GCN [Gamecube] Boot SD boot

[KirovAir]

Hi all,
Recently I've modded my gamecube with a XenoGC 1.0 chip. For now, it plays backups fine and all, but I prefer the SD boot way to play games. (I've tested some titles, which are working fine on my Wii, and selecting them with SD boot seems more practical too me)
So practicly I'm searching for a way to boot homebrew with a XenoGC 1.0 chip.

Things I've come around after some searching:
GCOS, which is the gamecube OS? - Can someone explain me more about this one?
SDLoad - This is simply a bootable disk to select homebrew? - Would this be my best shot?

Also, are there any other ways to boot SD boot (or other homebrew) as fast as possible? Like an autoboot disk, that boots xxx.dol from my SD gecko?

As mentioned, I've got a SD gecko available, ofcourse.

Thanks in advance.
