When you finish installing an option card and reconfiguring the system, you should test the option if possible. Some option cards come with their own diagnostics programs, and you can test others with the diagnostics programs on your Reference diskette. The options you can test with the Reference diskette include the following:

Expansion memory

8087-1 math coprocessor

Serial and parallel ports

Monitors and display adapters

Disk drives.

See Appendix D for instructions.

Optional Disk Drive Controllers

The built-in disk drive controller in your computer can control two 360KB (5 1/4”) or 720KB (3 1/2”) diskette drives. If you install an optional disk drive controller card in your computer to control the diskette drives, you must connect the drives to the option card, and disable the computer’s built-in controller by changing a jumper setting.
