Killing the BIOS-Boot Password

If you have forgotten your BIOS Boot-Password, have a look into your mainboard manual, or after opening your PC, onto your mainboard. Many mainboards have a JUMPER or SWITCH to clear the CMOS. This Jumper is often named like: "RTC_CLEAR" , "CLEAR CMOS" , "CLRCMOS" , "CLRCMS". His position is often near by the mainboard battery.

Attention: All hardware settings (harddisk-, bootsequence,-...settings) will be deleted! At least, you have to re-insert them again.

If no Jumper exists, you can try to remove the Battery and wait some time before you insert it back into the Mainboard. (some time means: ~ 1-5 minutes, 24 hours or up to 1 year!). Another way is to "short circuit" the contacts of the replaced Battery, but if there are some Diodes behind the contacts, they could make trouble.

 

Killing the BIOS-Setup Password

If you can't enter the Setup of your BIOS, you need a DOS-Bootdisk and one of the following MS-DOS Files:

Filename	Sourcecode I	Sourcecode II
DEBUG.EXE	- o 70 2E  - o 71 FF  - Q	- o 70 17  - o 71 17  - Q
QBASIC.EXE	- 10 OUT &H70,17  - 20 OUT &H71,0	- 10 OUT &H70,&H17  - 20 OUT &H71,&H17

Start the file an insert the sourcecode line by line.
