SYSTEM BIOS SETUP
TOP
==================================================
After you have configured
the system board and assembled all the components, you need to enter the system
configuration information to the system BIOS through the AMI WinBIOS Setup programs. This
AMI WinBIOS Setup program and the system configuration information are embedded in the
system board and it is backup by the on-board battery. This system board is equipped with
the latest AMI WinBIOS for easy configuration with either the keyboard or mouse to pick
and change your options.
ENTERING
BIOS SETUP PROGRAM
TOP
==================================================
Turn on or Reboot the
system. After the system finished testing the on-board memory, the message "Hit DEL
if you want to run SETUP" will appear. Press "DEL" key at this time will
bring you into the BIOS Setup program.
Use keyboard "Tab" key
to choose different group windows, "Arrow" keys to high-light items, and use the
"Enter" key to select option or you may use the mouse to "Click" on
item you want to select and change. Press "ALT + H" keys will bring up the Help
Screen.
After the BIOS Setup program in
entered, you may want to do choose the "Standard" icon in the "SETUP"
group window for date, time, and all disk drives information. If you have IDE Hard
Drive(s) installed, the "Detect C" and "Detect D" icons in the
"Utility" group window can be use to automatically enter your hard drive(s)
information.
At any time you may press
"ESC" key to exit the window, and choose the "Do not save and exit"
option to keep the original configuration.

==================================================
Date, and Time Options
If you would like to set Date, and Time option, move cursor to highlight the items and
use PgUp/PgDn to modify the data.
Hard Disk C & D Types
According to your actual equipment, you can select the type of hard disks for C, D, E,
& F from 'Not Installed' to type 46 for standard hard disks. As for type 47, user may
define by himself.
Floppy Drives A & B
According to your actual equipment, set floppy drive A & B whose five options are
as highlighted.
LOAD BIOS
AND SETUP DEFAULTS
TOP
==================================================
There are three sets of BIOS
values stored in the ROM files :
The
"Original" default values
The "Optimal" default values
The "Fail-Save" default values
The "Original" default
values are those original options you have changed in the current session. You may use
this option to restore the original values you changed in the current session if you
changed your mind before they are saved. Once the changes are saved, this option does not
restore the original values.
The "Optimal" default
values are those settings which should provide optimum performance for the system. They
are the best case default values.
The "Fail-Save"
default values, which are the most conservative case defaults, but also are the most
stable default values for the system. They are to be used if the system is performing
erratically because of the hardware problems.
ADVANCED
SETUP
TOP
==================================================
Typematic Rate
Programming
By enabling this option, the user can select the rate at which a keystroke is repeated
by adjusting options "Typematic Rate Delay" and "Typematic Rate".
Typematic Rate Delay &
Typematic Rate
When a key is pressed and held down, the character appears on the screen and after a
delay set by the "Typematic Rate Delay", it keeps on repeating at a rate set by
the "Typematic Rate" value. Usually, these options are adjusted for Network,
OS/2 or other similar type of operating system when keyboard reaction become comparatively
slow. By using these options, the typematic rate can be adjusted to suit individual
preference.
System Keyboard
When keyboard is installed, POST routine test keyboard; otherwise, it does not.
Primary Display
Select the primary display. If you chose "Not Install", the system will
ignore the primary display while doing the POST test.
Extended BIOS RAM Area
The AMI BIOS Setup features one user-definable hard disk type. Normally, the data for
these disk types are stored at the 0:300 in the lower system RAM.
If a problem occurs with
software like Netware or OS/2 or similar that uses lower system RAM, this data can be
loaded at the upper limit of the DOS shell (640K). If the option is set to DOS 1K, the DOS
memory is shortened to 639KB, and the top 1KB is used for the hard disk type storage.
Floppy Drive Seek at Boot
You may set this option to "Disabled" to allow a fast boot and to reduce the
possibility of damage to the drives' heads.
System Boot Up Sequence
The system may be set to seek the operating system during power up either from the
floppy drive A: or from the hard drive C: by using this option.
External & Internal Cache
Memory
These options allows user to enable or disable the on-board (External) and the
on-chip(Internal) cache memories (SRAM) when special peripheral or software implemented
indicate such requirement. System over all speed will slow down considerably if these
options are disabled.
Password Checking
This option allow a password be set up so that a password will be needed to enter the
CMOS Setup or to boot the system including entering CMOS Setup. After this option is
enabled, you must use the PASSWORD icon in the security group to setup your password. If
in any case the password is lost or forgotten, the jumper JP 1 - Clear CMOS can be used to
clear the configuration.
WARNING - "JP 1" will
clear and reset ALL and EVERY configuration parameters. Make sure you know what you are
doing or ask someone who do to help you.
Virus Warning
This function, If enabled, will detects boot sector viruses and warning will be given
when a program attempted to change boot sector information.
Video & Adapter ROM
Shadows
Video and/or adapters ROM shadowing is a procedure in which BIOS codes from
peripheral(s) adapter(s) ROM when present are copied from slower ROM to faster RAM. The
BIOS are then executed from the faster RAM. Each option allows for a segment of 16 KB to
be shadowed from ROM to RAM. If one of these options is enabled, and there is BIOS present
in that particular 16 KB segment, the BIOS will be shadowed.
Video Shadow Before Video
Init
Enabling this option may speed up the boot up process. This option may be disabled if
video problem is encountered and it should not have any impact on the system performance
after boot-up.
CHIPSET
FEATURES SETUP
TOP
==================================================
Most of the options in this
group have major influence to the system. If options are not set properly, it may not only
the performance will be greatly affected, but also it may bring the system down
unexpectedly in most cases. Therefore, it is only wise to leave the defaults alone unless
there are specific reason to do any change.
Auto Config Functions
When this item is enabled, the system BIOS will detects CPU type and board frequency
and automatically set the option on the items indicated below to the optimum setting. The
system will ignores the setting entered manually. If this option is disabled, the items
below it must be set manually according to CPU type and speed. The following table is the
auto-configuration default settings for the different operation frequency.
Cache Read Hit Wait State
This option allows you to choose the cache read operation mode during burst read. The
3-1-1-1 can be used for 33MHz system or less with 2 banks of cache memory installed. The
3-2-2-2 should be used for system faster then 33MHz or only one bank of cache installed.
Cache Write Hit Wait State
The 0 can be used for 33MHz system or less with 2 banks of cache memory installed. The
1 should be used for system faster then 33MHz or only one bank of cache installed.
DRAM Wait State Select
The 1 can be used for 33MHz system or less. The 2 should be used for system faster
then 33MHz.
DRAM Page Mode
Select "Fast" for this option if the SIMM modules installed support Fast
Page Mode.
Keyboard Clock Select
The Keyboard Clock should be maintain at around 8MHz to conform to the AT standard.
AT Bus Clock
The AT bus clock should be maintain at around 8MHz to conform to the AT standard.
Alt Bit in Tag SRAM
The default "7+1" setting would give better performance and should always
set as such.
Local Ready Delay Setting
Local Bus Setting, unless otherwise required, do not change the default setting.
Signal LDEV# Sample Time
Local Bus Setting, unless otherwise required, do not change the default setting.
CPU ADS# Delay 1T or Not
Local Bus Setting, unless otherwise required, do not change the default setting.
ISA Bus Refresh Disable Bit
"Fast" setting provide better performance.
Divider for Refresh
Memory refresh setting, unless otherwise required, do not change the default setting.
System Memory Remap or Not
Enabled this option will allow the system to remap the unused upper memory to the
extended addresses.
Video, Adapter & System
ROMs Cache
The video, adapter and system shadows can also be cached for improved performance.
Low A20# Select, & RC
Reset Select
The Gate A20 and the Real Time Clock should always be set to "Chipset" for
better performance under protected mode operation.
IO Recovery Time
AT Bus I/O Recovery Time, unless otherwise required, do not change the default
setting.
POWER
MANAGEMENT SETUP
TOP
==================================================
This system board is
designed to fully support the SMM/SMI power management protocol. When the Power Management
Mode option is enabled, the system will enter into Standby and then suspend (inactive)
mode after the length of time set at the Timer options when no system activities are
detected.
IDE Standby Power Down Mode
This option is a BIOS's built-in function that does not require SMI to operate,
however, if this option is enabled and you experience erratic hard drive behavior, this
option must be disabled. It means that your hard disk does not support this BIOS function
Power Management Mode Select
This option served as a master switch to turn-on the power management mode.
Standby Timer Value
This is the first stage when the system entered into the power management mode. You
select the number of minutes after which the system will enter the power saving Standby
Mode when no activities as defined under the monitors options listed below are detected.
You may also use the option "Clock Out On Standby Mode" to select the specific
system speed in this mode.
Inactive Timer Value
This is the second stage when the system entered into the power management mode. You
select the number of minutes after which the system will enter the power saving
Inactive(Suspend) Mode when no activities as defined under the monitors options listed
below are detected. This mode only function if a SL-Enhanced CPU is installed, since only
a SL-Enhanced CPU can support Stop-Clock (0 MHz) operation.
Sampling Activity Delay,
& SMI Pulse Width
Unless otherwise required, do not change the default setting.
Monitor ... Port Activity
These options allow you to specify what activities the system should monitor which
will either prevent the system from enter into power saving mode or wake-up the system
from power saving mode when activity is detected as defined in here.
Suspend / Resume Switch
If this option is enabled, you may use the JP23 to force the system into Inactive Mode
immediately.
Clock Out On Standby Mode
Define the system speed after the system entered into Standby Mode. The PCLK equal to
the CPU Clock - if you are using DX2-66MHz, you CPU CLK is 33MHz, setting this option to
"PCLK/4" make the Standby Mode clock to 8MHz.
VGA Power Control
The "Normal" setting will work for most of the VESA compliance VGA
controllers. This option will enable the system to blank the monitor screen when power
saving mode is entered.
IDE Power Control
The IDE Power Control supports hard drive that has such a feature, however, if this
option is enabled and you experience erratic hard drive behavior, this option must be
disabled. This option uses the SMM/SMI specification for hard drive power saving control.
APM Function
APM Function allows application that uses Advance Power Management interface to
control the system power management features when the system is installed with a
SL-enhanced CPU.

==================================================
At this point, you can
either choose to confirm your setup entries and exit by using "ESC" key and
taking the "Save Changes & Exit" or the "Do Not Save & Exit"
option to restore the original setup parameters and exit.
After you highlight the desired
option and press <<ENTER>>, the system will reset itself. The new or original
setup parameters, depend on the option which you have chosen, will become the current
setting.
KEYBOARD
TURBO SWITCH
TOP
==================================================
After booting the system,
you can select processor clock speed (Turbo or non-Turbo) by using keyboard command in
addition to use the front-panel switch.
Your system board has speed
switching circuitry allowing it to change speed during operation, even while you are
running a program. To change the processor speed, use the following keyboard combinations
: High Speed : <Ctrl> + <Alt> + <+> Low Speed : <Ctrl> +
<Alt> + < - > |
