Gate A20 Option
This entry allows you to select how the gate A20 is handled. The gate
A20 is a device used for above 1MByte of address memory. Initially, the
gate A20 was handled via a pin on the keyboard. Today, while a key-
board still provides this support, it is more common and much faster in
setting to Fast for the system chipset to provide support for gate A20.
Ø The choice: Normal or Fast.
Typematic Rate Setting
Keystrokes repeat at a rate determined by the keyboard controller.
When this controller enabled, the typematic rate and typematic delay
can be selected.
Ø The choice: Enabled or Disabled.
Typematic Rate (Chars/Sec)
This item sets how many times the keystroke will be repented in a
second when you hold the key down.
Ø The choice: 6, 8, 10, 12, 15, 20, 24 or 30.
Typematic Delay (Msec)

Security Option
Select whether the password is required every time the system boots or
only when you enter setup.
