Greetings --

I'm new to NetBSD, (my experience with Un*x(s) is limited to SGIs and
DECs [should I now say Compaq(s)?])

When booting my Mac SE/30, I get a Kernel FPU trap.

The SE/30 has 20 Megs of Ram, a Quantum harddrive.

I created the A/UX root & usr partition along with a swap partition as
well.

I created the file system using the MacOS tool, and also used the
Installer to install all the packages in mac86k 2.3 directory:

base23.tar.gz, bsd-generic.tar.gz, comp23.tar.gz, etc23.tar.gz,
game23.tar.gz, man23.tar.gz, misc23.tar.gz, text23.tar.gz, xbase23.tar.gz,
xfont23.tar.gz, and xserv23.tar.gz.

I selected Build devices so that all my dev/* files would be created... 

I have mode 32 installed, and I have diabled every other extension and
control panel I could find. (at startup the only one which is presented is
mode32).

Specifically the Kernel FPU trap is:

Oops! -- I just got a different error:

panic: trap: type  0xf, code 0x0, v 0x0 -- no pcb

Ok -- now it is a Kernel: MMU fault trap

using OpenBSD 2.3 (GENERIC) #3: Wed Apr 22 07:12:55 MDT 1998
  root@hoffman.ucs.ualberta.ca:/usr/src/sys/arch/mac68k/compile/GENERIC

mrg:'Mac II class ROMs' ROM glue, tracing off, debug off, silent traps
mrg: I/O map kludge for ROMs that use hardware addresses directly.
vm_fault(1a2000,4e560000,3,0) -> 1
   type 8, code [mmu,,ssw]: 4010715
trap type 8, code = 4010715, v= 4e560000

Thanks,
