I'm in the process of installing mach on a Sun 3/60 with 2 71 meg hard
drives strung off of it.

So far, I have set up the hard drive partitions properly with respect to
the way Mach expects them.  I have loaded the root, sys0, and usr0
partitions.  All of this was done while the Sun was operating as a diskless
client.  I even ran the installboot program as the instructions said.
I rebooted the machine and got the following error while it was trying to
load the kernel:

    Invalid Page Bus Error
	Vaddr: 0E08CD90, Paddr: 00000D90, Type 9, Write, FC 5,
	Size 4 @ 0x0E00407C

The only possible reason I could think of involves the file systems.  I ran
the Sun newfs, using the Mach distribtion mkfs, to create the filesystems
for the proper partitions.  I then mounted these partitions on the diskless
client and then restored the root and untarred /sys0 and /usr0 onto the
proper partitions.  I then ran the installboot program to make sure the
boot blocks were properly set up on the hard drive.

Is there a problem with the way I restored everything?  Could there be an
incompatibility problem with Mach filesystems and SunOS 4.2 filesystems?
I was told there shouldn't be.

I'm kinda dangling at the end of my rope on this one.  Anybody out there
have any suggestions or solutions?

Thanks,
