No display signal after installing Debian on PowerMac 8600
I am a total newbie to Linux, so perhaps this is all stupid, but I have
a problem I cannot solve after installing the current build of Debian
on my PowerMac 8600.
Here it goes:
I (successfully) installed the basic installation of Debian (CD
distribution 1) for PowerMacs/PPC. I partitioned the hard drive,
installed some modules and then finished the installation. When it told
me that the installation was finished I restarted my Mac.
However, now I don't have a display signal! When booting of a split
second, the display receives a signal, but then goes blank. I can hear
the computer working and seemingly, it responds to keyboard inputs
(from the sounds it makes), but since the screen is black, I don't know
what's it's doing.
What's worse, I cannot boot in MacOS, either (neither booting from HD
nor CD). So I am completely stuck here.
Suggestions are truly appreciated.
Thanks in advance!
