There’s also a nyan for BIOS, not only the above UEFI one!
NYAN ALL THE MBRs!
A 16 bit Nyan cat demo small enough to fit in the master boot record of a disk.
BEFORE YOU CONTINUE: USE ON YOUR OWN RISK, PLAYING WITH MBRs IS LIKE PLAYING WITH FIRE. DO NOT BE ON FIRE!
have you ever wanted a moving nyan cat as your bootloader? of course! now you can. the rainbow and cat tail moves as of right now, and work is being done to add stars in the background.
nyan-load code is based on efi-example.
EFI-example: Self-contained minimal example of building an EFI application (under 64 bit Linux atm) without external build dependencies. This project was created to research the base for an EFI bootloader for the Haiku Operating System.
