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
application program diskette in the top drive (usually
drive A).
2. Your computer can run at either high speed (25 MHz) or
low speed (simulated 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 processor speed if necessary. See
“Changing the Processor Speed” in Chapter 4 for
instructions and for information on accommodating copy-
protected programs.
