BIOS Setup
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 keyboards still
provide this support, it is more common, and much faster, for the sys-
tem chipset to provide support for gate A20.
Typematic Rate Setting
Disabled Continually holding down a key on your keyboard will
cause the BIOS to report that the key is down.
Enabled The BIOS will not only report that the key is down,
but will first wait for a moment, and, if the key is still
down, it will begin to report that the key has been
depressed repeatedly. For example, you would use such
a feature to accelerate cursor movements with the ar-
row keys. You can then select the typematic rate and
typematic delay in the “Typematic Rate (Chars/Sec)”
and “Typematic Delay (Msec)” fields below.
Typematic Rate (Chars/Sec)
This field allows you to select the rate at which the keys are acceler-
ated.
Typematic Delay (Msec)
This field allows you to select the delay between when the key was
first depressed and when the acceleration begins.
Security Option
This field determines when the system will prompt for the password
- everytime the system boots or only when you enter the BIOS
setup. Set the password in the Set Supervisor/User Password
submenu.
System The system will not boot and access to Setup will be
denied unless the correct password is entered at the
prompt.
Setup The system will boot, but access to Setup will be denied
unless the correct password is entered at the prompt.
