Removing BIOS Passwords:
If you key in the wrong Supervisor password three times, an error code is generated and system is disabled.
To unlock the BIOS, perform the following steps:
1. On a different machine, run the BIOS_PW.EXE file along with the error code generated. For example:
bios_pw 14452 0
2. Four ASCII strings are generated as output. Select and note down any one of the strings.
3. Reboot the machine with the locked BIOS and then use either any of the strings as the BIOS user
password.
