Title: unbrick broken 5770 (2xdvi/hdmi/dp) MacPro 1.1/2.1
Post by: kapqa on December 15, 2018, 05:26:27 PM
Hello ,


i am kindly asking your help as i yesterday tried first time flashing graphics card on mac pro and miserably failed.

proceeded the following way:


MacPro1.1 > in Bootcamp in Downloaded "GPU-Z" and saved current ROM from card 5770 ("Juniper.rom") > from Macrumors trusted member i "found" .Rom which supposedly function for this port mapping with 2xDVI/HDMI/DP - downloaded .rom ("5770e2.rom or similar) > in Bootcamp i downloaded WIN ATIFLASH > loaded .ROM and flashed


after reboot the card is no longer seen by macpro, neither in bootcamp nor in osx.
it could be that the .ROM i was using was meant for 64-BIT MacPro? or why else it could fail?


How could i now reflash the card with only having the MacPro 1.1/2.1 and no proper PC with integrated graphics or with 2 fullsize PciE Lanes Available?


Thank you very much for your help and input.
