Known ways to update firmware on common hardware
This is a collection of known ways to update your built-in firmware (including BIOS, UEFI and other things like Intel ME) on well known common hardware.
Linux Vendor Firmware Service
fwupd utilizes a firmware database to fetch missing updates for your system and peripherals. Currently the vendor and device coverage is not too broad but it is a good starting point before you dive into vendor specific update procedures.
Servers
Servers, IoT and other devices usually have management systems which also allow you to apply various updates automatically or after downloading a firmware package from the vendor website.
flash-kernel
flash-kernel knows how to install u-boot, device-tree blobs and Linux kernel images and initrds for various ARM boards.
Dell
Many current Dell devices can be updated with fwupd.
