Type of Test Description
Tests the system video graphics
test screen
hardware and monitor.
Tests the floppy drive response to
test floppy
commands.
Tests the SCSI interface logic on
test scsi
the system board.
Performs a self-test diagnostic on
test cdrom
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)

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.
