When you get to the last screen, you see this prompt:
Is the display correct (Y/N)?
If all the colors or shades are correct, press Y and Enter to end the test. If
any color is displayed incorrectly, first check the adjustment of your monitor,
and then make sure that both ends of the cable are plugged in firmly. If a
problem still exists, press
N
and
Enter
to display the error message.
Run all above checks
To run all the tests on the menu in sequence, press 9 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 Drives and Controller Check
Use this option to test the performance of the floppy disk (diskette) drives
installed in your computer. This test includes several checks that allow you
to identify particular problems related to your diskette drives.
To run these tests, you need a formatted 720KB diskette so the tests can
write data on the diskette in the drive.
