2-3. How to Start the Diagnostics
Precaution: The supplied floppy disk containing the diagnostics program can be damaged because it will be written the Log and used as FDD read-write test. Be sure to make a backup of the diagnostics floppy disk and use a backup disk for diagnostics.

Starting up the diagnostics

Turn off the main power of the system once and back on to boot up the system from the diagnostics FD. When the system is booted from the diagnostics floppy disk, the start menu appears.
