Network Installations
For network installations through NFS, FTP, or HTTP (using a network boot disk
or PXE), you may need a driver disk that contains the bnx2x driver. The driver disk
includes images for the most recent Red Hat and SUSE versions. You can
compile boot drivers for other Linux versions by modifying the Makefile and
the make environment. Additional information is available from the Red Hat Web
site:
http://www.redhat.com
Setting Values for Optional Properties
Optional properties exist for the different drivers:
 bnx2 Driver Parameter
 bnx2x Driver Parameters
 bnx2i Driver Parameters
 bnx2fc Driver Parameter
 cnic Driver Parameters
For additional information about the drivers, see the associated README files.
bnx2 Driver Parameter
The disable_msi parameter can be supplied as a command line argument to
the insmod or modprobe command for bnx2.
When set to
1 (enabled), this parameter disables MSI and MSI-X and uses the
legacy INTx mode.
Marvell recommends setting the disable_msi parameter to
1 to always
disable MSI/MSI-X on all QLogic adapters in the system. Issue one of the
following commands:
insmod bnx2.ko disable_msi=1
modprobe bnx2 disable_msi=1
This parameter can also be set in the modprobe.conf file. See the man page
for more information.
