Ok ...
got a quicksilver 2002,
733Mhz, 768MB RAM
DIGI001 - pci card installed .

I can't boot from the MorphOS-CD .

Quark / Openfirmware console failed .
System : (PowerMac3,5) Rev <>
CPU0: <PPC7450> Version 0x0000 Revision 0x200
CPU0: CPUClock 733333331 BUSClock 133160004

THAT is all I get when I try to boot off the cd .

tried two brands of CD/DVD-drives .

dunno 'bout the Graphics-board .

Please,
help me out !!!

I think you should check out whether you have an ATI or NVidia gfx-board installed.

There is no QuickSilver2002 with 733MHz, what does exist is a 2001 model:

This one came with a GeForce2 as standard GFX-card (not supported).

I got a spare Radeon7000 and 9000pro (both Mac-editions) but depending on your location it might be more sensible to look out for one on ebay or suchlike.

ok ... got myself a box of display adapters from my neighbor ; (:

problem is they're all pc versions ;

how can I make them mac compatible, how do I flash the rom ?

for all I've gots this PowerMac G4 and a Intel Macbook .
