"Adapter Not Found" When Running AtiFlash.exe

[omgcoins]

Hi Everybody,

Do you all know or experiencing with "Adapter Not Found" issues when run AtiFlash.exe -i from CMD?
I tried AtiFlash.exe -i 1 still won't show up. My system (6 PowerColor RX580 ) is mining at 22-24 mh/s just fine and i want to mod it but ran into issues when initially run atiflash.exe. Cards are brand new and never bios flash before.
Any solution for this would greatly appreciated.
