Here's a 0+2 mod you can try. Motherboard: Gigabyte GA-EP31-DS3L Bios Revision: F4 Bios Type: Award SLP1: Asus, Hewlett SLIC: Asus Edit: Link removed. Didn't work.
Since you're already running the same version 0704 don't worry about it. The main thing is to flash from DOS (afudos.exe) not Windows, no switches required. This is SSV3 which works for almost all Asus.
Exactly, Since you are already running the 0704 (without any mods), just flash the mod bios from DOS with no switches. Report back please.
Thanks Zort and P4spooky for the clarification. I've flashed bioses several times before without issue, though only because i followed instructions precisely and asked questions when not sure. Appreciate your input. Will be more than happy to post results, may be a few days.
