*	x86/multiboot: rename multiboot.s to head.s	Joursoir	2022-10-07	1	-0/+1
\| \| \| \| \|	"Head" is a more typical name for code that passes control to the kernel.
*	x86/multiboot: add multiboot header	Joursoir	2022-10-07	2	-6/+30
\| \| \| \| \| \|	Unfortunately, GNU AS doesn't perform GCC-like preprocessing. So, to include the multiboot header in the assembly code, we should parse and format it to GAS-style.
*	move multiboot files to special directory	Joursoir	2022-10-04	2	-0/+51

\|
*	x86/boot: transform one-stage to two-stage bootloader	Joursoir	2021-09-28	2	-104/+135
\| \| \| \| \| \|	bootsect.s is first stage bootloader, it loads setup.s setup.s is second stage bootloader, it saves system data and loads kernel to $KERNADDR, then jump to 32-bit startup code

\|
*	x86/boot: add real mode segment constants	Joursoir	2021-09-28	1	-0/+13
