on chip VGA. The VGA
which provides up to 1600x1200 resolution. The VGA memory
is share main memory.
An advanced high performance super AT I/O chip – ITE IT8712
is used in the PSB-810EAV board. Both on-chip UARTs are
compatible with the NS16C550. The parallel port and IDE
interface are compatible with IBM PC/AT architecture's.
PSB-810EAV uses Intel 82559 Fast Ethernet Multifunction PCI
Controller as LAN controller. The 82559 is a fully integrated
10BASE-T/100BASE-TX LAN solution with high performance
networking functions and low power features.
PSB-810EAV uses the advanced INTEL Chipset,810E
which is 100% LPC/PCI software compatible chipset.with PCI
2.2 standard.

BIOS Setup
4.1 Introduction
This chapter discusses the Setup program built into the BIOS. The
Setup program allows users to configure the system. This
configuration is then stored in battery-backed CMOS RAM so that it
retains the Setup 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 system on, or
2. by pressing the <Del> key when the following message appears
briefly at the bottom of the screen during the 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
4.3 Using Setup
22
In general, you can use the arrow keys to highlight items, press
<Enter> to select, use the PageUp and PageDown keys to change
entries, press <F1> for help and press <Esc> to quit. The following
table provides more details about how to navigate in the Setup program
using the keyboard.

23
Once you enter the AwardBIOS™ CMOS Setup Utility, the Main Menu
will appear on the screen. The Main Menu allows you to select from
several setup functions and two exit choices. Use the arrow keys to
select among the items and press <Enter> to accept and enter the
sub-menu.

↑↓←→Move Enter: Select +/-/PU/PD: Value F10:Save ESC: Exit
F1:General Help
F5:Previous Values F6:Fail-safe defaults F7:Optimized Defaults
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.

37
DRAM Settings
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.
SDRAM CAS Latency Time
When synchronous DRAM is installed, the number of clock cycles of
CAS latency depends on the DRAM timing.
The Choice: 2, 3
SDRAM Cycle Time Tras/Trc
Select the number of SCLKs for an access cycle.
The Choice: 5/7, 6/8.
SDRAM 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.
SDRAM RAS Precharge Time
38
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.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-
FFFFFh, resulting in better system performance. However, if any
program writes to this memory area, a system error may result.
The choice: Enabled, Disabled.
Video BIOS Cacheable
Select Enabled allows caching of the video BIOS , resulting in better
system performance. However, if any program writes to this memory
area, a system error may result.
The Choice: Enabled, Disabled.
Memory Hole At 15M-16M
You can reserve this area of system memory for ISA adapter ROM.
When this area is reserved, it cannot be cached. The user information
of peripherals that need to use this area of system memory usually
discusses their memory requirements.
The Choice: Enabled, Disabled.
CPU Latency Timer
Enabled :CPU cycle will only be Deferred after in has been in a “Snoop
Stall” for 31 clocks and another ADS# has arrived.
Disabled: CPU cycle will only be Deferred immediately after the GMCH
receives another ADS#.

39
The Choice: Enabled, Disabled.
Delay Transaction
The chipset has an embedded 32-bit posted write buffer to support
delay transactions cycles. Select Enabled to support compliance with
PCI specification version 2.1.
The Choice: Enabled, Disabled.
Onboard VGA
This item controls the Onaboard VGA to enabled or disabled.
The Choice: Enabled, Disabled.
Power-Supply Type
This item controls the power-supply type to AT or ATX.
The Choice: AT,ATX.
