Adding an 80287 Coprocessor
Use the Coprocessor option when you add an Intel 80287 numeric
coprocessor to your system. You can run software on your computer that
makes use of the 80287 coprocessor. The 80287 works together with the
80286, which is the main processor, to process mathematical computations
very quickly.
When you install an 80287, use this option to notify the computer so it
will use the coprocessor. If you remove the 80287, use this option to delete
the coprocessor from the equipment list; this prevents software from trying
to use the 80287 commands.
Follow these steps:
1. On the main menu, press to move the cursor to Coprocessor and
press Enter. You see this menu:
*** SAVE SETTINGS ***
2. Press Enter to display the correct setting. The display changes from
80287 not installed to 80287 installed each time you press Enter.
3. Display the correct setting, save it, and return to the main menu to
change other settings.
