Both behaved the same way. Got to the installer menu, I choose an install mode,
showed "loading..." for approximately 1 minute bit, then showed normal messages like
'Quiescing OpenFirmware...' and 'Booting Linux via __start()', and within 1 second Linux printed:
but after that nothing more. After 1-2 minutes the fans spun up fully. After 3-5 minute I gave up and held power button to power down.
This one got to the four smp_core99_* messages, but the fans did not spin up. I waited 12 minutes but the screen did not update.
Is there anything I can help to diagnose from my end?
