Test Descriptions

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.
SCSI Disk Read Test
This test reads logical blocks from the SCSI disk. If the starting logical block number and end logical block
number fields are not specified, the test starts reading from block 0 and terminates at the last block of the
disk.
SCSI Tape Unit Tests
SCSI Tape Buffer Test
This test writes data, reads back and compares with the data written to the internal buffer on the SCSI Tape
Unit.
The media is not accessed so data remains unaffected.
SCSI Tape Self Test
This will send Self Diagnose command to SCSI Hard Tape.
SCSI Tape Rewind Test
This command rewinds the SCSI tape using the SCSI rewind command.
SCSI CDROM Tests
SCSI CDROM Buffer Test
This test writes data, reads back and compares with the data written to the internal buffer on the SCSI
CDROM.
SCSI CDROM Self Test
This will send Self Diagnose command to SCSI CDROM. A CD platter must be present for this test to
work.
