NETWORK INSTALLATIONS
For network installations through NFS, FTP, or HTTP (using a network boot disk or PXE), a driver disk that contains the
bnx2/bnx2x driver may be needed. The driver disk images for the most recent Red Hat and SuSE versions are included.
Boot drivers for other Linux versions can be compiled by modifying the Makefile and the make environment. Further
information is available from the Red Hat website, http://www.redhat.com.
SETTING VALUES FOR OPTIONAL PROPERTIES
Optional properties exist for the different drivers:
• bnx2 Driver
• bnx2x Driver
• bnx2i Driver
BNX2 DRIVER
disable_msi
The disable_msi optional property can be supplied as a command line argument to the insmod or modprobe command.
The property can also be set in modprobe.conf. See the man page for more information. All other driver settings can be
queried and changed using the ethtool utility. See the ethtool man page for more information. The ethtool settings do not
persist across a reboot or module reload. The ethtool commands can be put in a startup script such as /etc/rc.local to
preserve the settings across a reboot.
NOTE: Some combinations of property values may conflict and result in failures. The driver cannot detect all such
conflicting combinations.
This property is used to disable Message Signal Interrupts (MSI), and the property is valid only on 2.6 kernels that support
MSI. On 2.4 kernels, this property cannot be used. By default, the driver enables MSI if it is supported by the kernel. It runs
an interrupt test during initialization to determine if MSI is working. If the test passes, the driver enables MSI. Otherwise, it
uses legacy INTx mode.
