Hello I´m new to the forums but i´ve found a lot encouraging info here and hope that you might be able to help me with my problem. A few day ago i flashed my Sapphire ATI Radeon X1800 XL with the Sapphire ATI Radeon X1800 XT Bios from the Bios download section of www.techpowerup.com. The 1st flash went all right, booted to windows, reinstalled ati catalyst 6.8...all was fine except some image corruption in 3D Mode. So i used the RaBit v2.1 Bios Editor to further increase the GPU Voltage, flashed again...all ok, more garble on the screen in 3D (2D picture is fine). Modiefied the Bios about 3 or 4 times...no problems flashing the card. Then i tried to reflash the original bios previously saved to my HD with atiflash...than the shit happens...atiflash exited with an error "No Adapter Found". Obviously that last flash went bad and after i checked what could be the reason for that i found that my DOS Bootdiskette was corrupted and my graphics card´s bios too. I tried nearly everything...atiflash -f -p 0 mybios.bin -> "No Adapter found", flashrom -f p 0 mybios.bin -> "No Adapter found", ATI winflash -> "No valid ATI Graphics card found". Finally i came to try uniflash which had no support for ati graphics cards or the bios chip. So i modified the available uniflash sources (st.pas) and added accordingly to the addchip.faq file the STMicroelectronics M25P05-A chip to st.pas which seems to be the one on the card. Compiled it, ran it with parameters uniflash -pcirom 2 0 0 -e mybios.bin -force 2005 (2005 is the id for the st M25p05-a chip). Chip detection was successful, but it did not flash because there is a disk error (Error #100: Disk Read Error) The card id is stuck at device ID 7000h which is no valid ati card id -> no go on installing windows drivers...(i even tried to hack the drivers .inf files to add support for the 7000h id but on installation of the last file in the driver´s file set the pc crashes)... PLZ HELP ME!!
