The QLogic adapter also supports connection to the switch by means of optical 
fibres through optical media converters such as the EMCORE™ QT2400. Not all 
switches support these types of convertors. For more information on the 
EMCORE convertor, see 

Intel

®

 and Zarlink™ also offer optical cable solutions. See 

 and 

 for more information.

To achieve the best performance with QLogic adapters, you need to configure 
your BIOS with specific settings. 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. 

For more information, see 

 and the Troubleshooting section of the QLogic Host Channel 

Adapter and QLogic OFED Software Users Guide. 

Some other BIOS settings can be adjusted for better adapter performance. See 

For specific instructions about BIOS settings, follow the hardware documentation 
that came with your system.

 

The Advanced Configuration and Power Interface (ACPI) BIOS option must 
be enabled.

The x86 Page Attribute Table (PAT) mechanism that allocates Write 
Combining (WC) mappings for the Programmed Input/Output (PIO) buffers 
has been added and is now the default. This was previously a BIOS setting.
