I decided to put some work into booting in hard-drive (DL 0x80). That in itself wasn’t too big an issue, but it in turn made floppy boot (DL 0x00) nonfunctional. I went back and forth, fixing one, breaking the other, again and again. Right now there is some kind of silent failiure in floppy mode that causes it to take minutes to boot (I think its failing and retrying 3 times on every sector) and then it finds the root dir populated as all zeros. The issue is all the processes come back as successes when reading registers. So right now, only hard drive mode works, but this devlog is already wayyyy too long and I wouldnt want to lose all this time.
