bootinfoscript may be a starting point.

Thanks Andrey,

I know it and after seeing that I wondered if there was something simpler...
With bootinfoscript you really need to dig the two stages... I would avoid to read bootinfoscript to understand how they are structured.

One of the end goals, beyond those I have already mentioned, is to understand how grub can boot from a LVM logival volume.

I guess the code in the 32kbytes has the capablity to speak LVM, am I right?

Is there at lest a document that explains how that code of the 2nd stage is structured? Or the only reference is to dig the grub code?
