AR-B1375/AR-B1376 User s Guide

System Keyboard

This function specifies that a keyboard is attached to the computer.

Primary Display

The option is used to set the type of video display card installed in the system.

Password Check

This option enables password checking every time the computer is powered on or every time the BIOS Setup is executed. If Always is chosen, a user password prompt appears every time the computer is turned on. If Setup is chosen, the password prompt appears if the BIOS executed.

Parity Check

Set this option to Enabled to check the parity of all system memory.

Wait for ‘F1’ If Error

AMIBIOS POST error messages are followed by:

Press <F1> to continue

If this option is set to Disabled, the AMIBIOS does not wait for you to press the <F1> key after an error message.

Hit ‘DEL’ Message Display

Set this option to Disabled to prevent the message as follows:

Hit ‘DEL’ if you want to run setup

It will prevent the message from appearing on the first BIOS screen when the computer boots.

Hard Disk Delay

If this option is set to Disabled, and the system BIOS executes too fast the result may be that the BIOS can’t find the hard disk drive. Use caution when setting this option.

On Board Flash Disk

This item is used to activate the FLASH on this CPU board.

Shadow

These options control the location of the contents of the 32KB of ROM beginning at the specified memory location. If no adapter ROM is using the named ROM area, this area is made available to the local bus. The settings are:

SETTING

DESCRIPTION

Disabled

The video ROM is not copied to RAM. The contents of

 

the video ROM cannot be read from or written to cache

 

memory.

Enabled

The contents of C000h - C7FFFh are written to the same

 

address in system memory (RAM) for faster execution.

Cached

The contents of the named ROM area are written to the

 

same address in system memory (RAM) for faster

 

execution, if an adapter ROM will be using the named

 

ROM area. Also, the contents of the RAM area can be

 

read from and written to cache memory.
