BIOS Setup
3.1.2.7 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.
3.1.2.8 Boot Up Floppy Seek
When enabled, the BIOS will check whether the floppy disk drive
installed is 40 or 80 tracks. Note that the BIOS cannot distinguish
between 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.
3.1.2.9 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 ar-
row keys.
3.1.2.10 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 key-
boards still provide this suppor t, it is more common, and much
faster, for the system chipset to provide support for gate A20.
Fast
The chipset controls Gate A20.
Normal
A pin in the keyboard controller controls Gate A20.
