BIOS Setup
Swap Floppy Drive
When this field is enabled and the system is booting from the floppy
drive, the system will boot from drive B instead of drive A. When
this field is disabled and the system is booting from the floppy drive,
the system will boot from drive A. You must have two floppy drives
to use this function.
Boot Up Floppy Seek
When enabled, the BIOS will check whether the floppy disk drive in-
stalled is 40 or 80 tracks. Note that the BIOS cannot distinguish be-
tween 720K, 1.2M, 1.44M and 2.88M drive types as they are all 80
tracks. When disabled, the BIOS will not search for the type of floppy
disk drive by track number. Note that there will not be any warning
message if the drive installed is 360KB.
Boot Up NumLock Status
This allows you to determine the default state of the numeric
keypad. By default, the system boots up with NumLock on wherein
the function of the numeric keypad is the number keys. When set to
Off, the function of the numeric keypad is the arrow keys.
Gate A20 Option
This entry allows you to select how gate A20 is handled. Gate A20
is a device used to address memory above 1 Mbyte. Initially, gate A20
was handled via the keyboard controller. Today, while keyboards still
provide this support, it is more common, and much faster, for the sys-
tem chipset to provide support for gate A20.
