Password Protection
The BIOS uses passwords to prevent unauthorized tampering with the system. Once a password is
set up, access to BIOS setup is allowed only after the correct password(s) has been entered. Both
user and supervisor passwords are supported by the BIOS. The user password cannot be set unless
a supervisor password has been set.
When set, a password can be cleared by changing it to a null string. Clearing the supervisor password
also clears the user password. Entering the user password permits modification of the time, date,
language, user password, and password on boot setup fields; other setup fields can be modified only
if the supervisor password is entered. The user password also allows the system to boot, if secure
boot is enabled.
If a wrong password is entered three times in a row, the BIOS stops validating passwords and the
BIOS security engine returns a failure for any further password validation attempt. If the user enters
three wrong passwords in a row during the boot sequence (i.e., when entering Setup), the system is
placed into a halt state. This feature makes is difficult to break the password by the “trial and error”
method.
Using Passwords
If only the supervisor password is set, you:
• Must enter the supervisor password to enter BIOS Setup.
• Must enter the supervisor password to boot the Workstation if Password on Boot is
enabled in the BIOS Setup.
If both passwords are set, you:
• May enter the user password to enter BIOS Setup. However, you will not be able to
change many of the options.
• Must enter the supervisor password if you want to enter BIOS Setup and have access to
all of the options.
• May enter either password to boot the Workstation if Password on Boot is enabled in the
BIOS Setup.
• May enter either password to exit secure mode.
Password Clear Jumper
If the user or supervisor password(s) is (are) lost or forgotten, moving the password clear jumper into
the “clear” position clears both passwords. The password clear jumper must be restored to its original
position before a new password(s) can be set. The password clear jumper is located on jumper block
J4A1 pins 1-2 on the mainboard.
Floppy Write Protection
When selected in BIOS Setup, the floppy write protection option blocks writes to the floppy disk
when the system is in secure mode. Floppy write protection is in effect only while the system is in
secure mode. When not in secure mode, write protection is disabled and the floppy diskette drive
operates normally.
