Flashing BIOS - Page 2

post #11 of 13
Pulling the battery is basically clearing CMOS^2. It's IMPERATIVE you get the cmos fully clear in a BIOS flash on the NF4s. I can personally attest to that. I did the 'normal' CMOS clear of about 10 seconds and flashed my SLI-DR BIOS and the SOB wouldn't boot anymore and I thought I borked my flash. It took about a 3-5 minute BIOS clear to get it done right and allow my board to boot. For whatever reason there is a lot of time needed for the DFI NF4's to clear fully.

So the guy at DIY-Street is really just being ultra cautious.

True...except on the Nf4 expert boards. There are also cases where 24 hour clears are required.

ahhhh, i see. Tmod said the NF4 boards takes about 10mins with the battery removed and the expert takes really really long because you are not supposed to remove the battery.
