Introducing the BIOS
User’s Manual
3-11
Boot Other Device:
Two options are available: Disabled or Enabled. The default setting is Enabled. This setting allows the
BIOS to try to boot devices other than the three which are listed in the above First, Second and Third
Boot Devices. If you set to Disabled, the BIOS will boot from only the three kinds of boot devices that
are set above.
Swap Floppy Drive:
This item can be set as Disabled or Enabled. The default setting is Disabled. When this feature is enabled,
you don’t need to open the computer case to swap the position of floppy disk drive connectors. Drive A
can be set as drive B and drive B can be set as drive A.
Boot Up Floppy Seek:
Two options are available: Disabled or Enabled. The default setting is Enabled. When the computer boots
up, the BIOS detects if the system has a FDD or not. When this item is set to “Enabled”, if the BIOS
detects no floppy drive, it will display a floppy disk drive error message. If this item is disabled, the BIOS
will skip this test.
Boot Up NumLock Status:
! Off: At boot up, the Numeric Keypad is in cursor control mode.
! On: At boot up, the Numeric Keypad is in numeric mode. (Default Settings)
Gate A20 Option:
Two options are available: Normal or Fast. The default setting is Normal. 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 controls Gate A20. Setting Gate A20 to
Fast improves system speed, particularly with OS/2 and Windows.
Typematic Rate Setting:
This item allows you to adjust the keystroke repeat rate. When set to Enabled, you can set the two
keyboard typematic controls that follow (Typematic Rate and Typematic Delay). If this item is set to
Disabled, the BIOS will use the default setting. The default setting is Enabled.
