What is the make and model or motherboard. If you want magic or mindreading your in the wrong forum.
Why not boot from a cd? I move them around all the time. A replacement bootable cdrom is less than 30.00.
Does your computer have sata drives? Atapi cdrom don't require drivers. I have long ago thrown out all cdroms that need drivers. Ide hard drives don't need drivers either unless there is some drive overlay to alter the way the LBA is used by the bios.
autoexec.bat and config.sys are not even read in xp unless you have some 16bit hardware or software that looks for it.
We can all sit here and make wild guesses, but if you really want to figure out how to do something, it is up to you to describe it and supply enough info to figure out what you are trying to do.
