hey hey everyone, the bios chip in my older computer is completely gone, over-written somehow. When I start it up nothing happens excepts for the power coming on. This is an IBM Aptiva. I called IBM up and ask if i could just buy another bios chip, however I can't, I have to buy the whole motherboard which is over $400. So, i was wondering, if I could replace it with another bios chip or am I going to have to replace that motherboard?
