[LinuxBIOS] First instruction in linuxbios

[Jorge Cardona]

Hi.
I'm new in this, and i'm reading the source and i have a question, which one 
it's exactly the first instruction that the processor execute when the pc is 
booting?, in which file is it?

I don't complete understand the relationship between a normal bios and the 
kernel, i think that the bios it's has to pass some data to the kernel, if 
that's true ¿how exactly is that data passed to the kernel?

In linuxbios, how it's this issue handle?

PD: sorry for my english
Thanks
