hardware conditional OS boot/load

[lejeczek <peljasz@xxxxxxxxxxx>]

Hi guys.

I hope an expert(or two) could shed some light - I ain't a 
kernel nor hardware expert so go easy on me please - on 
whether it is possible to boot system only under certain 
conditions, meaning: as early as possible (grub?) and 
similarly securely, Linux checks for certain hardware, eg. 
CPU serial no. and continue to load only when such 
conditions are met?

I realize that perhaps kernel devel be the place for such 
questions but seen I'm subscriber here, knowing people here 
are experts of same caliber, I decided to ask.

many thanks, L.
