Post-installation Setup

After you install an option card (and replace the main unit’s cover and reconnect the power cord and peripherals), you may need to change your DIP switches to update the configuration information. For example, if you add a floppy disk drive, you need to change switches 1-7 and 1-8 so the computer knows it has the additional drive.

You may also need to add some commands in the configuration files on your system disk as well. See your MS-DOS manual for instructions.

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 diagnostic test programs, and you can test others with your diagnostics diskette. These tests include:

•Expansion memory

•8087 math coprocessor

•Serial and parallel ports

•Monitors and display adapters

•Disk drives.

See your Diagnostics manual for instructions.

Removing Option Cards

To remove an option card, first turn off the computer and unplug the power cord, then detach any cable connected to the card. Disconnect the monitor and keyboard, and remove the main unit cover. Then follow the option card installation instructions in reverse.

Follow the same safety instructions and make sure you pull the card straight up and out of the connector to avoid damaging it. Rewrap the card (preferably with the original packing materials) and place it inside the packing box for safe storage. Replace the metal access slot cover before you replace the computer’s cover. If the card you removed had an external connector you also need to replace the plastic access slot cover on the back of the computer. When you have reassembled the unit, remember to reset any DIP switches if necessary.
