Loading a kernel header in grub2 - ChrisLucas29 - 2018-10-31 14:39

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?

ipxe.efi works its a x86

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