What kind of firmware does it have? Maybe OpenFirmWare?=20

The PReP spec is a bit vague, IMHO. It leaves some space for
implementation dependent bits, like interrupt handling.=20

So it does print all the lines about found devices?
What devices did it find?
It seams that it crashes when it tries to mount the root-fs. This is
quite a lot for an unknowen machine. The problem may be the interrupt
handling. The NetBSD kernel needs to know a few machine dependent bits
about your particular type of hardware. It shoud be easy to fix with a
bit kernel hacking and hardware documentation.=20

You need a kernel with console hardwired to com0. Try sysinst_com0.fs

This is not Linux. This is a NetBSD mailing list. Linux and NetBSD are
two independent and different operating systems. They both are free and
Unix-like, but thats all they have in common.=20
