Security Option; Video Bios Shadow - Abit AR5 User Manual

3-14

Security Option:

This option can be set to System or to Setup.
After you have created a password through PASSWORD SETTING, this
option will deny access to your system (System) or modification of
computer setup (BIOS Setup) by unauthorized users.
ä SYSTEM: When you choose System, a password is required each time
the computer boots up. If the correct password is not given, the system
will not start.
ä SETUP: When you choose Setup, a password is required only when
accessing the BIOS Setup. If you have not set a password in the
PASSWORD SETTING option, this option is not available.
Notice: Don' t forget your password. If you forget the password, you will
have to open the computer case and clear all information in the
CMOS before you can start up the system. But doing this, you
have to reset all the options you had set up before.
PCI /VGA Palette Snoop:
This option allows the BIOS to preview VGA Status, and to modify the
information delivered from the Feature Connector of the VGA card to the
MPEG Card. This option can solve the display inversion to black after you
have used the MPEG card.
OS Select For DRAM > 64MB:
When the system memory is bigger than 64MB, the communication method
between the BIOS and the operating system will differ from one operating
system to another. If you use OS/2, select OS2; if you choose another
operating system, select Non-OS2.

Video BIOS Shadow:

This option is used to define whether the BIOS on the video card uses
shadow feature or not. You should set this option to Enable, otherwise the
display performance of the system will greatly decrease.
