From 3d6f5132894acf54b1958ae190624fc0a774294f Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 12 Oct 2009 15:59:21 -0700 Subject: [PATCH] mboot: correct the detection of the multiboot header Correct the detection of the multiboot header. The logic for when the header extends past the file was backwards, which broke non-ELF multiboot kernels completely. Apparently they are few and far between. Reported-by: Klaus T. Signed-off-by: H.
