One characteristic of digital circuit is its fast respond
to high or low signal. This kind of respond is badly
needed for harsh and critical industrial operating
environment. That’s why we design 4-bit digital inputs
and 4-bit digital outputs on the WAFER-4823.

Digital Input and Output, generally, are control
signals. You can use these signals to control external
devices that needs On/Off circuit or TTL devices. The
register address is 340H.

4.3 Advanced CMOS Setup

The following screen will be displayed if you select
Advanced CMOS Setup:

You can change the value of each options by using
<PgUp> and <PgDn> key. The available values are
shown on the right screen.

Quick Boot Î Enabled: this will enable the BIOS to
boot quickly when you turn on your computer. The
BIOS will only check the first 1MB of the system
memory.

Quick Boot Î Disabled: the BIOS will test all system
memory when it boots up. It will spend about 40
seconds untill it receives a Ready signal from the HDD.
It will also wait for you to press the <Del> key or not.

31

1st, 2nd, 3rd Boot Device Î to define the device type

for booting after the routines check up completes. If
the 1st Boot Device fails, the BIOS will attempt to boot
from the 2nd or the 3rd device.

Try Other Boot Devices Î the BIOS will try to boot

from any other available device in the system if the
1st, 2nd and 3rd device fails to boot.

Floppy Access Control Î to define the read/write

access which is set when booting from a floppy drive.

Hard Disk Access Control Î to define the

read/write access which is set when booting from a
HDD.

S.M.A.R.T. for Hard Disks Î to allow BIOS to use

the System Management and Reporting Technologies
protocol for reporting server system information on a
network.

BootUp Num-Lock Î to turn on/off the Num-Lock

option on a enhanced keyboard when you boot. If you
turn it off, the arrow keys on the numeric keypad can
be used just as the other set of arrow keys on the
keyboard and vice versa.

PS/2 Mouse Support Î to testify whether or not a

PS/2 mouse is supported.

System Keyboard Î to testify whether or not a

keyboard is attached to the computer.

32

Primary Display Î to define the type of display

monitor of the system. The Absent option is for
network file servers.

Password Check Î to define if a password is
necessary or not for access to the system.

Boot to OS/2 Î if you run the OS/2 operating

system, this option must be set to yes.
System BIOS Cacheable Î to define whether or not

the memory segment FOOOH can be read from or
written to cache memory. Setting it Enabled will give
faster execution in your system.

XXXX, 16k Shadow Î ROM Shadow is a technique
in which BIOS code is copied from slower ROM to
faster RAM. If you enable it then the BIOS will be
executed form the RAM. Each option allows 16KB
segment to be shadowed to the RAM.

4.4 Advanced Chipset Setup

Note: do not change any value on this page unless

you understand well the impact of every value to your
system.

34

4.5 Peripheral Setup

When you enter the Peripheral Setup, the following
items are available for setting:

On-board IDE Î to define the on-board Integrated
Drive Electronics controller channel(s) to be used.
Available options are: Primary, Secondary and
Disabled.

On-board FDC Î The floppy disk drive controller can
be Enabled or Disabled by this item. When you do
not need floppy disk, the FDD controller can be
disabled. If you set it Auto, the BIOS will try to
enable any floppy drive controller on the ISA Bus.

Serial Port 1 Î The options are Disable, 3F8, 2F8,
3E8, 2E8 and Auto. You can set the I/O address of
the serial port 1 ( COMA) or disable it.

35

Serial Port2 Î The options are Disable, 3F8, 2F8,
3E8, 2E8 and Auto. You can set the I/O address of

the serial port 2 ( COMB) or disable it.

On-board Parallel Port Î The options are Auto,
Disable, 3BC, 378 or 278. You can set the I/O

address of the parallel port or disable it.

Parallel Port Mode Î WAFER-4823 provides EPP,
ECP, ECP/EPP, and SPP/BPP Mode. EPP passes

the parallel port to be used with devices which stick to
the EPP specification. The existing parallel port
signals will be used by EPP to provide asymmetric bi­directional data transfer driven by the host devices.
ECP passes the parallel port to be used with devices
which stick to the ECP specification.

Parallel Port IRQ Î to define the Interrupt Request
(IRQ) which is used by the parallel port.

Parallel Port DMA Channel Î to set the DMA
Channel used by the parallel port.

4.6 Auto-Detect Hard Disk

This option detects the parameters of an IDE hard
disk drive (HDD sector, cylinder, head, etc)
automatically and will put the parameters into the
Standard CMOS Setup screen. Up to 4 IDE drives can
be detected and the parameters will be listed in the
box. Press <Y> if you accept these parameters. Press
<N> to skip the next IDE drives.

36

Note: If your IDE HDD was formatted in previous
older system, incorrect parameters may be detected.
In this case, you need to enter the correct parameters
manually or low-level format the disk.

4.7 Change Supervisor Password

This option sets a password that is used to protect
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
SETTING AND EXIT 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 Part2.3 the CPU Setting for
WAFER-4823 >> Clear CMOS SETUP)

37

4.8 Auto Configuration with Optimal Settings

This option lets you load the Optimal default settings.
These settings are best-case values which will provide
the best performance. Whenever your CMOS RAM is
damaged, this Optimal settings will be loaded
automatically.

38

4.9 Auto Configuration with Fail Safe Settings

This option lets you load the Fail Safe default settings
when something happens to your computer so that it
cannot boot normally. These settings are not the most
optimal settings but are the most stable settings.

39

4.10 Save Settings and Exit

Select this option when you finish setting all the
parameters and want to save them into the CMOS.
Just simply press <Enter> key and all the
configuration changes will be saved.

40

4.11 Exit Without Saving

Select this option if you want to exit the Setup
without saving the changes that you made. Just
simply press <Enter> key and you will exit the BIOS
SETUP without saving the changes.

Appendix A

A.Watch-Dog 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.

Two I/O ports control the Watchdog Timer :.

443
(hex)

Read Enable to refresh the

Watchdog Timer.
043
(hex)

Read Disable the Watchdog Timer.

To enable the Watchdog Timer, a read from I/O port
443H must be performed. This will enable and
activate the countdown timer which will eventually
time-out and either reset the CPU or cause a NMI,
depending on the setting of JP3. To ensure that this
reset condition does not occur, the Watchdog Timer
must be periodically refreshed by reading the same
I/O port 443H. This must be done within the time-out
period that is selected by jumper group JP4.

A tolerance of at least 30% must be maintained to
avoid unknown routines within the operating system
(DOS), such as disk I/O that can be very time­consuming. Therefore, if the time out period has been

42

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, otherwise the
system will reset.
