BIOS question
This is just a random question that I had. When you run a computer w/o an OS for the first time, you enter BIOS and configure it. Where exactly is the BIOS "program" stored? The mobo? The hard drive? Where is it running from?
 Ahhh....the mysteries of life....

There is a chip on your motherboard usually near the battery that stores all this information.

Thanks. But, I still have a question, what is this battery you're talking about? Why would a motherboard need a battery? Doesn't it get its power from an outlet through the power supply? Or are you referring to a laptop that isn't plugged in?

A motherboard has a battery so it still can keep time and CMOS settings etc when and if the computer is removed from the power outlet. It is just a cirucular disk that I would say is about the size of a 2p coin, but unless you visited the UK recently you wouldn't know what size they are.

There is a little battery in the mobo that is needed in order for your BIOS to remember its settings, and also for your system clock to keep going even when your PC is not plugged in. (This is part of the BIOS settings).
