Implication Users cannot disable onboard video via BIOS Setup
Status This errataum was fixed in BIOS revision R0057.
Workaround Adding in a video controller automatically disables the onboard video. It is not
necessary to manually disable the video controller via BIOS setup. There is no
workaround for configurations that do not include video controller support.
28. The SMBIOS entry point may not be visible under certain hardware
configurations
Problem The server BIOS maintains an area in memory to act as an entry point to locate
the SMBIOS area. This entry point includes the anchor string “_SM_”, memory
pointers and information about the SMBIOS area as required by the SMBIOS
specification. This information is dynamically created by the BIOS during POST
and is placed in a required memory range between 000F0000h-000FFFFFh.
Hardware configurations that require large amounts of memory at POST
(option ROM space or I/O configuration space) could fill up this memory range
and the SMBIOS entry point cannot be created correctly.
Implication This problem manifests as an inability for software to locate the SMBIOS
records. This can affect management software and also some Intel-provided
update utilities including BIOS update utilities and FRUSDR update utilities. An
error may also display in the BIOS error manager. Intel update utilities will
generate an error and abort before performing an update.
Status This erratum is fixed in BIOS release R0060 and later release.
Workaround If a specific hardware configuration experiences this issue, remove add-in PCI
and PCIe cards to reduce the amount of add-in card resource space used.
Perform the system update (BIOS, FRUSDR) and replace the add-in cards.
29. Fans occasionally running too fast after BIOS reset
Problem From the BIOS setup screen, when you hit F10 to save and reset, the PWM will
often come up at 30 hz instead of 23 kHz. Fan are running too fast in this mode.
Hitting the Reset button causes the fan speed to return to normal.
Implication If users do not perform a hard reset from the front panel, the fans in the system
may run too fast and cause unnecessary noise.
Status This erratum is fixed in BMC Revision 49 and later releases.
Workaround In order to work around this issue, you must execute a hard reset from the front
panel. This resets the PWM circuitry back to the correct frequency.
