Cant wipe BIOS password

[vidya]

hey someone put a password on my bios a while ago and I don't know what it is, I've full powered it down, taken out battery for 1min+, used the CMOS jumpers but it's still on there.

How can it be this persistent?

Take out the battery for 30 min and leave the jumper in the reset position while doing so. That should take care of it.
