woohoo!! i tried it again with new atiflash software from
http://www.techpowerup.com and a little help of command line from techpowerup.com forum, and it works! i get my vga card back to normal again.
thank you very much prozac26 & wuzy!! i really appreciate it!! woohooooooooooooo
to wuzy: it's me enorhc at your ym list hehe nice to have you back here again though not so often.
for all the people who experience the same like me could do the trick with atiflash, another pci vga card or another card if you can go with dual agp/pcie card, floppy disk, your default bios rom/bin, and the command line:
atiflash -p 0 -f -newbios thebiosfilenamehere
(e.g: atiflash -p 0 -f -newbios r580.rom)
good luck.. as i've been trying straight 6 hours to get my card back to normal and i finally did it after being helped here and there through forums like this. you guys are awesome!
