Epson 10020 - Manual (Page 127)

Follow the instructions in Appendix E to perform a
low-level (Conditional) format.
Follow the instructions in Appendix F to prepare the
hard disk for use.
6. If you have installed a hard disk drive made by another
company in your computer, it may need to be partitioned
and formatted. If this is the case, see Appendix F for
instructions. If it needs a low-level (physical) format, do
that before you partition the disk. (See Appendix E for
instructions.)
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 (drive A).
2. Your computer can run at either 4.77 or 10 MHz. While
almost all programs work properly at the faster speed, some
must run slower. Check your software manual to see if your
application program must run at the slower speed, and
change the CPU operating speed if necessary. See Chapter
2 for instructions on changing the operating speed.
3. If you have entered an MS-DOS command that you want
to stop, there are special key combinations you can type to
signal MS-DOS to stop what it is doing. These methods
may also work in your application programs.
