2022-05-20	bios.call: clean and avoid hardcoding the gdt and idt when returning to long ↵	Alejandro Sior
	mode Do not make assumptions on the previous gdt and idt, as well as the state of the flags when operating.
2022-05-19	bios: stub calls interrupt number; simplified bios.ha main interface	Alejandro Sior
	Instead of having the bios.call stub calling a function, make it directly call an interrupt that is changed dynamically by modifying the code at runtime. Simplify the bios.ha interface and document it. Next up: implementing a high level drive interface for the BIOS using BIOS interrupts
2022-05-13	boot: longmode to realmode stub	Alejandro Sior
	This is the initial commit to the repo. It adds all the code. The last proper thing that I got working before committing is calling real mode functions from long mode using a stub. Next up, I would like to implement a disk reader abstraction over the BIOS in order to read form partitions (most notably FAT32).
