Re: graphic corruption ?
if u have an AWARD bios u can get winflash for it and that doesnt need to be booted in dos to flash the bios, ive used it a lot and so far no probs. If u dont want to do this, and i also dont have a floppy drive, i use a collection of tools call hirens boot cd.
it writes amongst loads of other nifty tools, a dos program, several in fact to the cd/dvd and u can flash ur bios from one of these. Just boot off the disk and go into dos, easy as that.
And yes u get ur bios off the mobo site.
