"root on sd0a dumps on sd0b"

I've only installed the bare necessities (base, kern and etc) on the 
internal HD. There's a 25 Mb Mac partition (sd0e), 170 Mb Root & Usr 
partition (sd0a), and a 50 Mb swap partition (sd0b).

I've got 20 Mb ram in total, booting a trimmed down MacOS 7.5.3 with 
extensions off.

It boots and switches to full screen, lots of init stuff. :)
I get two errors, the dump, and one related to the floppy:

>iwm0 at obio: Apple GCR floppy disk controller
>iwm: Chip revision not supported (-77)

The last few lines read:

>fpu0 at mainbus0 (emulator)
>boot device: sd0
>root on sd0a dumps on sd0b

And then nothing.

The debugger still works. On entering it says:

>Panic switch: PC is 0x37c2
>Stopped at	_Debugger+0x6:	unlk	a6

Typing ps results in

>PID	PPID	PGRP	UID	S	FLAGS	COMMAND		WAIT
>0	-1	0	0	3	0x20204	swapper		scsipi_

Hmm, that's all I can think of which might help. Same addresses every 
time. Any suggestions?

Thanks in advance,
Thomas
