I had a PC 8500 that I flashed, but it kept overheating so I tried to underclock it with Res Edit by some instructions from coffehaus, and I ruined it I guess. Of course I found the already done flashers right after I blew it heh. No Mac's will boot up with it in, and I've tried everything to flash it back in a PC and I just cant seem to do it, I guess since the processor/ram is done wrong in the firmware, It's just dead. Anyone have a last thought? Thanks.
