Notes

  1. The minimum OS is 2.5.1 HW: 11/97, 2.6 HW: 5/98, or 7 HW: 8/99.
  2. The flash PROM is soldered to the system board.
  3. Use the Flash PROM Programming Utility to update the flash PROM.
  4. 64-Bit PCI boards do not fit into Slot 4. Connector J3601 interferes with the 64-Bit PCI extension connector.
  5. DC-DC Converter 300-1407 connects to J4105 and J4108 on the system board.

SCSI Bus Notes

  1. The internal SCSI bus is controlled by /pci@1f,4000/scsi@3.
  2. The external SCSI bus is controlled by /pci@1f,4000/scsi@3,1.

Memory Notes

  1. DIMMs are required on both the Riser Board and the System Board.
  2. Every populated bank must contain four same-size DIMMs. Four same-size DIMMs are a "quad".
  3. 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.)
  4. To activate 4-way interleaving, all four banks must be populated with quads.
  5. Each bank addresses 1GB of memory.
  6. Damage to the Mictor Connectors can occur if DIMMs are installed or removed when the Riser Board is installed on the System Board.
