Hi everyone, not been a member here long but I am in desperate need of some help and/or direction I own a DC 2.0 Power Mac G5 and it had a 6600 128mb graphics card which subsequently died the other day. I have gone ahead and bought a Dell 7800 GTX 512mb graphics card with the intention of flashing it. I have no problem with the flashing procedure itself, I am having trouble locating a ROM for it. At first I thought I could flash the Quadro FX 4500 2149 retail ROM but later found out that the Quadro FX 4500 ROM needs HEX editing which I cant locate a guide for the procedure. Ideally, if at all possible I would like somebody to provide me with the ROM file but in the meantime I am trying to make headway myself. I've contacted japamac through his website to see if he could provide me with the ROM and am still awaiting a response. I realise the guy is busy so i'm trying to do the work myself. Does anyone have a link to a guide to hex edit the Quadro FX 4500 ROM to work on the 7800 GTX 512mb. Any help is massively appreciated guys. Thanks for looking. EDIT: This issue has been resolved thanks to japamac, he contacted me.
