NAME

fw_updateinstall non-free firmware packages

SYNOPSIS

fw_update [-adinv] [-p path] [driver ...]

DESCRIPTION

The fw_update utility installs, updates, or deletes firmware packages for driver from the Internet. If no driver is specified, the fw_update utility tries to determine which firmware is needed on the system.
Since firmware with an acceptable license is already present in OpenBSD, fw_update exists purely to deal with firmware that may not be freely distributed with OpenBSD.
The options are as follows:
 
 
-a
Install or update firmware for all drivers. It is an error to specify this option with any driver arguments.
 
 
-d
Delete firmware for driver. If used without parameters, delete all firmware that is not required by a driver. If used in conjunction with -a, delete firmware for all drivers.
 
 
-i
Display information about firmware which is installed or missing, and whether it appears to be required by a driver.
 
 
-n
Dry run. Do not actually install or update any firmware packages; just report the steps that would be taken.
 
 
-p path
Use the firmware found at path, being either a local directory or a URL, instead of the default location.
 
 
-v
Turn on verbose output. This flag can be specified multiple times for increased verbosity.
Firmware is downloaded from release-specific directories at http://firmware.openbsd.org/firmware/. The files are in the format required by pkg_add(1), but direct use of pkg_add is discouraged.
