Zorya BIOS
Zorya BIOS is an extendable and configurable BIOS and bootloader, capable of booting any OS with the right extensions. It's similar to GRUB.
(sorry in advance for bios.lua)
All you need to install the BIOS is to flash bios.lua to a blank EEPROM, insert a blank floppy, then reboot. Note: This has only been tested on Tier 3 hardware and Lua 5.3. requires an Internet card.
