If a node repeatedly and spontaneously reboots when attempting to load the InfiniPath driver, it may be a symptom that its InfiniPath interconnect board is not well seated in the HTX or PCIe slot.

Some HTX Motherboards May Need 2 or More CPUs in Use

Some HTX motherboards may require that 2 or more of the CPUs be in use for the HTX InfiniPath card to be recognized. This is most evident in four-socket motherboards.

C.2

BIOS Settings

This section covers issues related to improper BIOS settings.The two most important settings are:

■ACPI needs to be enabled

■MTRR mapping needs to be set to “Discrete”

If ACPI has been disabled, it may result in initialization problems, as described in appendix C.4.4.

An improper setting for MTRR mapping can result in reduced performance. See appendix C.2.2, appendix C.2.3, and appendix C.2.3 for details.

NOTE: BIOS settings on IBM Blade Center H (Power) systems do not need adjustment.
