Adding an 80287 Coprocessor
Use the
Coprocessor
option if you add an Intel ® 80287
numeric coprocessor to your system. If you later remove the
coprocessor, use this option to delete it from the list of
equipment that the computer maintains; this prevents software
from trying to use the 80287 commands.
Follow these steps:
1. Highlight
Coprocessor
and press Enter. You see this
menu:
80287 not installed
*** SAVE SETTINGS ***
2. The 80287 not installed line is highlighted.
Press Enter to change the setting. This line alternates
between
80287 not installed
and 80287
installed
each time you press Enter. Highlight the
correct setting.
