Hi everyone.

I'new here and probably some of my questions may be kind of stupid.

I'm trying to understand the boot processo of an old computer I have, and
the plan is to port coreboot to it.

My first question is. Where in the firmware binary can I find the first
instrucional tha will be executed ?
I have a dump of the BIOS that I did using a BIOS Programmer (tl866), and
I'd like to start to understand what is hapening.
I know the first instrucion the system execute is the reset vector located
at 0xfffffff0.
Does this mean the first instrucion on the firmware image is at BIOS top -
reset vector ? (0xffffffff - 0xfffffff0)

Thanks for the help
Rafael Machado
