NVRAM
(Phaser 840
only)
This test does a walking 1s and a walking 0s test for that
last 4 bytes in the VxWorks section of the NVRAM.
10
EEPROM
This test reads in the first 24 bytes from the EEPROM then
verifies that the Tektronix Ethernet address 0x08, 0x00,
and 0x11 has been copied into three locations.
11
Mariner ASIC
This test reads and verifies the version level of the Mariner
ASIC on the main board.
12
Medusa ASIC
This tests reads and verifies the version level of the
Medusa ASIC on the main board.
13
Super Glue
ASIC
This tests reads and verifies the version level of the Super
Glue ASIC on the main board.
14
CL1284 IC
This tests reads and verifies the version level of the
parallel port controller CL1284 chip on the main board.
17
Ethernet chip
This test verifies the existence of the Ethernet chip on the
main board.
18
TEA error
(Phaser 850
only)
The error occurs during power-up self tests when one of
the main devices previously enabled fails to respond,
unexpectedly causing a TEA. (Normal TEAs cause the
corresponding specific error.) This could be caused by
either the Code ROM or Main Board.
none
SCSI
(Phaser 840
only)
This test verifies the functionality of the SCSI I/O
processor. Any test failures with this component are
treated as non-fatal errors with the error information
written to the Startup Page. If a failure is detected, the
message “SCSI Option Card:” with one of the following
messages will be sent to the Startup Page.
■
Wrong values in script-set scratch registers.
■
Script operation timed-out.
■
Script operation returns wrong exit code.
■
DMA transfer spills outside buffer.
■
DMA transfer data mismatch.
none
IDE hard drive
This test verifies that the main board is able to
communicate with the IDE drive.
