I have try more times and finally I flashed my HD7850 card ( at 1900x1200 resolution, before flashing ,my pc turned brick when starting a streming video).with the original bios ( taken from techpowerup.com) but after the reset of pc , blank screen.
I set this card at the 2nd pci x16 slot , I put an old nvidia card at 1st slot.
The pc was boot successfully. I tried to run the atiwinflash –unlock 1 or atiwinflash –f –p 1 xxx.rom ( version 4.0.7) , but I receive the message “ don’t exists any video adapter”
So, any help at this point please ?
Something else. Is better to try on the z77 asus mobo with G840 cpu which has on ot graphics processor ?
In this case , at which slot must put my brick card ? At the 1st one ?
Need to change something from bios ? ( this pc has video output either from the mobos dvi connector and either the vga card.
Using the atiwinflash ( 4.0.7 is ok? ) or atiflash must declare after the commands the 0 or 1 so to re-flash this card ( i.e atiflash –unlockrom 0 or 1)
Thanks for your help
