PC REPAIR: BYPASS FORGOTTEN BIOS PASSWORD

Saturday, April 4, 2009

There are three options to bypass BIOS password. Listing below sorted from simple to complex way to reset your forgotten BIOS password.

1. Omnipotent Password
BIOS from different manufacturer, has their own omnipotent password. Both omnipotent password and password that users set are able to unlock the computer. Try the abbreviation of manufacturer or the character string which formed by the first letter of each word. May be it is the omnipotent password.

2. Discharge by Software
CMOS ROM can be discharged by software way. Then help you to solve the password problem. Follow these method, use the prompt “DEBUG”, all things to be easy.

Clear Award Password
C: \>DEBUG

- o 70 34
- o 71 34
- q
or
- o 70 11
- o 71 ff
- q

Clear AMI Bios Password
C: \>DEBUG
- o 70 16
- o 71 16
- q
or
- o 70 10
- o 71 0
- q

Note: the setup of CMOS BIOS will be erased during the discharge, so the computer is able to running until you reset it. If it is COMPAQ computer, you’d better get a floppy disk which save CMOS program first, then do the discharge, or else it is easy to discharge but hard to recover.

3. Hardware Jumper Discharge to CMOS BIOS
All the computers could discharge to CMOS BIOS by switch or jumper, and clear any prompt (system booting prompt, CMOS setup prompt, key lock prompt). There are examples for the particularity of CMOS of some Original packaging computer:
The discharge of COMPAQ and AST is finished by close/open the switch, but except the state power off, follow these steps:

a. After the external power is turned off, push SW1 and SW1-2 to “on”.
b. External power is turned on. Restart the computer.
c. Wait for 1to 5 minutes, turn off the computer.
d. Push SW1 and SW1-2 to “off”
e. Turn on the computer, enter CMOS setup to reset it.

Most of motherboard discharge to CMOS by jumper, and for the different board, the pin is different. During the discharge, read the user’s guide of motherboard first, if the state of CMOS discharge jumper pin is not included in it, to check that whether there are signs on the motherboard, such as “Exit Batter”, “Clean CMOS”, “CMOS ROM Reset”. If you find these sign, connect the pin of switch, or else, remove the battery.

There were really instances that we need to reset basic input/output system (BIOS) passwords. This list of ways were valuable.
