The verifying DMI is not a corrupt BIOS. You get it when you change a disk. I've just had it and it's a pain to get rid off. There seems to be very little on the net about it, but it is NOT a corrupt BIOS. I got rid of mine (upgrade from 250GB to 1.5TB) disk by unplugging the disks, booting off a flash drive and then pluggin and installing. YMMV.
