OK... ran into my first major big problem today
I am trying to write my own OS, and have so far completed a boot-loader, kernel with screen output, interrupt handling, malloc() and stuff like that. Now the problem is, I want to design my own file system. The design part is not the problem, but I can't seem to find any information regarding how to do Disk I/O under protected mode. From reading source code, I can see that it will likely entail a lot of "in" and "out" assembler calls. If anybody can help me out with a code snippet that explains this, or a good tutorial on the subject, I would be most appreciative.
Thank you in advance
