i tried and for some reason when i mod the original bios the card cannot detected by the driver and i get an error code 10 on Vista
i have flashed countless vga's but i can't understand what the fluck is happening on this one
and i have seen this only on sapphire 4850's both 512 and 1Gb versions
i tryied all your bios's for the 512 and it does the same think
