BIOS Settings
This section covers issues related to BIOS settings.The most important setting is
Advanced Configuration and Power Interface (ACPI). This setting must be
enabled. If ACPI has been disabled, it may result in initialization problems, as
described in “InfiniPath Interrupts Not Working” on page D-3.
You can check and adjust the BIOS settings using the BIOS Setup utility. Check
the hardware documentation that came with your system for more information.
Issue with SuperMicro
®
H8DCE-HTe and QHT7040
The QLogic adapter may not be recognized at startup when using the Supermicro
H8DCE-HT-e and the QHT7040 adapter. To fix this problem, set the operating
system selector option in the BIOS for Linux. The option will look like:
OS Installation [Linux]
Green ON
Amber OFF
Signal detected and the physical link is up. Ready to talk
to SM to bring the link fully up.
If this state persists, the SM may be missing or the link
may not be configured.
Use ipath_control -i to verify the software state. If
all host channel adapters are in this state, then the SM is
not running. Check the SM configuration, or install and
run opensmd.
Green ON
Amber ON
The link is configured, properly connected, and ready.
Signal detected. Ready to talk to an SM to bring the link
fully up.
The link is configured. Properly connected and ready to
receive data and link packets.
