If you still have trouble with your hard disk, you can back up your data and physically reformat the disk. Then you’ll need to reinstall MS-DOS and copy your files back onto the disk.

See “Hard Disk Format” in Appendix C and your MS-DOS Reference Manual for instructions.

If you cannot access data on your hard disk or you are receiving read/write errors, the disk may have a physical problem. Contact your dealer.

Software Problems

If you are having trouble with an application program, try the following solutions:

1.If the application program does not start, check that you are following the correct procedure for starting the program, and that it is installed correctly. If you have a hard disk and the program is stored in a directory on that drive, make sure you are logged onto or specifying the correct directory. If you don’t have a hard disk, make sure you have inserted the correct diskette in drive A.

2 . Your computer can run at either high speed (16 MHz) or low speed (8 MHz). While almost all programs work properly at the faster speed, some must run at the slower speed. Check your software manual to see if this is the case, and change the CPU operating speed if necessary. See “Changing the Processor Speed” in Chapter 4 for instructions and for information on accommodating copy-protected programs.

3.If you have entered an MS-DOS command that you want to stop, there are special key combinations you can type to tell MS-DOS to stop what it is doing. These methods may also work in your application programs:

0 Hold down Ctrl and press C

CI Hold down Ctrl and press Break.
