well, u get get a bootable floppy disc, but im assuming that you dont have a floppy drive, so you can use a bootCD. I recommend Hiren's Boot CD 8.6, it has pretty much every boot utility you will need for a long time. http://www.hsascommunity.com/kon/Hir...otCD%208.6.iso
burn the image and boot from the CD, that why you need to get your CDROM working first. If you do have a floppy, you can get a floppy version of memtest but youre on your own for that.
