YEP, bios from PowerColor 4770PCS also do not work. That is bad, very bad.
I have both cards and I must say red one is very good overclocker, from blue I cant say that.
Maybe, if you OC only GPU, it must go till 960MHZ without voltmod.
If anyone flash card with PCS 4770 bios, you can wake up the card again in DOS and you must have two graphic cards. The working one in primary PCI-E and the "death" one in secondary PCI-E slot.
This is a manual for flashing in DOS(it works for me)
<1>. Commands
If you only have ONE card, then use this command-
atiflash -p 0 biosname.rom
If you have a crossfire setup, the use this command-
atiflash -pa biosname.rom
(This will flash ALL video cards)
-i [NUM]Display information of ATI adapters in the system
-ai [NUM]Display advanced information of ATI adapters [NUM] if specified
-p <NUM> <FILE> Write BIOS to image <FILE> to all approriate adapters
-s <NUM> <FILE> [SIZE] Save BIOS image from adapter <NUM> to file <FILE>
First [SIZE] kbytes (except for Theater in bytes) of ROM
-cf <FILE> [SIZE] [SUM] calculate 16-bit checksum for file <FILE>
Checksum for the first [SIZE] kbytes of the file is calculated if [SIZE] is specified
-cb <NUM> [SIZE] [SUM] Calculate 16-bit BIOS image checksum for adapter <NUM>
Checksum for the first [SIZE] kbytes of the ROM content is calculated if [SIZE] is specified.
-t <NUM> Test ROM access of adapter <NUM>
-v <NUM> <FILE> Compare ROM content of adapter <NUM> to <FILE>
-f Force flashing regardless of security checking BIOS file info check OR boot-up card
-fa Force flashing bypassing already-programmed check
-fm Forec flashing bypassing BIOS memory config check
-fs Force flashing bypassing BIOS SSID check
-fp Force flashing bypassing BIOS P/N check
-pcionly Enumerate only PCI adapters
-agp Enumerate only AGP adapters
-pcie Enumerate only PCIE adapter
-reboot Forec a reboot of the system after successfully completing the specified operation
So you need to enter this command in dos:
atiflash -p 1 biosname.rom
Where is no. 1 this mean device nomber. If you want to flash card in primary PCI-E slot, than there is no.0 else is no. 1.
