[Qemu-devel] [PATCH] multiboot support

[Alexander Graf]

Hi,

this patch adds very simple multiboot support for x86 as defined in  
http://www.gnu.org/software/grub/manual/multiboot/ using the -kernel  
switch.

There is no support for modules or command line parsing, as it would  
be required by XEN or HURD, but simple OSs already work when used in  
conjunction with this patch.
Adding module support should be as simple as writing the modules into  
RAM and setting some information fields in the bootinfo structure (if  
anyone's interested in booting more than linux without a full-blown  
bootloader).

The only one I have tested so far is the boot2 darwin bootloader  
modified to work using multiboot by David F. Elliott, which worked  
fine bringing up first parts of a stock osx kernel.

I believe this patch does not break anything and is safe to be  
applied, whereas comments are (as always) welcome though.

Cheers,

Alex
