If you install a hard disk drive that has never received a hardware level format (such as some non-Epson hard disk drives), you need to format the disk. Check the manual that came with your drive, and then, if necessary, follow the instructions in Appendix B to format your new hard disk.
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 manuals 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 to your configuration files. See your MS-DOS manuals and the manual that comes with your optional equipment for instructions.
You may also want to test a newly-installed option. Some options come with their own diagnostics test programs, and you can use the diagnostic programs on your Reference diskette to test the following:
0 System memory
0Serial and parallel ports
0Disk drives
0Monitors and display adapters. See Appendix B for instructions.
