Vladimir adapted SeaBIOS so it=E2=80= =99s 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 command=C2=B9, 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 =C2=B9 By the way, the command `multiboot` and `multiboot2` are not listed in the overview of the GRUB manual [1].
