I need to find out how to do this because I can't afford to purchase items to do this for me. My computer already has the audio sound card in it. It did when I got it, I had a tech. work on my puter to remove last persons info and he wiped the harddrive clean. He tells me that I can't use the audio card because we can't figure out the password.
I'm not even sure I understand the question. What does the BIOS have to do with installing an audio driver?
If you want to clear a BIOS password, you could look on Compaq's website for documentation - but that shouldn't have anything whatsoever to do with using a sound card.
