Appendix C RAID Controller Considerations
Factory-Default Option ROM Settings
Factory-Default Option ROM Settings
Table C-4 describes the option ROM (OPROM) settings for card slots that are made at the factory for
various configurations. The version of the server and the number of CPUs affect the OPROM settings.
Note If an option is listed as “not allowed” in Table C-4, that is because it is not supported in the particular
configuration described in that table row. See the footnotes below the table for more information.
For additional information about RAID controller support, see Supported RAID Controllers and
Required Cables, page C-2.
