Thanks Corey,
- I agree that before reading through the code, it is better to first
check
if the BIOS guides are available. However I would still like the
answer to
my question if I wish to carry on with the investigation for now.
- I am trying to work out an overview of the changes required for a
start; a
bird’s eye view of what the changes could turn out to be. What is the
best
approach for this?
You will have to write "drivers" for all your components.
- Northbridge (integrated into CPU these days)
- Southbridge
- CPU
- Super I/O / Embedded Controllers / Management Engine
- ...
Starting a new chipset port for a chipset of that complexity is probably going to be 6 months to a year of work
I also seem to remember something about the iX CPUs having a different bus setup for the multiple northbridges, but I don't remember the specifics, and never looked into what changes might be needed to coreboot.
