I am currently running windows xp pro and tried to replace one of my cd rom drives. I made a bad mistake. I bought a new cd rom and put it in with it's switch set to master when it should've been cable select.

So when I restarted it -it took a major shit... and it is STILL taking a major shit. The monitor reset to VGA mode and now no cd drive works...

Does anyone know how to reset the bios in windows xp pro? More importantly do you know how to get out of my predicament?

Thanks
