Other Boot Device
The BIOS attempts to load the operating system from
the devices in the sequence selected in these items.
The choice: Floppy, LS/ZIP, HDD, SCSI, CDROM,
Disabled.
Swap Floppy Drive
This field is effective only in systems with two floppy
drives. Selecting Enabled assigns physical drive B
logical drive A, and physical drive A to logical drive B.
Boot Up Floppy Seek
When enabled, the BIOS tests (seeks) floppy drives
to determine whether they have 40 or 80 tracks. Only
360-KB floppy drives have 40 tracks; drives with
270KB, 1.2MB, and 1.44MB capacity all have 80
tracks. Because very few modern PCs have 40-track
floppy drives, we recommend that you set this field to
a disabled to save time.
Boot Up NumLock
Status
Toggle between On or Off to control the state of the
NumLock key when the system boots. When toggled
On, the numeric keypad generates numbers instead
of controlling cursor operations.
Gate A20 Option
Gate A20 refers to the way the system addresses
memory above 1 MB (extended memory). When set
to
Fast
, the system chipset controls Gate A20. When
set to
Normal
, a pin in the keyboard controller con-
trols Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.
Typematic Rate Setting
When
Disabled
, the following two items (Typematic
Rate and Typematic Delay) are irrelevant. Keystroke
repeat at a rate determined by the keyboard control-
ler in your system.
When
Enabled
, you can select a typematic rate and
typematic delay.
