1.6.1 PREP kernel panic on RS6000 43P-140

[Rongsheng Fang <rfang%cs.gmu.edu@localhost>]

Hi All,

I am trying to install NetBSD 1.6.1 prep port on my
IBM RS/6000 43p-140:

CPU: 604e 332Mhz
Mem: 384M
Type: 7043-140

But the 1.6.1 prep kernel always panics. I searched
the port-prep list, but didn't find any posts showing
the same problem.

Here is what I did:

1) I was using a serial null modem cable in the whole
process of installation.
2) I booted the machine with a floppy that had generic_com0.fs
image on it.

dmesg is attached as follows:

>> NetBSD/prep BOOT, Revision 1.5

Could anybody kindly tell me what's going on and how
to install NetBSD 1.6.1 prep port on my 43p-140?

I'm not subscribed to this list yet, could you please cc me a copy
when you reply?

Thanks very much,
