I don't how to use EZFlash to update the BIOS. In the manual it says press <alt>+<F2> during POST. I don't what they mean during POST. During intial start-up i get the P4P800 Logo screen and if i press <alt>+<F2> there my monitor screen goes black and the monitor light turn to red from green. I don't why that happens. Anyone with any info, please help me. My BIOS version is v1005

Oh k.

but in the ASUS P4P800 deluxe unser manual booklet it shows 2 ways to update the BIOS. First through MS-DOS using the afudos which i tried but got errors and the 2nd is using the EZ-Flash utility which i don't how to.

What flash utility is it, i looked over the ASUS downloads page but couldn't find anything. thanks for the help.
