While still very impressive, this does make use of BIOS routines for VGA, I/O and timekeeping.

- userbinator 7y ago...as opposed to something much bigger that also eventually uses the same "library" of functionality.
- basementcat 7y agoI would be interested in seeing if an EFI version of this would also fit in 512 bytes. One may have to overlap some fields in the binary format.
- nineteen999 7y agoDoes EFI even have the same 512 byte restriction though?
- NieDzejkob 7y agoNo, it doesn't.
- einr 7y agoAs for VGA, it only uses one BIOS call to set the graphics mode, then never again. After that, it just throws bytes directly at VGA memory.
