Hi everyone,
Just wondering if anyone could help with this.
I have recently got an old computer from my dads work to muck around with and perhaps give linux a go i dont know.
But i have encountered a problem. As i went to view/change the bios settings it asks me for a password. I do not have the password nor does dads work as it is an old redundant computer that doesnt get used. We have no real way of getting this password off anyone as no one knows what it is.
My question is, is there a way around this? Anything that will reset the bios or allow me to enter the once password protected area. Could i take the little battery out or something?

Awaiting any ideas you guys might have.
Thanks
