I have a CC with a LC 575 Board installed, have been using the ResEdit hack with system 7.5. Downloaded the 19 part 7.5.3, installed but the resedit hack does not seem to work. Even after performing the resedit hack, I still get the bombs on boot. I have tried to boot with extensions off but it still bombs. Boots fine with the original CC motherboard. Does the resedit hack not work after 7.5 or does anyone have any suggestions.
