Drivers for hardware

[dman]

Ok, this might seem like a dumb question but I have to ask it(and yes...I'm a newby). On a computer you have drivers installed for video card, sound card, ect. Isn't it the same for the xbox? If I replace the hard drive and install new bios for a mod chip, is it possible that the video card won't be at it's peek performance due to drivers that no longer exist in the system?


Thanks,
