If BIOS is reset on a pc, will an already installed XP & already installed Drivers be reset too? My HDD is a SATA and for it I had to install a Driver from a floppy, will the driver be removed if I reset BIOS?
Resetting the bios has nothing to do with what's on the hard drive. Nothing will happen with XP, drivers, or anything of the sort. This ONLY changes what can be configured in the bios(overclock settings, higher-level motherboard settings, etc etc) Sometimes it'll reset your time, and perhaps other things like that. You may lose your drive configuration, but this is typically set automatically by the bios.
My problem is that I want to add a IDE HDD set as a Slave that I used on my last pc. It has a lot good files on it that I don't wanna lose. But when I hook it up I get a NTLDR Is Missing, and the pc wont load into XP. Someone suggested to reset BIOS to fix this problem.
