your system and Setup Utility. Supervisor Password has higher
priority than User Password. Once you setup the password, the
system will always ask you to key-in password every time you
enter the BIOS SETUP. If you enter the BIOS SETUP with
Supervisor Password, you can choose every setup/option on the
main menu but with User Password, you can only choose three
setup/options (USER PASSWORD, SAVE & EXIT SETUP and EXIT
WITHOUT SAVING). To disable these passwords, enter the
BIOS SETUP room with Supervisor Password and then just
press the <Enter> key instead of entering a new password
when the 'Enter Password' prompt pop-up.
Note: If you forget the password, do the Clear/Reset CMOS
procedure (see Section 2.5 Clear CMOS Setup)

Chapter 5. SVGA Setup
5.1 Introduction
The WAFER-5823 is equipped with on-board VGA interface. The
description below is its specifications and features:
5.1.1 Chipset
The WAFER-5823 uses a NS CX5530A chipset as its SVGA
controller. It is compatible with many common 18-bit LCD
displays and traditional analog CRT monitors. VGA BIOS
supports LCD. Besides, it also accepts interlaced and
non-interlaced analog monitors (color and monochrome VGA)
with high-resolution quality while maintaining complete IBM
VGA compatibility. But digital monitors (i.e. MDA, CGA, and EGA)
can be NOT supported. Multiple frequency (multisync) monitors
are operated as if they were analog monitors.
5.1.2 Display memory
Having 1.5 ~ 4 MB UMA memory, the VGA controller can make
CRT displays or color panel displays perform with resolutions up
to 1024 x 768 at 64 K colors. The display memory can be
modified up to 4 MB in BIOS for true-color resolution of 1024 x
768.
5.1.3 Display drivers
1. Win95, 98 drivers (VGA) in CD rom
\ Vga \ MediaGX \ Win9x
2. WinNT4.0 drivers in CD rom
\ Vga \ MediaGX \ Nt40

Chapter 6.
PCI Bus Ethernet Interface
The WAFER-5823 provides three high performance 32-bit
Ethernet chipset that is completely compliant with IEEE 802.3
100 Mbps CSMA/CD standards. It is both 100Base-T and
10Base-T compatible. The major network operating system fits
it. The medium type can be set up via the RSET8139.exe
program included on the utility CD.
The Ethernet port provides three standard RJ-45 connectors on
board. To utilize the network boot feature, please incorporate
the boot ROM image files for the appropriate network operating
system. Boot ROM BIOS files are combined into system BIOS,
which can be enabled/disabled through BIOS setup Menu.
The 8139x utility tools are in the following directory of CD rom\
Lan \ Realtek \ 8139c \

Appendix A. Watchdog Timer
The Watchdog Timer is a device 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
normally, hardware on the board will perform hardware reset
(cold boot) to bring the system back to a known state.
Three I/O ports control the Watchdog Timer.
443 Write
443 (hex) Read
043/843 (hex) Read
Prior to enable the Watchdog Timer, user has to define Timer
first. The output data is a value of time interval and the range
of the value is from 01(hex) to FF (hex) and time interval 1 sec
to 255 sec.
Data Time Interval
01 1 sec
02 2 sec
03 3 sec
04 4 sec
.
.
.
FF 255 sec
Set Watchdog Time period
Enable the refresh the Watchdog
Timer
Disable the Watchdog Timer
.
.
.
45
This will enable and activate the countdown timer which will
eventually time out and reset the CPU to ensure that this reset
condition does not occur, the Watch-Dog Timer must be
periodically refreshed by reading the same I/O port 043/843H
and 443H. This must be done within the time out period that is
selected by software, please refer to the example program.
A tolerance of at least 5% must be maintained to avoid
unknown routines within the operating system (DOS), such as
disk I/O that can be very time consuming. Therefore if the
time-out period has been set to 10 seconds, the I/O port 443H
must be read within 7 seconds.
Note: When exiting a program it is necessary to disable the
Watchdog Timer, ot herwise the system will reset.
Example Assembly Program:
TIMER_PORT = 443H
TIMER_START = 443H
TIMER_STOP = 843H
