sorry I'm typing on a laptop and my thick vingers hit something and  off, the email,  went.
. It seems almost to simple to be true?
. Looking thru corebootsrc/mainboard I see so many files per mainboard  that I'm (even more) confused There has been a lot of work to produce those files

.  what I have not found yet is where are the ( ??DT) acpi tables in seabios? do  i need to extract those en use the cbfstool to put them in the rom?
. I'm trying to get my machine working with a free open source bios I'm not looking into bug fixing (yet)

Thanks Rene

I have been trying to make a coreboot rom and have a few questions c.q. confirmations. 

As far as I understand the process

 . Coreboot has to initialize the memory to 32bit flatmode and call in layout.S:entry_elf(). see https://www.seabios.org/Execution_and_code_flow
 . seabios starts and does it's magic
 . seabios starts the linux kernel According to the linux bootprotocol (Documentation/x86/boot.rst)

The linux kernel runs my computer perfect so many answers could be answered by the kernel source.
as the same held for seabios and intel documentation
 
 . Linux drivers/i2c/busses:
 .. i2c-i801.c
 .. i2c-smbus.c
 . Linux arch/x86/boot:
 .. main.c
 .. pm.c
 . Seabios
 .. docs/memory_model.md
 . Intel® 965 Express Chipset Family
 .. 82p965.pdf Is this the correct file?
