I have tried to update the BIOS in my Crosshair. I tried the USB Flash drive first, but the BIOS doesn't find it.
I then tried the Floppy disk way but the message I get when I choose the file is:
"The Program Files Part Number Does Not Match With Your System".
I then tried EZ-2 bios update from the BIOS. The message then reads:
"The File Size Does Not Match Existing Bios Size".
I didn't know that one bios file must equal the old one in size. Sounds weird!
If you haven't seen the warnings yet, let me start out by saying do NOT use any Windows based BIOS update utilities. The safest way to do it is from within a BIOS or boot utility and differs somewhat per motherboard manufacturer. Sounds like you're going down the right path already by using EZ Flash 2 from within BIOS.
I have SUCCEEDED!
There are 2 1304 BIOS files. Versions 1 and 2.
I used 2, as it indicated it was the same size as 1.
But, when I extracted the files to a floppy, version 2 is 512kb and version 1 is 1024kb.
I checked my 1207 BIOS size and it is 1024kb. I guess that was my problem all along.
Sorry for getting all het up about it.
Lucky the motherboard didn't let you apply the wrong one. Always be careful to get the latest BIOS that matches your motherboard. I don't know how Asus versions (revisions?) their boards, and I didn't see 2 different BIOS files on their web site so I'm not sure what you were looking at, but it looks like the key was there in your recent post "ASUS Crosshair V1"
