Run All Above Checks
To run all the tests on the menu in sequence, press 10 and Enter.
When you choose this option, all video checks are performed
automatically, in sequential order. Although you do not start each
test, you must still supply the appropriate responses to progress from
one test to the next.
Floppy Disk Drive and Controller Check
Use this option to test the performance of your diskette drive. This
test sequence includes several checks that allow you to identify
particular problems related to your diskette drive.
To run these tests, you need a formatted 1.44MB or 720KB diskette
so the tests can write data on the diskette in the drive. If you are
testing an external 5 1/4- inch diskette drive, you also need a
formatted 5 1/4-inch diskette for that drive.
Start the tests by selecting option 6 from the DEVICE LIST menu.
After you choose the number of times to run the tests, the screen
displays this menu:
