Hi,
I've written my own code for grub2 boot rom, the steps are:
1, Use make to compile romboot.S and grub-mkrom.c, it will generate
romboot.img and grub-mkrom.
2, Create kernel image core.img with grub-mkimage
3, Create rom image with grub-mkrom, like this:
grub-mkrom romboot.img core.img output_file
grub-mkrom support the following options:
-m message Boot message
-t timeout Timeout in seconds
-k key Hotkey
-x edx Value of EDX
default hotkey is SPACE, default timeout is 2 seconds.
The new code is much smaller than the romos version (only 240 bytes),
and it runs grub2 after POST, so that int 13 can be used to access the
disk.
