wait before it starts repeating the keystroke.
Generally, using a short delay is useful for people who type quickly and don't like to
wait long for a keystroke to be repeated. On the other hand, a long delay is useful for
users who tend to press the keys longer while typing. This prevents the keyboard
controller from unnecessarily repeating keystrokes with such users.
Security Option
This BIOS feature controls the application of the BIOS' password protection. It will
only work once you have created a password through the
Password Setting
option in
the main BIOS screen.
Selecting the
System
option will force the BIOS to ask for the password every time
the system boots up.
If you choose
Setup
, then the password is only required for access to the BIOS. This
option is useful for system administrators or computer resellers who need to keep
novice users from messing around with the BIOS.

Video BIOS Shadow
This parameter, when enabled, turns on BIOS ROM shadowing for the block of
memory normally used for standard VGA video ROM code, which is C0000 to
C7FFF (32K). In short, it speeds up your system by copying the contents of your
video BIOS code from the slow ROM in which it resides into faster RAM.
The default for this setting depends on the particular system a great deal.. Enabling it
will increase performance. Disable it if it causes system problems, particularly those
related to the video subsystem.
Note:
On some systems the video BIOS shadow setting is named for the address
range the video BIOS occupies, C0000-C7FFFh, instead of being specifically called
"Video BIOS Shadow".
