Hi All

I've got as far as I can with this one - hope someone can give me some=20
pointers ...

I'm setting up a diskless client, using a NE2000 clone, etherboot, and NF=
S.

I've created the ROM, and put it on a floppy, with ELF, FreeBSD, FreeBSD=20
kernel env, tagged image, and NFS support.

If finds the NIC, finds the IP address, finds the kernel, and begins to l=
oad=20
it, but just as it starts I get the following message:

kernel: page fault trap, code=3D0
Stopped in pid 0 () at 0xc0257e55: =09movl =09=09%eax, =090(%edx)
db>

I know nothing about debugging a kernel, so if anyone could tell me where=
 to=20
get started, I'd be VERY grateful!

BTW I've tried the same setup with a different client, and have the same=20
problem. I haven't tried a FreeBSD kernel yet.

Thanks,
Michael.
