When I plug my Apple Studio Monitor into my G4 by way of the "ADC" port on my video card I cannot boot into my OS 9.22 volume, nor my OS 9 install CD. I get only a totally gray screen. I can boot into OSX 10.3.9 with no problems.
If I go into open firmware I see these error messages:
USB Setup Error: 5c000000 8200
USB Setup Error: 5c000000 8206
If I unplug my Apple monitor and plug a monitor into the VGA port on my video card all of my problems disappear. I can once again boot into OS 9. I get no error messages in open firmware.
Can anyone help me determine if my problem is with my video card (specifically the ADC port on the card since the VGA port works fine) or my Apple Studio Monitor.
I do not have access to another Apple Studio Monitor or another G4 with ADC connectors so that I could test things that way.
I have written about this problem to different forums over the past month usually under the title "OS 9 Gray Screen". I feel that I'm finally zeroing in on the problem and was hoping someone would have some ideas.
Thanks,
Philip
