My Early 2008 Mac Pro won’t boot. Won’t do much, actually. This is what I’ve done:
- replaced the power supply
- removed DVD player
- removed all RAM
- removed all video cards (I have a handful of wonderful flavours)
- no drive at all (although I have a single HD with fresh test OS (I forget which OS though, but compatible as I’ve had it running on this box)
- replaced the CR032 battery with a tested battery having ~3V
BTW I’ve been referring to Mac Pro Service Source Manual but it has a different LED layout, so it’s extra confusing.
The box powers-up, with the fans spinning, front LED solid white. Nothing else. No chime. Tried pushing the
SYS_RST and nothing happens. I’ll include an actual pic of my LEDs when in this state.
Not sure what to do at this point. Any insight appreciated how I can make this do something. It is sitting in my garage which is ~6°C at the moment, so it’s not overheating at all half a second before startup. BTW I thought the similar white button TOP RIGHT of the motherboard was the SYS_RST, not the one in the image. I need some clarification on that.
