im still working on real hw boot issues. coil doesnt guess geometry anymore, it brutes it: the new stage2 tries every plausible CHS geometry against a buildtime checksum of the kernel’s first sector and prints the one that actually works. no more “trust the BIOS” and no more “reject the BIOS”, just prove it. on a sane machine it prints g(18.2) and boots like nothing happened. on the laptop it either prints its real geometry and boots, or prints G! plus what the BIOS claimed. either way i finally get an answer instead of a silent reset. in the meantime ill be working on some features like arrows, logging, etc. attached photo of my testing setup
