I made with MS-DOS, then "FLASH895 ma79xds5.f6" command. PASS all, power off then: CHEKSUM ERROR BIOS RECOVERING... and return the factory BIOS: F3... f**ked Gigabyte DUALBIOS! ASUS A8N-E with rev.1013 BIOS working great on vista 32/64... Why bought this new mobo for my son. Maybe the 4 GB RAM cause this problem?
