Password protected BIOS

By jardinier ·
Someone gave me a Pentium 100 computer and I thought I would use it to run some old software, like Dr DOS, Windows 3.1 and or Windows 95.

BUT, the BIOS "Award Software" is password protected. While everything is working fine at the moment, I would need to get into BIOS to upgrade the computer.

Thanks Larryhyman and also rahulbsbs.

I will go with the backdoor passwords.

rahulbsbs, your suggestion of removing the battery was an option offered at the website given by Larry, but there were possible complications with this method.

Since you haven't closed this off Jules the easiest way is to remove the battery of look for a 3 pin Header with a Jumper in it over pins 1 & 2 and move that jumper to pins 2 - 3 to clear the BIOS. It will give you an error message on the reboot that will ask you to go into BIOS and all you need do is reset the Time & Date and maybe identify the drives if they are not set to Auto on the first BIOS page then exit saving the settings.

Of course make sure that the unit is unplugged at the time so you manage to clear the BIOS. If there is no Lithium Battery on the M'Board it has what was called a Smart Socket under the BIOS Chip which can be removed if you are extremely careful but it would honestly be easier to forget about this problem and try the back door options if that's the case. If you do need to lift the BIOS Chip make sure that you just lift it and not the socket under it as that is the Smart Socket which is battery backed so you need to remove the BIOS Chip from the Smart Socket. Tandy/**** Smith and Jaycar have IC removal tools that will enable you to remove the IC quite easily but you'll need to make sure that you insert it the same way when you replace it or you'll kill the BIOS Chip immediately.

Cheers

With power unplugged ( of course ), take cover off of machine and look over the motherboard for a silver battery that looks like a nickel. This battery is what keeps your BIOS settings LIVE.

Carefully/gently remove this battery and wait a minute or so...then put it back. This should clear the BIOS settings ( and password ).

When you boot the machine, you should be able to go into the bios without passwd.
