[PATCH] Improve FreeDOS direct loading support compatibility.

[C. Masloch]

Hello,

A bit about me first; feel free to skip this paragraph. I know 86 assembly  
language well and have been involved in FreeDOS kernel development. On the  
freedos-user list I read that GRUB 2.00 added FreeDOS direct loading  
support. I have reviewed GRUB's implementation of the FreeDOS load  
protocol.

The attached patch improves compatibility to the FreeDOS kernel and its  
original loader as well as potential compatibility to other DOS-like  
kernels and loaders. In particular, some requirements of the current  
EDR-DOS load protocol are implemented by this as well (though possibly not  
all of them) without harming the loading of FreeDOS kernels.

Regards,
Chris Masloch
