Notes
- The minimum OS is 2.5.1 HW: 11/97, 2.6 HW: 5/98, or 7 HW: 8/99.
- The flash PROM is soldered to the system board.
- Use the Flash PROM Programming Utility to update the flash PROM.
- 64-Bit PCI boards do not fit into Slot 4. Connector J3601 interferes with
the 64-Bit PCI extension connector.
- DC-DC Converter 300-1407 connects to J4105 and J4108 on the
system board.
SCSI Bus Notes
- The internal SCSI bus is controlled by /pci@1f,4000/scsi@3.
- The external SCSI bus is controlled by /pci@1f,4000/scsi@3,1.
Memory Notes
- DIMMs are required on both the Riser Board and the System Board.
- Every populated bank must contain four same-size DIMMs. Four
same-size DIMMs are a "quad".
- To activate 2-way interleaving, quads must be installed in
banks 0 and 1, which are non-adjacent banks.
(A third quad may be installed in either remaining bank, but that
will disable interleaving.)
- To activate 4-way interleaving, all four banks must be populated
with quads.
- Each bank addresses 1GB of memory.
- Damage to the Mictor Connectors can occur if DIMMs are installed
or removed when the Riser Board is installed on the System Board.
