2.5 FORTH-Based PROM Diagnostics
For information about how to run the FORTH Diagnostics, see Appendix D,
“FORTH Diagnostics.” Table 2-4 lists specific on-board diagnostic tests for
SPARCstation 5 systems.
Table 2-4 Selected FORTH Diagnostic Tests
Type of Test Description Preparation When to Use
test screen Tests the system video graphics
hardware and monitor.
The diag-switch? NVRAM
parameter must be set to true.
See description.
test floppy Tests the floppy drive response to
commands.
Insert a formatted diskette into
the drive.
See description.
test scsi Tests the SCSI interface logic on the
system board.
The diag-switch? NVRAM
parameter must be set to true.
See description.
test net-aui Performs an internal and an external
loopback test on the AUI (Thick)
Ethernet interface.
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.
See description.
test net-tpe Performs an internal and an external
loopback test on the twisted-pair
Ethernet (TPE) interface.
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.
See description.
test net Performs an internal and an external
loopback test on the auto-selected
system Ethernet interface.
A cable must be attached to the
system and to an Ethernet tap or
hub or the external loopback test
will fail.
See description.
test disk
test disk0
test disk1
test disk2
test disk3
Tests internal or external SCSI disks
that have a self-diagnostic program
contained in the drive controller
(disk0 = SCSI address 0, disk1 =
SCSI address 1, disk2 = SCSI
address 2, disk and disk3 = SCSI
address 3).
The drive must be spinning
before this test is executed or the
test will fail. Enter a boot <disk
alias> command to cause the
drive to spin up.
Disk drive does not
function properly.
