Select option 5 from the menu to start this test. First the program checks

the selected drive type; if the drive is a 360KB drive, you see these messages:

Drive 

is a 360KB drive.

DISK CHANGE is not allowed with this type of drive.

Press ENTER to return to the menu.

d represents the name of the drive you selected.

When you run the test for a 1.2MB or 720KB 

drive, you see this

prompt:

Remove the disk from drive 

Release the disk drive lock, and remove the disk. You see:

Re-insert the disk into drive 

Re-insert the diskette and secure the lock. If no errors occur, then the menu

reappears. An error occurs if the drive is malfunctioning, or if you do not

remove or replace the diskette within a certain time.

To run all the tests on the menu in sequence, press 6 and then 

When you choose this option, all checks for the floppy disk drive(s) and

controller are performed automatically in sequential order. Although you do
not start each test, you must still supply the appropriate responses to progress
from one test to the next.

Use this option to check the operation of the 80287 math coprocessor if

you have one installed in your computer. To check the math coprocessor,
select option 7 from the DEVICE LIST.

Before running any tests, the computer checks the settings in CMOS

RAM to ensure that a coprocessor is installed. If the coprocessor is missing,
or if you have not changed the setting in CMOS RAM with the Setup
option, an error occurs and the test ends.

If the coprocessor is installed, the program then runs a series of checks

on the precision with which the coprocessor performs calculations and han-

dles exceptions.
