Elevator seek Test
This test verifies the track-to-track seeking capability of the floppy drive. This
test is sometimes called a butterfly test.
Disk Change Line Test
This test verifies the change line capability of the floppy drive.
KBD (Keyboard) Tests
The KBD Test Menu includes testing the keyboard controller, scanning, LEDs,
clock line, and data line for proper functionality.
Controller Test
The controller test issues a Self Test command to the keyboard controller and
checks for an OK response. Then it sends the diagnostic echo command to the
keyboard and waits to get back the echo from the keyboard.
Keyboard LED Test
This test checks the functionality of the keyboard LED lights - Num Lock, Caps
Lock, and Scroll Lock.
Keyboard Clock Line Test
The Keyboard Clock Line Test verifies that the keyboard clock line is working
properly (it is not stuck at high or low).
Keyboard Data Line Test
The Keyboard Data Line Test verifies that the keyboard data line is working
properly (it is not stuck at high or low).Another
SCSI Device Tests
The SCSI Test Menu exercises all SCSI devices (disk drives, CD-ROM drives,
and tape drives) with buffer, self-test, and read tests; it also includes functions
unique to a particular device, including play, and rewind.
SCSI Disk Tests
SCSI Disk Buffer Test
This test writes data, reads back and compares with the data written to the
internal buffer on the SCSI Disk.
The media is not accessed so data remains
unaffected.
