second reply on that topic:
I booted the bootonly ISO of BETA-2 with boot-v
The system hangs hard, no NUM-Lock or SCROLL-Lock possible, and if I 
understood the manual right, CTRL+ALT+ESC should bring me to the debugger.
Doesn't work either :-/
looks like a hard-lock.

Any more ideas ?
I do have a BETA-1 Kernel around. I'll give it a shot, wether I can get 
into the debugger there... but I suppose it'll be the same.

This time the the boot procedure stopped with the following last few 
messages (hand transcribed):

(ahd0:A:0:0): Sending PPR bus_width 1, period 8, offset fe, ppr_options fb
(ahd0:A:0:0): Received PPR width 1, period 8, offset 7f, options c3
	Filtered to width 1, period 8, offset 7f, options c3
ahd0: target 0 using 16bit transfers
ahd0: target 0 synchronous with period = 0x8, offset = 0x7f (DT|IU|RTI)
(ahd0:A:1:0): Sending PPR bus_width 1, period 8, offset fe, ppr_options fb
(ahd0:A:1:0): Received PPR width 1, period 8, offset fe,options fb
	Filtered to width 1, period 8, offset 3f, options fb
ahd0: target 1 using 16bit transfers
ahd0: target 1 synchronous width period = 0x8, offset 0x3f(RDSTRM|DT|IU|RTI)


and that's it :-/

any more chances to get some debugging infos ?

best regards,
Marian
