Rita:
An RT in E52-364 -- E52-364-3 -- will not boot up from its disk. This
problem first appeared after I upgraded its memory to 8 mbytes. It would stick
on self-test 4c. These are the actions that I have taken:
Removed one 4 mbyte board to restore memory to 4 mbytes.
Powered on workstation -- it still hung on 4c.
Restored 4 mbyte board, bringing memory up to 8 mbytes.
Replaced HESDI board to check to see whether disk controller was
problem.
Powered on workstation -- it still hung on 4c.
Restored old HESDI board.
Ran diagnostics -- the machine wouldn't read the disks & now
hangs on 88.
Looking up hardware error 88 in the Problem Determination Guide
gives the Service Request Number 36-780.
Carlton may have an RT that can take the place of this machine.
The serial number for this machine is 26-0009861.
