"The goal of this 512 byte contest isn't to see who can
do the fanciest thing with the least amount of asm code. Instead,
it's rather practical. It's a real bootsector, and it's meant to be
used by the osdev community. It also isn't being run the same as
these competitions have been in the past.
"Implement in no more than 512 bytes a bootsector that will work
on BOTH FAT12 and FAT16 formatted media. The bootsector must detect
at runtime which filesystem type it is running on and act
appropriately. This bootsector must be self contained; for example,
it cannot load an additional sector to handle FAT16 operations.
"Scan for a file named "OSLOADER " in the root directory.
"OSLOADER is a statically linked 32 bit ELF file. Parse the
headers and load the file accordingly. Several sample files will be
provided at a later date to test your bootsector against. None of
these files will have load addresses above the first megabyte.
"Jump to the ELF entry point.
"Use only instructions available on the i386."
