I have a PowerMac G5 and it refuses to boot into Open Firmware. I used Command + Option + O + F and held down the Option key. I have tried 3 different Keyboards but no avail.


PowerMac, Mac OS X (10.4.11)

Hmmm, does it boot in either of these modes?

Hmmm,

 

Does it boot to Single User Mode, CMD+s keys at bootup, if so try...

 

/sbin/fsck -fy

 

Repeat until it shows no errors fixed.

 

(Space between fsck AND -fy important).

 

Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Does it boot from your Install Disc, or show boot choices  when holding alt at bootup?
