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.


STANDARD SETUP OPTION                                                                    TOP
==================================================
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.


PASSWORD SETTING                                                                                TOP
==================================================
Please refer to Section "Advance Setup", Subject "Password Checking" for detail information to setup password.


EXITING SETUP UTILITY                                                                          TOP
==================================================
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> + < - >
