Configuration and Startup

BIOS Settings

A properly configured BIOS is required. The BIOS settings, which are stored in non-volatile memory, contain certain parameters characterizing the system,. These parameters may include date and time, configuration settings, and information about the installed hardware.

There are currently two issues concerning BIOS settings that you need to be aware of:

■ACPI needs to be enabled

■MTRR mapping needs to be set to “Discrete”

MTRR (Memory Type Range Registers) is used by the InfiniPath driver to enable write combining to the InfiniPath on-chip transmit buffers. This improves write bandwidth to the InfiniPath chip by writing multiple words in a single bus transaction (typically 64). This applies only to x86_64 systems.

However, some BIOSes don’t have the MTRR mapping option. It may be referred to in a different way, dependent upon chipset, vendor, BIOS, or other factors. For example, it is sometimes referred to as "32 bit memory hole", which should be enabled.

If there is no setting for MTRR mapping or 32 bit memory hole, please contact your system or motherboard vendor and inquire as to how write combining may be enabled.

ACPI and MTRR mapping issues are discussed in greater detail in the Troubleshooting section of the InfiniPath User Guide.

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