4.10 ADVANCED CMOS SETUP MENU

This setup includes all of the advanced features in the system. The detail descriptions are specified as below

Quick Boot

When enabled, speeds up the booting procedure by shortening or skipping some check items during POST.

1st Boot Device

2nd Boot Device

3rd Boot Device

Try Other Boot Device

These items allow you to set the sequence of booting, i.e., which drive to search first for the operating system.

Or look for other drive (device) to search for an operating system.

Floppy Access Control

Hard Disk Access Control

These items allow you to set Floppy and Hard Disk access mode. You can set Floppy and Hard Disk full control.

Or make them read only.

S.M.A.R.T for Hard Disks

This allows you to activate the S.M.A.R.T. (Self-Monitoring Analysis & Reporting Technology) capability for the hard disks. S.M.A.R.T is a utility that monitors your disk status to predict hard disk failure. This gives you an opportunity to move data from a hard disk that is going to fail to a safe place before the hard disk becomes offline.

Boot Up Num-Lock

This item sets if the Num Lock key will be automatically activated after system startup.

Floppy Drive Swap

This feature allows you to exchange the drive names of the two floppy disk drives, if installed. Make sure that

Drive A and Drive B item in the “Standard CMOS Setup” menu are updated accordingly.

Floppy Drive Seek

This item sets if the system will verify if the floppy disk drive type is 40 or 80 track type during POST. The 360 KB diskette is 40 tracks while 720 KB, 1.2 MB and 1.44 MB are all 80 tracks.

PS/2 Mouse Support

This item enables or disables the IRQ12 for PS/2 mouse.

System Keyboard

This item sets if the system will verify PS/2 keyboard present.

Primary Display

This item sets if the system will verify graphic card present.

Password Check

This option enables the password checking when the system boots up or runs CMOS Setup. It only takes effect after setting Change Supervisor Password.

(1) Setup:

This option will force system to check password before running Setup if you have already entered the current user password in “Change User Password”. By that time, the system will be only able to boot

(2) but deny accessing Setup.

Always:

Password prompt appears every boot-up. The system will not boot and deny access

Setup with invalid password. The best way is to clear CMOS or try to reload BIOS Setup to boot up system.

Boot To OS/2

This item allows you to access the memory that is over 64 MB in OS/2

System BIOS Cacheable

Selecting enabled allows caching of the system BIOS ROM at F000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

Shadow Memory (from address C000~DFFF, 16K per segment)

Each of segments provides three options “Disabled”, “Enabled”, and “Cached” for faster adapter’s ROM execution.

However this shadow function is Chipset oriented and dependent on system hardware feature. In general, C000 and C800 will be allocated for VGA BIOS and set to Cached to get higher display performance by shadowing and caching feature. If user chooses Enabled setting, only BIOS shadow function is active.
