Actually that won't help ... arcbios.c and arc port itself use very little
information from arc firmware,basically a comparison is done
on "system id" and if match is found the "arctype" is set...
All the rest of arc infomation is ignored... The arcdiag
output is used by developers to add a new "arctype"
 to various "switch statements" scattered though out the arc source
tree to handle things differently for various hardware designs.
...Bit ugly/hachish is the arc port...

Now I have two suggestions ..
1) Unplug all scsi trays/hard drives leave only original
CDROM attached...
    a)Select "manage setup" , select initailize system
       select option 'set default configuration' (set to default),
       select option "set default environment variables' (use CD-ROM as system
partition),
      select option  "environment variables" (check everythine normal),
      select option onboard SCSI termination (enable scsi port 1)
      Basically reset machine to factory defaults.
    b)exit out "manage setup" to main menu
    c)stick in the cd with the arc.iso burned to it.
    c)select option 'run a program' enter => cdrom:\install
          If you have a recognized risc r2200 it better boot !

2)I am making a new install called install.noscsi ...
you'll find it in the directory
ftp://204.57.142.148/NetBSD-1.5/
   Place that file to bootable medium (be sure to use 8.3 filenames
and is09660 NOT joliet format when burning to 'FAT' cdrom).
Try running that image (it will rule out scsi driver as fault)
