Grey Screen - Won't start up in OS9
Here is what I've tried :
- Zapping PRAM
- Restting the PMU (the computer worked for a day afterwards)
- Replaced the PRAM battery
- Tried holding down the "shift" key when starting up, the screen stayed grey and didn't progress.
The computer WILL start up in OS 10.3.9 when I hold option down and select the start up disk, and it seems to works fine. It will restart into OSX, and remain in OSX, without incident, as long as it's selected as the startup dick.
The computer will NOT boot up using the OS9 CD. When I restart (from OS X) and hold the "c" key I get a grey screen. When I hold down the "option" key, while restarting, I have the option to choose the CD, but it gives me the grey screen after hitting the arrow.
It will boot up using the Hardware test CD, it passed all of the tests (including the extended)
One time today, it got to he point of loading the OS9 extensions and stalled. About a minute or so later the cursor tuned into a little "bomb". After that one time the screen went back to being grey each time I tried starting up.
Does anyone have any advice? I figure that since I can use OSX I should be able to do something.
