The framework of it maybe, but it is tailored to the board, doing the low
level initialization of things like the ram controler, the layout off the
different buses in main memory and stuff like that.

The important thing is that even if there is a common base for the code, it is
modified to fit the board, and contains information about the boards layout
(what chip is connected where and so on), and that it will come from the board
vendor and not from a third party.

For example, if you want to upgrade your bios on your random motherboard, you
don't go to microsoft, and you don't go to phoenix or similar, but you go to
asus or whoever made your board to download the upgraded firmware and its
flash tool.

The firmware is linked to the layout of the flash chip holding it, and the
boot method chosen for the board, and is thus done by the same folk who do the
schematics for the board, and produce it.
