GRUB2 configuration with linux long mode kernel

[jamesread]

I made a linux compatible long mode kernel by copying a number of files from the linux source code and was able to compile it and run it in qemu. Here is a screen shot from qemu in legacy mode:

I am bit confused by the output. Here is my grub.cfg file:

Code: Select all

set timeout=15
set default=0 # Set the default menu entry

menuentry "MYOS" {
   linux /boot/kernel-file root=sr0
}

I set root=sr0 as the ouput suggests but still getting the same kernel panic.

Did you copy the parts that handle the partition table and filesystem on your disk?

[jamesread]

I don't think so. I was aiming for a bare minimum.

How is it supposed to mount that filesystem without the code for reading that filesystem?
