Hi, I need help with a Powerbook Pismo. It will not boot past the screen lighting up with a hard drive plugged in. Any hard drive! Once I unplug the hard drive it boots to the flashing question mark icon. Again, with a hard drive plugged in it won't go pass the lit up screen, nothing else, no icons, no beeps etc.
What I have tried:
reset nvram and all in open firmware, nothing
reset button on back, nothing
new hard drive cable, nothing
many different hard drives, nothing
zapping the pram, nothing
I can boot from a CD but the hard drive has to be unplugged. If it is plugged in than it won't boot from a cd, with C held or not.
