Does coreboot support ASRock H110M-DVS R3.0?

[Alexander Zhang]

Hello,

Does anyone know if coreboot supports the ASRock H110M-DVS R3.0 
mainboard? The documentation doesn't mention the revision number but the 
links are all for the R2.0 board and I can only find R3.0 boards for sale.

Thanks,
Alex

What did you find out about the differences between R2.0 and R3.0?

Kind regards,

From the ASRock website it looks like they have different hardware 
layouts and the OEM BIOS packages are different. The specs are similar 
but slightly different. That's all I know.

Link to R2.0: https://www.asrock.com/mb/Intel/H110M-DVS%20R2.0/

Hi,

According to the pictures, R2.0 differs from R3.0 by the number of PCIe
slots
(maybe some ports will not work) and it looks like they are using a
different
SuperIO chip (you may not see the console in the COM port), maybe there are
other differences... Regardless, you can try to run coreboot on your board,
although I recommend analyzing the pad configuration using inteltool (get
a dump of the registers of the gpio controller):

$ sudo ./inteltool -G

and then compare this with the dump from R2.0 -

If there are differences, then you need to fix them in
https://github.com/coreboot/coreboot/blob/master/src/mainboard/asrock/h110m/...

This will avoid possible burnout of chips, transistors or any other
elements on
the board.

Thanks for the information. I don't have a board with me since I was 
just considering buying one that's compatible with coreboot. It looks 
like none of the other boards are suitable for my purposes unfortunately.

Best regards,
