Floppy Drive Swap [Disabled]
This field allows you to reverse the hardware drive letter assignments of your floppy
disk drives. Available options: [Disabled] [Enabled]
Floppy Drive Seek [Disabled]
When enabled, the BIOS will seek the floppy disk drive to determine whether the
drive has 40 or 80 tracks. Floppy drives with 1.44MB have 80 tracks. You may leave
the default [Disabled] to save time if you are using 1.44MB floppy drives.
PS/2 Mouse Support [Enabled]
[Enabled] will reserve IRQ12 for the PS/2 Mouse. If disabled, IRQ12 will be re-
served for expansion cards.
Primary Display [VGA/EGA]
Set this field to the type of video display card installed in your system. Available
options: [Absent] [VGA/EGA] [CGA40x25] [CGA80x25] [Mono]
Password Check [Setup]
When set to [Always], everytime you start the system, the password set in the Secu-
rity menu is required. [Setup] requires you to enter the password only when you
want to access the BIOS Setup program. Available options: [Setup] [Always]
Boot to OS/2 > 64M [No]
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to set this field to [Yes]; otherwise leave this on the Setup default of [No].
Internal Cache [WriteBack]
Leave on default setting. [Disabled] turns off the CPU’s built-in level 1 cache. Avail-
able options: [Disabled] [WriteBack]
External Cache [WriteBack]
Leave on default setting. [Disabled] turns off the CPU’s external level 2 cache. Avail-
able options: [Disabled] [WriteBack]
L2 Cache ECC [TableDefault]
This function controls the ECC check capability in the CPU level 2 cache. Leave on
default setting. Available options: [Disabled] [TableDefault]
System BIOS Cacheable [Enabled]
This feature allows you to cache the system BIOS ROM at F0000h-FFFFFh.
C000, 32kShadow to DC00, 16k Shadow [Disabled]
These fields are used for shadowing other expansion card ROMs. If you install other
expansion cards with ROMs on them, you will need to know which addresses the
ROMs use to shadow them specifically. Shadowing a ROM reduces the memory
available between 640KB and 1024KB by the amount used for this purpose.
