Last working was June 10.  I think.  I'll try to figure out where 0x801e6a0c 
maps to later today.

Yes I will.  I had to change a couple things from MAGNUM to get it to work 
with my machine so I created a machine type, but in retrospect I'm not sure 
if it needed a machine type since the majority was the same as MAGNUM.  The 
only thing I can remember being different was
  COM_FREQ vs. COM_FREQ_MAGNUM.  For the M700 COM_FREQ works better.

In addititon to that I had to change the following.

  SCSI controller chip detection.  asc.c and ascreg.h  See previous post.
  The call to Arc_Bios_Save causes the machine to trap so I commented it out.

I also noticed that there's a reference to cpuregs.h in arc/include/Makefile 
which is no longer needed because we use mips/include/cpuregs.h.

I will be sending you my patches.

Thank you very much.
