Type of Test Description
Tests the system video graphics
test screen
hardware and monitor.
Tests the floppy drive response
test floppy
to commands.
Tests the SCSI interface logic on
test scsi
the system board.
Performs a self-test diagnostic
test cdrom
on the CD-ROM drive.
Performs an internal and an
test net-aui
external loopback test on the
AUI (Thick) Ethernet interface.
Performs an internal and an
test net-tpe
external loopback test on the
twisted-pair Ethernet (TPE)
interface.
Performs an internal and an
test net
external loopback test on the
auto-selected system Ethernet
interface.

Preparation
The diag-switch?
NVRAM parameter must be
set to true.
Insert a formatted diskette
into the drive.
The diag-switch?
NVRAM parameter must be
set to true.
The CD-ROM must be set to
SCSI target 6 and have a CD
inserted in the drive or the
test will fail.
A cable must be connected
to the system AUI Ethernet
port and to an Ethernet tap
or the test will fail the
external loopback phase.
A cable must be connected
to the system TPE port and
to a TPE hub or the test will
fail the external loopback
phase. If the tpe-link-
test? parameter is false
(disabled), the external
loopback test will appear to
pass even if a cable is not
connected.
A cable must be attached to
the system and to an
Ethernet tap or hub or the
external loopback test will
fail.
