This is because OS/2 and Windows enter and leave pro-
tected mode via the BIOS, so Gate A20 needs to switch often
from enabled to disabled and back again. Setting this feature
to Fast improves memory access performance above 1MB
because the chipset is much faster at switching Gate A20
than the keyboard controller. It is recommended that you set
it to Fast for faster memory accesses. The choices are:
Normal / Fast
Typematic Rate Setting
This feature enables you to control the keystroke repeat rate
when you depress a key continuously. When enabled, you
can manually adjust the settings using the two typematic con-
trols (Typematic Rate and Typematic Delay). If disabled, the
BIOS will use the default setting. The choices are:
Enabled/Disable
Typematic Rate (Chars/Sec)
This setting defines the number of characters repeated per
second when holding down a key on the keyboard. The pos-
sible values are:
6 / 8 / 10 / 12 / 15 / 20 / 24 / 30
Typematic Delay (Msec)
This setting defines the delay (in milli-seconds) that occurs at
keystroke before the key will start to repeat. The possible val-
ues are:
250 / 500 / 750/ 1000
Security Option
Setting this option to System will set the BIOS to ask for the
password each time the system boots up.
If you choose Setup, then the password is only required for
access into the BIOS setup menus. The choices are:
Setup / System
