You got a machine check. This may be due to broken hardware (unlikely),
bad memory (unlikely) or that the boot program addresses outside 
existing memory/hardware (likely). Fetch the

file and mopboot it. To avoid the earlier problems with mopbooting ( :-)
just put it in /tftpboot and call it something like

lrwxr-xr-x  1 root  wheel      8 Oct 30  2000 08002b09aacc.SYS@ -> boot.mop

and then just boot it: (change xqa0 to something more suitable)

>>>b xqa0
(BOOT/R5:0 XQA0)

This boot program at least boots my 4000/300 :-)
