Coreboot Bios Compatibility

[Raziel in Shambles]

Hello,

i'd like to know if it is possible to flash the coreboot bios to my mobo.

If so might i also burden you for a brief tutorial, aside from the one 
provided on coreboot.org, on

how to actually build this bios (f.e. does it need to be i386 or x64, 
howto configure the payload,

is overclocking a possibility etc.).

thx in advance

Good day Raziel, when there is a question about whether a particular
hardware supports coreboot or not, the first thing you could do is to
look through this page :
https://www.coreboot.org/Supported_Motherboards (no GA-MA790GP-DS4H
there). If there is no entry for your motherboard at this page, next
you could git clone the coreboot source code from
http://review.coreboot.org/coreboot/ and do "make menuconfig" command
in the directory with coreboot sources, then go to Mainboard , choose
your Mainboard Vendor ( Gigabyte ) and then check if it is possible to
select your mainboard model - no GA-MA790GP-DS4H also, but there are
GA-MA785GM-US2H / GA-MA785GMT-UD2H / GA-MA78GM-US2H with a somewhat
similar model number. Now, if you don't see your motherboard there,
you may either to simply buy a motherboard from Supported Motherboards
list, or - maybe try to port a coreboot to your motherboard,
especially if its quite similar to the already-supported motherboard.
E.g. check if those GA-MA785 motherboards have the same chipset as
your GA-MA790. If your motherboard contains the components that are
already supported by coreboot, your chances of getting coreboot on
this motherboard are significantly increasing. Please look through
this page for more info -
https://www.coreboot.org/Motherboard_Porting_Guide - and ask if you
need to clarify something. To overclock you probably need to dive deep
into coreboot sources (luckily its in C not assembly) and maybe also
check the OS overclocking tools such as turionpowercontrol for AMD
CPUs which works under Linux. Also,

Check these to see if there is already support for your motherboard:

https://www.coreboot.org/Supported_Motherboards
https://review.coreboot.org/cgit/coreboot.git/tree/src/mainboard

Doesn't look like it, so you'd need to roll your own:

I'll also repeat the advice I always give: BEFORE you start a new, untested
mainboard, follow the entire process of creating coreboot for a known good
mainboard. You'll probably make all the mistakes I still make, and it's
much easier to work on a tested mainboard first.

This is not like installing Linux on a new computer. It's far, far harder.
