4. Check that the Unused item equals 0 (zero). If not repeat steps 2 and 3
as necessary.
Note: Do not exit the Setup Program with the Unused item showing any value except 0.
Allocate memory to the other memory item until Unused equals 0; otherwise, the
computer will report an error condition the next time you try to start it.
When you start (boot or reboot) the TravelMate 3000, the Setup Program checks the total
memory available. If your settings exceed total available memory, the computer displays
an error message the next time it boots, asking you to run the "SET_UP" program. Press
the F1 key, follow the prompts, and check your memory settings.
