Note

If your application program requires a monitor that supports graphics but you have a monochrome monitor, the results will be unpredictable.

7.If you installed a display adapter card (and did not connect it to the feature connector on the main system board), you must set jumper J10 to disable the built-in VGA adapter or you will not see anything on the screen. You may also need to change the setting of jumper J11. See “Changing the Jumper Settings” in Chapter 2 for instructions.

8.If you still have difficulty with your monitor, run the Video adapter diagnostic tests described in Chapter 4. If the diagnostics program indicates an error, contact the representative who sold you the monitor.

Diskette Problems

If you see an error message or have trouble accessing data on a diskette, try the following steps:

1.You may have inserted the diskette upside-down or it may not be inserted all the way. Remove the diskette from the drive and reinsert it. If the diskette drive has a latch, be sure to turn it down to secure the diskette in the drive. See Chapter 1 for detailed instructions on inserting and removing diskettes.

2.If reinserting the diskette does not solve the problem and you have access to another diskette drive of the same type, place the diskette in the other drive and repeat the operation. If you can read the diskette, the trouble may be in your diskette drive. See “Diskette Drive Problems” below.
