Grub messages

Hi, ok, my kernel is booting, i think, its in the elf format and gets booted by grub but at the mo it doesn't actually do anything (except set-up the broken gdt but that doesn't output anything to know whether it works or not, except i don't tripple fault so that might be a good sign :)). However, when grub loads the kernel it displays some messages that u have never seen come up before.
The message is:
[Multiboot-elf, <0x100000:0x15:0x0>, <0x101018:0x39:0x0>, shtab=0x102140, entry=0x100000]

Guessing, I think this is just some elf header tables output from grub, but since i never seen it before i don't want to continue coding if it is an error and find out my code that never runs doesn't work either.
Could anyone tell me if i should be concerned with this message or not?
Thanks

Regards, Brill

Those are normal grub messages, describing the file format, where it's going to load it, and what not.

From what I can tell (and this is a guess!), here's what they represent:
[format, <start of .code,?,?>, <end of .data,?,?>, end of .bss, entry point]

The second element in the <>'s could, I suppose, be a selector... but, I doubt it.  0x39!?  0x0 could be the base of the selector... they are all supposed to be 0 .. 2^32
