3IBAT User’s Manual
Disabled 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 360K.
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.
On Keypad is number keys
Off Keypad is arrow keys
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple
sector read/write. If your IDE hard drive supports block mode (most new
drives do), select Enabled for automatic detection of the optimal number
of block read/writes per sector the drive can support.
The choice: Enabled, Disabled.
Gate A20 Option
This entry allows you to select how the gate A20 is handled. The gate A20
is a device used to address memory above 1 Mbytes. Initially, the gate
A20 was handled via a pin on the keyboard. Today, while keyboards still
provide with this support, it is more common, and much faster, for the
system chipset to provide with the support gate A20.
Normal keyboard
Fast chipset
Memory Parity/ECC Check
This item allows you to Enable/Disable Memory Parity/ECC check.
The choice: Enabled/Disabled.
Typematic Rate Setting
This determines if the typematic rate is to be used. When disabled, con-
tinually holding down a key on your keyboard will generate only one
instance. In other words, the BIOS will only report that the key is down.
When the typematic rate is enabled, the BIOS will report as before, but it
will then wait a moment, and, if the key is still down, it will begin the report
that the key has been depressed repeatedly. For example, you would use
such a feature to accelerate cursor movements with the arrow keys.
Enabled Enable typematic rate
Disabled Disable typematic rate
