Driver Load Upon System Boot
Upon system boot, the Mellanox drivers will be loaded automatically.
To prevent the automatic load of the Mellanox drivers upon system boot:
1. Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
• The firmware of existing network adapter devices will be updated if the
following two conditions are fulfilled:
• The installation script is run in default mode; that is, without
the option '--without-fw-update'
• The firmware version of the adapter device is older than the
firmware version included with the Mellanox OFED ISO image
Note: If an adapter's flash was originally programmed with an
Expansion ROM image, the automatic firmware update will also
burn an Expansion ROM image.
• In case that your machine has an unsupported network adapter device,
no firmware update will occur and the error message below will be
printed.
