    Hello all,

    I'm in a bit of a bind. I'm working on a computer that needs the boot order changed, so I can install an OS upgrade (2000 to XP Pro) and I can't get into the BIOS without the supervisor password. The individual who had/worked on the computer before has long gone, so that option is out. The default stuff won't work (admin, exec, password...and so on). I seem to remember that you can dislodge the battery, or switch the jumpers (although different motherboards might have different stuff), but It's been several years since I've had this problem and I can't remember the solution.

    Any and all help would be appreciated.

    Not quite sure that'll be crackable. It'll depend on the mobo.

    Open up the case and remove the battery for about 5 minutes then replace it .
    this will clear the cmos and restore everything to it's default

    there will be no password to get into the bios after you put the battery back in.

    the battery looks like a watch battery only bigger (about the size of a quarter)

    Just clear cmos. You can do this with the clear cmos jumper or by removing the battery. Either way remove the power cord [to remove all power] press the power button [to remove residual charge from ps capacitors] Now pull the side cover and move the jumper to the clear position. This will take 15-30 seconds to clear cmos. When you have finished, you will need to enter the bios and make sure settings are correct. When you do this it reverts to defaults.
