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:

Cl System memory

0Serial and parallel ports

0Disk drives

0Monitors and display adapters. See Appendix C for instructions.
