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 B and your MS-DOS
manuals 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 (20 MHz) or
low speed (10 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:
Hold down Ctrl and press C
Hold down Ctrl and press Break
