ASRock H110M-DVS

This page describes how to run coreboot on the ASRock H110M-DVS.

Required proprietary blobs

Mainboard is based on Intel Skylake/Kaby Lake processor and H110 Chipset. Intel company provides Firmware Support Package (2.0) (intel FSP 2.0) to initialize this generation silicon. Please see this document.

FSP Information:

+-----------------------------+-------------------+-------------------+
| FSP Project Name            | Directory         | Specification     |
+-----------------------------+-------------------+-------------------+
| 7th Generation Intel® Core™ | KabylakeFspBinPkg | 2.0               |
| processors  and chipsets    |                   |                   |
| (formerly Kaby Lake)        |                   |                   |
+-----------------------------+-------------------+-------------------+

Please take FSP from the directory 3rdparty/fsp/KabylakeFspBinPkg/ in the coreboot or download the latest version from github.

You must use Intel Binary Configuration Tool BCT to set the following parameters in FSP.fd to initialize the PEG x16 port:

Peg0Enable = Enable
Peg0MaxLinkSpeed = Gen3
Peg0MaxLinkWidth = Auto

BCT creates Fsp_M.fd, Fsp_S.fd and Fsp_T.fd. These files are integrated into the coreboot image. If PEG port is not used, you can get these files without BTC:

# split FSP.fd
python 3rdparty/fsp/Tools/SplitFspBin.py split -f 3rdparty/fsp/KabylakeFspBinPkg/Fsp.fd

Building coreboot

The following steps set the default parameters for this board to build a fully working image:

make distclean
touch .config
./util/scripts/config --enable VENDOR_ASROCK
./util/scripts/config --enable BOARD_ASROCK_H110M_DVS
./util/scripts/config --enable CONFIG_ADD_FSP_BINARIES
./util/scripts/config --set-str CONFIG_FSP_M_FILE "/path/to/Fsp_M.fd"
./util/scripts/config --set-str CONFIG_FSP_S_FILE "/path/to/Fsp_S.fd"
./util/scripts/config --set-str REALTEK_8168_MACADDRESS "xx:xx:xx:xx:xx:xx"
make olddefconfig

However, it is strongly advised to use make menuconfig afterwards (or instead), so that you can see all of the settings.

Use the following command to disable the serial console if debugging output is not required:

./util/scripts/config --disable CONSOLE_SERIAL

However, a more flexible method is to change the console log level from within an OS using util/nvramtool, or with the nvramcui payload.

Now, run make to build the coreboot image.

Flashing coreboot

Internal programming

The main SPI flash can be accessed using flashrom. By default, only the BIOS region of the flash is writable. If you wish to change any other region, such as the Management Engine or firmware descriptor, then an external programmer is required (unless you find a clever way around the flash protection). More information about this here.

External programming

The flash chip is a 8 MiB socketed DIP-8 chip. Specifically, it's a Macronix MX25L6473E, whose datasheet can be found here. The chip is located to the bottom right-hand side of the board. For a precise location, refer to section 1.3 (Motherboard Layout) of the H110M-DVS manual, where the chip is labelled "64Mb BIOS". Take note of the chip's orientation, remove it from its socket, and flash it with an external programmer. For reference, the notch in the chip should be facing towards the bottom of the board.

Known issues

  • The VGA port doesn't work.

  • PEG x16 port training correctly runs only at link speed of 2.5GT/s(gen1). It takes more time to research the schematic of this board.

  • SuperIO GPIO pin is used to reset Realtek chip. However, since the Logical Device 7 (GPIO6, GPIO7, GPIO8) is not initialized, the network chip is in a reset state all the time.

Untested

  • parallel port
  • PS/2 keyboard
  • PS/2 mouse
  • EHCI debug
  • TPM
  • infrared module
  • chassis intrusion header
  • chassis speaker header

Working

  • integrated graphics init with libgfxinit (see Known issues)
  • PCIe x1
  • PEG x16 Gen1 (see Known issues)
  • SATA
  • USB
  • serial port
  • onboard audio
  • using me_cleaner
  • using flashrom

TODO

  • PEG x16 Gen3
  • NCT6791D GPIOs
  • onboard network (see Known issues)
  • S3 suspend/resume
  • Wake-on-LAN
  • hardware monitor
