Troubleshooting Flowchart
Use the flowchart in Figure 2-1 as a guide to determine which FRU troubleshooting procedures to
execute. Before performing the flowchart steps, verify the following:
❑
Verify with the customer that Toshiba MS-DOS is loaded on the computer. Other
non-Toshiba operating systems will cause the computer to malfunction.
❑
Make sure all optional equipment is disconnected from the computer.
❑
Make sure the floppy disk drive is empty.
NOTE: If you forget the password and cannot start up the computer, connect the printer port
wraparound board (F31PRT), then turn the POWER switch on. The computer will override
the password function by erasing the current password.
