Loading a kernel header in grub2

[ChrisLucas29]

Hello,

I've created a .lkrn file via this command:

Code:

make bin/ipxe.lkrn

And I'm trying to boot it via the grub shell but It keeps freezing and I'm not getting any error mesages. Here is the code in grub2:

Code:

exec tail -n +3 $0
menuentry "Netboot"{
linux /boot/ipxe.lkrn
}

So you are booting in legacy pcbios mode and gets a hang?
How/where was grub booted from? Was it from disk?

1. My device a EFI 32-bit. Must it be a legacy BIOS
2. It's using an micro SD card to boot

ipxe.lkrn can only boot in pcbios mode.
please try ipxe.efi instead.
it is x86 and not ARM right?

[ChrisLucas29]

ipxe.efi works its a x86

What's pcbios mode?

Pcbios or legacy mode is the usual boot for x86 when not using efi.
