80286 ROM BIOS - open-source code base?
I found kaneton/appendix-bios: IBM AT 80286 BIOS (github.com), but I don't see anything about licensing.
8088_bios
- GPL-3.0 licensed BIOS for Intel 8088 based computers

Past meets present in this $200 mini-laptop with a Intel 8088 chip and 640KB
Just a heads up, it looks like these guys ripped off Serge Kiselev's 8088 BIOS [1].

TinyBIOS – A minimalist open-source BIOS project for fun
There are at least three "real" 8086 BIOSes-- "real" as in they can work on actual hardware rather than just emulators-- available in source form, which might be worth examining.
https://www.phatcode.net/downloads.php?id=101 -- this is a respin of code that apparently originated in the 1980s in sketchy Taiwanese clones, so I think some of the docs are reverse engineered
http://glabios.org/ is an all-new-still-under-development project, but it works well enough for my hobby usage.
https://github.com/skiselev/8088_bios These are more targeted towards some specific hardware projects (Xi8088/Micro8088)
Obviously, being for a simple 8086 mrans they don't have some of the complex chipset config used in a modern PC, and even stuff like "hard disc support" is outsourced (for that, you might consider stuff like the XT-IDE Universal BIOS)
