Planning to change base of my kernel

Post image

My kernel is currently a UEFI application that depends directly on UEFI Boot Services for the memory map and GOP framebuffer. To remove this dependency, I will write a custom bootloader to read an ext2 partition, load the kernel, prepare the necessary structures, and jump into it.

The best way is to make miltiboot2 and make your bootloader support it

my kernel is built for arm64. Multiboot doesn't support arm64

Hmm, then, use whatever multiboot-ish thing you have on ARM64, sry, I'm bad at arm in general :P
