FW_UPDATE(1) General Commands Manual FW_UPDATE(1)

fw_update
install non-free firmware packages

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

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 are needed on the system.
Since firmware with acceptable licenses are 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:
 
 
Install or update firmware for all drivers. It is an error to specify this option with any driver arguments.
 
 
Delete firmware for driver. If used in conjunction with -a, delete firmware for all drivers.
 
 
Dry run. Do not actually install or update any firmware packages; just report the steps that would be taken.
 
 
path
Use the firmware found at path, being either a local directory or a URL, instead of the default location.
 
 
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.
