Hello guys.
I registered to say thank you :-) This finally worked!
I was stupid enough to flash to 1404 bios (don't fix what works, right?), and it borked my system.
I finally managed to create an USB boot drive (as I don't have a floppy drive) and started up the 1.06 AWD flash tool. And to my irritation it said Unknown Flashtype on both 1103 and 1205 bios.
So I tried with the newest AWD flash tool, 1.31. It accepted the bios 1205, but complained that it was an older version and that I couldn't flash.
Then I tried the command "awdflash.exe /f 1205.bin" and it started flashing after creating a backup of the 1404 bios. You can imagine my relief :-D
For those of you who doesn't have a floppy drive and want to boot from a usb drive, check out this page which explains the process to great detail: http://www.gamebeat.net/forum/showthread.php?t=1057
Thanks again guys!!
