If you'll notice https://github.com/oriansj/M2-Planet/blob/master/seed.M1#L2 It explicitly says it was generated from stage0 https://savannah.nongnu.org/projects/stage0/ Specifically cc_x86 http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage2/cc_x86.s Which was built by M0: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/M0-macro.hex2 Which was built by hex2: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/stage1_assembler-2.hex1 Which was built by hex1: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/stage1_assembler-1.hex0 Which was built by hex0: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/stage1_assembler-0.hex0 Which was the 250byte seed used Well the work started back in 2016 with http://git.savannah.nongnu.org/cgit/stage0.git/tree/Linux%20Bootstrap/hex0.s and http://git.savannah.nongnu.org/cgit/stage0.git/tree/Linux%20Bootstrap/hex0.hex It was written one function at a time, with the arguments passed in registers and careful preservation of everything passed. - Jeremiah Orians
