Symptom

The Advanced Management Module (AMM) log on Blades and the Integrated Management Module (IMM) chassis/web log on rack mount servers will show the following error:

FW/BIOS, firmware progress (Firmware Error) hang

See the following picture for the IMM System Event Log (SEL) log entry for more details:

Note: With Unified Extensible Firmware Interface (UEFI)/IMM code released in Third Quarter or later 2010, the message is improved to the following:

Error: Error: FW/BIOS, connector (No Op ROM Space) PCI express Slot X fault

Also, see the following picture for the IMM SEL log entry for more details:

The slot number will be identified for the PCI device whose ROM could not run.

Note: The IMM code released in Third Quarter 2010 turns on both the FAULT Light Emitting Diode (LED) and the BRD LED on some systems (System x3850 X5 and System x3690 X5), but turning on the BRD LED is not an expected behavior that will be corrected in a newer IMM code targeted for Second Quarter 2011.

Workaround

Problem was originally discovered on Legacy (non-UEFI) machines and extensive documentation was provided to explain how to resolve the symptoms. Please see reference document resolving_1801-1802_errors.pdf in RETAIN Tip H194252 (MIGR-5078445) for more details; Direct link to document:

BEST PRACTICES FOR RESOLUTION ON UEFI MACHINES:

Follow these steps to try to resolve the error messages:

1. Firmware updates may reduce ROM size requirements, so this may be a solution. Ensure all system and adapter firmwares are at latest levels.
2. Disable the Preboot eXecution Environment (PXE) ROM of on-board NICs
   
   The simplest solution to some PCI Option ROM space errors is to reduce the base system ROM requirements to the minimum necessary. Typically, this can be achieved by disabling the PXE (Network boot) ROM capability of the on-board Ethernet.
   
   Note: This does not disable the device in the operating system, it only disables its capability to perform a network boot.
   
   Select F1 setup, then System Settings, and then Device and I/O settings to enable these options.
   
   
3. Disable all Legacy options ROMs for all devices not booting
   
   To disable Legacy Option ROMs boot the machine and press F1 to enter the UEFI menu.
   
   Select System Settings, then Devices and I/O Ports, and then Enable / Disable legacy ROM execution
   
   If machine is PXE or Storage Area Network (SAN) booting, do not disable the Legacy ROMs for adapters that are actually booting a Legacy (non-Extensible Firmware Interface (EFI)) operating system on the machine
   
4. Changing ROM order
   
   Select F1 setup, then System Settings, and then Device and I/O to change these options.
   
   
5. Move Fibre Channel and Fibre Channel over Ethernet cards to earlier slots as they tend to require more ROM Space and should initialize first to reduce chance of problem occurring
6. PCIe 2.1 spec adapters should be in earlier slots. PCIe 3.0 spec does not need as much Option ROM space due to design changes.

Additional information

The system Power On Self Test (POST) Option ROM space errors are caused by an over-subscription of limited PCI ROM resource space. This space is limited by PC architecture to 128 kilobytes (KB). Any requests that will push the system beyond the 128 KB limit cannot be serviced, and will generate the error messages.

These errors are due to a permanent restriction of legacy PCI ROM space architecture.

The Option ROM Space error only applies when booting a legacy OS on a system with UEFI firmware. UEFI aware operating systems will not be affected by this issue.
