Flashing bios using 'easy-flash' method.
1. Enter bios and change clock speeds to default (dont forget to write down your stable overclock settings!). Believe me you don't want a corrupt bios flash due to an unstable overclock!
2. Download latest bios
3. Extract bios to desktop
4. Rename bios to A8N32SLI.ROM
5. Format a floppy. You dont need to create a dos disk just a simple format will do.
6. Copy A8N32SLI.ROM to the floppy.
7. Reboot
8. Upon 'post' press ALT+F2.
Once you press ALT+F2 an automated service will begin...do not touch anything until told to do so.
'please reboot PC' - Do as it says.
The first time you reboot you will get a 'bad bios checksum' notice. Dont worry! Press F2 to load setup defaults and then reboot again. Now you are back to a factory state (with updated bios). Load into windows to check you are stable and you have no problems, don't worry about missing peripherals (NIC, audio etc) as they will probably be disabled by default at this stage. Once you are happy re-rnter bios and load up your 'overclock' settings.
Hope this helps.
