Make a copy of the original BIOS on a bootable floppy disk before setting
passwords. You will need to upload the BIOS file in case you erase the CMOS
RAM in the future.
A note about passwords
The BIOS Setup program allows you to specify passwords in the Boot menu. The passwords
control access to the BIOS during system startup. Passwords are not case sensitive, meaning,
passwords typed in either uppercase or lowercase letters are accepted. The BIOS Setup
program allows you to specify two different passwords: a Supervisor password and a User
password. If you did not set a Supervisor password, anyone can access the BIOS Setup
program. If you did, the Supervisor password is required to enter the BIOS Setup program and
to gain full access to the configuration fields.
Forgot the password?
If you forget your password, you can clear it by erasing the CMOS Real Time Clock (RTC)
RAM. The RAM data containing the password information is powered by the onboard button
cell battery. If you need to erase the CMOS RAM, unplug the all the power cables and remove
the button cell battery. Re-install the battery after about 2 seconds, then power up the system.
Refer to section "Jumpers - Clear RTC RAM" on how to erase the CMOS.
Boot Sector Virus Protection [Disabled]
This field allows you to set boot sector virus protection, ensuring a virus-free boot
sector. The system halts and displays a warning message when it detects a virus.
If this occurs, you can either allow the operation to continue or use a virus-free
bootable floppy disk to restart and investigate your system. Configuration options:
