+# Gigabyte GA-G41M-ES2L rev 1.1
+
+This page describes how to use coreboot on the [Gigabyte GA-G41M-ES2L rev 1.1](https://www.gigabyte.com/Motherboard/GA-G41M-ES2L-rev-11) mainboard.
+
+This motherboard [also works with Libreboot](https://libreboot.org/docs/install/ga-g41m-es2l.html).

+## Preparation
+
+```eval_rst
+For more datails how to get sources and build the toolchain, see :doc:`../../tutorial/part1`.
+```
+
+### Devuan 4 Chimaera
+
+This probably works also for any fresh Debian/Ubuntu-based distros.
+
+Install tools and libraries needed for coreboot:
+
+```shell
+sudo apt-get -V install bison build-essential curl flex git gnat libncurses5-dev m4 zlib1g-dev wget python2 python-is-python2 flashrom
+```
+
+### Get sources
+
+You need about 700 MB disk space for sources only and ~2GB disk space for sources + build results
+
+```shell
+git clone --recursive https://review.coreboot.org/coreboot.git
+```
+
+### Build toolchain
+
+Your system compilers can be different with versions, tested by coreboot developers.
+So, it is recommended to build cross-compilers with special versions, which were tested with coreboot.
+
+It is possible to skip this time-consuming part and use `ANY_TOOLCHAIN=y`, but this not recommended.
+
+You can build them for all platforms: `make crossgcc CPUS=2` but this takes ~2 hours with Intel core2duo E8400.
+
+The best way, probably, is to build cross-compilers for your platform (this takes ~20 minutes with Intel core2duo E8400):
+
+```shell
+make crossgcc-i386 CPUS=2
+```
+
+### Save MAC-address of internal LAN
+
+Run `ip -c link show`, you will find MAC-address like 6c:f0:49:xx:xx:xx
+
+```
+1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
+ link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
+2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+ link/ether 6c:f0:49:xx:xx:xx brd ff:ff:ff:ff:ff:ff
+```
+
+## Configure
+
+Create file `payloads/external/SeaBIOS/.config_seabios`:
+
+```shell
+CONFIG_COREBOOT=y
+CONFIG_ATA_DMA=y
+CONFIG_VGA_COREBOOT=y
+```
+
+Edit file `configs/config.gigabyte_ga-g41m-es2l`, replace `CONFIG_REALTEK_8168_MACADDRESS` value with your MAC-address.
+
+Run
+
+```shell
+make defconfig KBUILD_DEFCONFIG="configs/config.gigabyte_ga-g41m-es2l"
+```
+
+## Build
+
+Just execute:
+
+```shell
+make
+```
+
+It takes ~2 minutes with Intel core2duo E8400.
+
+Example of last part in the output:

+
+## Flashing coreboot
+
+```eval_rst
+In addition to the information here, please see the
+:doc:`../../flash_tutorial/index`.
+```
+
+### Do backup
+
+The above commands read the SPI flash chip(s), write into file and then verify content again with the chip:
+
+```shell
+sudo flashrom -p internal:dualbiosindex=0 -r m_bios.rom
+sudo flashrom -p internal:dualbiosindex=0 -v m_bios.rom
+sudo flashrom -p internal:dualbiosindex=1 -r b_bios.rom
+sudo flashrom -p internal:dualbiosindex=1 -v b_bios.rom
+```
+
+If access error appeared, then add `iomem=relaxed` to Linux kernel parameters and restart your Linux system.
+
+You can also repeat backup and compare checksums manually.
+
+Backup file should be stored elsewhere, so that in case the coreboot build is faulty, some external procedure can be used without having to extract the backup from the target device first.
+
+### Write new flash image
+
+Let's write new image into SPI flash chip, verify checksum again and erase second flash chip:
+
+```shell
+sudo flashrom -p internal:dualbiosindex=0 -w build/coreboot.rom
+sudo flashrom -p internal:dualbiosindex=0 -v build/coreboot.rom
+sudo flashrom -p internal:dualbiosindex=1 -E
+```
+
+## Set text mode for GRUB
+
+Update your `/etc/default/grub` with:
+
+```shell
+GRUB_TERMINAL=console
+```
+
+And recreate GRUB configuration `/boot/grub/grub.cfg` by command
+
+```shell
+sudo update-grub
+```
+
+## Boot with new firmware
+
+Restart your system:
+
+```shell
+sudo shutdown -r now
+```
+
+If it is needed, use <kbd>Esc</kbd> key to choose boot device.
+
+Remove `iomem=relaxed` from Linux kernel parameters.
+
+Enjoy!
+
