Notes

  1. The Sun 4400 CPU requires EPROM 3.0 or greater to support the 128MB memory board.
  2. SunOS 4.0.3 supports up to 256MB of memory.
  3. SunOS 4.1 PSR A requires 4.1 PSR A Sun-4 PMEG Patch to enable over 256MB of memory.
  4. A Correctable Error on the sixth 128MB board turns on the CE LED and turns off error logging. Reset power to clear this condition.
