Method 2, using the AFLASH (v221) from Asus website as recommended. This "worked" in terms of loading (successful flash), but upon re-booting the PC made nasty beep sounds. Reading the manual for the mobo, I discovered that I needed to put in an extra PCI video card to see any possible error messages. I added a card, and sure enough "BIOS checksum error" was reported on the new flashed bios. Thanks to ASUS crash-free BIOS, I was able to then re-load V1005 (which I had previously saved as recommended by the AFLASH utility.
OMG! I had exactly the same problem. I flashed with the 1006pmx bios from the site and the motherboard just started beeping. I had a AGP VGA around and plugged it in. "BIOS checksum error"... I nearly died
Seeing as I didn't have the MB CD I thought I was screwed but luckily I had a MSDOS boot floppy. I used a friend's computer to copy the good BIOS there and was able to repair it. I won't ever try that again!
That's what I get for trusting this website... the AFLASH did warn me that that BIOS wasn't right for my MB
