How to deal with `multiboot` and compressed files

[Paul Menzel]

Dear GRUB folks,


The payloads for coreboot are normally LZMA compressed, as there is
only little room on a flash ROM chip. Vladimir adapted SeaBIOS so it’s
Multiboot compatible, so that SeaBIOS and the VGA Option can be easily
loaded from the hard disk, and not the flash ROM chip.

Trying to load such a compressed with the multiboot command¹, it does
abort with the message, that the Multiboot header cannot be found.

Is the the multiboot command supposed to be able to deal with
compressed files?

If not, could you please tell me, if there is a way to load such a
compressed file, and how?


Thanks,

Paul


¹ By the way, the command `multiboot` and `multiboot2` are not listed
in the overview of the GRUB manual [1].
