Hello from Gregg C Levine
Sorry to hear that it went unnoticed on the other list. It looks good
to me. Have you had a chance to test this idea, on a kernel? Here's a
suggestion. If you have the resources that is. Compile a kernel, one
of the latest 2.4.x ones, and apply that collection of statements to
it. There's a method for convincing a Linux kernel to become multiboot
header amendable, but I don't remember it.

Thanks!

Hello,

I have started on trying to create a more extensible boot header.
   

Here is what I have
 

so far:

struct mbv2_header
   {
        unsigned magic;
        unsigned header_addr;
        unsigned load_addr;
        unsigned load_end_addr;
        unsigned bss_end_addr;
        unsigned entry_addr;
        mbv2_flag_t flags;
   };
struct mbv2_flag
   {
        mbv2_flag_t type;
        size_t length;
        char data[0];
   };
typedef mbv2_flag mbv2_flag_t;

Flag is probably not the appropriate term at this point.  But it
   

begs the question.  Are
 

any flags "required" that could not be replaced with this structure?
   

Obviously I am
 

missing the enum for the mbv2_flag_type_t also.

Any thoughts?  As I have said before, I am a n00b so please don't be
   

too harsh on
 

me!! :-)

Thanks,

No I haven't tested it yet.  I am trying to build it into an extensible 
multi-boot header file.

Thanks for the response!
