The computer checks the color or monochrome display card

that is installed in the system. An error number and message

appear if any faults are found in the display adapter card.

Number 401 represents an error in the monochrome display

card, and 501 represents an error in the color display card. The

messages are:

401-CRT 

error

501-CRT error

If any additional memory (expansion RAM) is installed, the

computer then checks that RAM for any malfunction.

The computer checks its diskette drives by searching the

read/write heads for any malfunction.

If any seek errors are found, you see this message:

601-Diskette error

If this message appears, run the System diagnostics (described

in Appendix C) and select the Floppy disk drives and

controller test, option 6, from the DEVICE LIST. If the error

persists, consult your Customer Care Center about having the

drive repaired.
