From e50cbe8eb763cf63fb44b047d5164f6fbf07eb39 Mon Sep 17 00:00:00 2001 From: Alejandro Sior Date: Fri, 13 May 2022 20:50:39 +0200 Subject: boot: longmode to realmode stub 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). --- rt/+x86_64/halt.s | 5 +++++ 1 file changed, 5 insertions(+) create mode 100644 rt/+x86_64/halt.s (limited to 'rt/+x86_64/halt.s') diff --git a/rt/+x86_64/halt.s b/rt/+x86_64/halt.s new file mode 100644 index 0000000..72404b3 --- /dev/null +++ b/rt/+x86_64/halt.s @@ -0,0 +1,5 @@ +.globl rt.halt +rt.halt: + cli + hlt + jmp rt.halt -- cgit v1.2.3
