Problem Symptoms

Possible Causes/Solutions
Use the firmware
edt
command to see if the
equipped device table is
different from actual system
configuration. Remove all
cards from backplane and
reboot. If system boots, put the
cards back in one at a time to
determine which card is bad. If
no cards are present and
system still has trouble, replace
backplane or system board.
Use diagnostics on floppy to
see if the system board and
hard disk are functional. If so,
try to do a partial restore. If
that fails, replace hardware until
a partial restore is possible
(disk drive, system board,
backplane).
Try a new diskette. Try to
replace the floppy drive and
system board until diagnostics
on floppy or first core floppy will
boot. Hard disk is probably not
defective.
Check to see if the floppy is
write protected or was not
formatted properly. Format
with the
verify
command.
Run floppy diagnostics to test
the floppy drive.
