Security Option; Video Bios Shadow - Abit IT5E Series User Manual

Introduction of BIOS

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.
