Oracle^® Server X5-2L Product Notes

Option ROM space might run out when server uses Legacy BIOS Mode and Oracle 10Gb Ethernet Adapter cards are installed

Bug ID 22083224

Issue: The Oracle Server X5-2L supports up to four Oracle 10Gb Adapter Cards. In Legacy BIOS Mode, one or two cards must be installed in slots 4 and/or slot 5, and any card installed in slots 1, 2, or 3 must have their option ROM disabled. As a result, some of the cards or ports will not be listed in BIOS as available for booting over the network. This issue does not occur when the Oracle Server X5-2L is running in UEFI Mode.

Affected hardware: Oracle 10Gb Ethernet Adapter Cards

Workaround: Do one of the following:

• If you have encountered this situation, you can obtain Option ROM space by disabling cards and ports that are listed as available for booting over the network, but that are not actually used for booting:

  1. Boot the server from the SP by issuing the reset /System or start /System command.

  2. During the system boot process, press F2, when prompted, to access the BIOS Setup Utility.

  3. Navigate to the IO tab, and press Enter.

  4. From the options that are displayed, select Add In Cards, and then select Slot Number.

  5. To disable the slot, select Disable.

  6. Press the Esc key to return to the main BIOS Setup Utility menu, and select Exit.

  7. To save your changes, select Save Changes and Exit.

     You will now have Option ROM space, and the Oracle 10Gb Ethernet Adapter card will now be listed as available for booting over the network.

• If you have not yet encountered this situation and would like to prevent it from occurring, you can disable 64-bit resource allocation:

  1. Boot the server from the SP by issuing the reset /System or start /System command.

  2. During the system boot process, press F2, when prompted, to access the BIOS Setup Utility.

  3. Navigate to the IO tab, and press Enter.

  4. From the options that are displayed, select PCI Subsystem Settings, and then select PCI 64 bit Resources.

  5. To disable the PCI 64-bit resource allocation, select Disabled.

  6. Press the Esc key to return to the main BIOS Setup Utility menu, and select Exit.

  7. To save your changes, select Save Changes and Exit.

     The server will now maintain enough Option ROM space to list which Oracle 10Gb Ethernet Adapter cards and their ports are available for booting over the network.
