Thanks to Paul Kranenburg, the bug preventing the 4/110 from booting
from SCSI, (or even using SCSI as root) has been squashed!  The fix
has been committed, and those using SUP should have it already. 
Here is the patch I got from Paul, for those interested:

diff -c -r1.27 vm_machdep.c
*** vm_machdep.c        1996/05/16 15:57:31     1.27
--- vm_machdep.c        1996/08/01 19:49:29

         */
  
        write_user_windows();
+       opcb->pcb_psr = getpsr();
        bcopy((caddr_t)opcb, (caddr_t)npcb, sizeof(struct pcb));
        if (p1->p_md.md_fpstate) {
                if (p1 == fpproc)


If any 4/110 users out there need a new GENERIC kernel, let me know.

Thanks again to Paul for finding this one!
