If you have added a hard disk drive and you want to load
MS-DOS or another operating system from that drive, you need
to install the operating system on it. See your MS-DOS
Installation Guide or the documentation that came with your
operating system for instructions.
If you install an optional memory card, use the setup program
that comes with it to configure the computer for use with the
card. See your memory card manual for instructions.
Additionally, you may need to add some commands in your
configuration files. See your MS-DOS Reference Manual and
the manual that comes with your optional equipment for
instruct ions.
You may also want to test a newly-installed option. Some
options come with their own diagnostics test programs, and you
can use the diagnostics programs on your Reference diskette to
test the following:
System memory
Serial and parallel ports
Disk drives
Monitors and display adapters.
See Appendix C for instructions.
