Manufacturer Notes:
  1. The 40MHz Control Board is not compatible with the SS1000E System Board.
  2. The HOSTID and Ethernet Address are programmed into a 2KB x 8-bit Flash EEPROM in the TMS29F816 at U0201. The TMS29F816 is not field replaceable.
  3. The HOSTID and Ethernet Address are downloaded from the control board to the NVRAM on all system boards during POST.
  4. If the control board EEPROM content is invalid, the values stored in the NVRAM on System Board 0 are used.
  5. The Yellow LED on the keyswitch interface board is ON if the control board EEPROM content is invalid.
  6. Use the update-system-idprom OBP command to download the contents of the NVRAM on System Board 0 to a control board with an invalid EEPROM. OBP 2.11 is required.
  7. Use the following command sequence to invalidate the control board EEPROM:
    ok patch noop call update-system-idprom
    ok patch noop call update-system-idprom
    ok patch call noop update-system-idprom
    Power the system off and remove the Control Board.
  8. Use the following commands to change the NVRAM parameter that defines the location of the master system board:
    ok clear-master-nvram
    ok reset
