This page describes how to use coreboot on the Lenovo G505S mainboard.

This page is a work in progress. ACPI is still being worked on, however due to the nature of ACPI it may take some time to get this right.

Known Issues

  • S3 Suspend/Resume - You will need a Console verbosity set to at least "BIOS_INFO" or greater for it to work! Coreboot is likely too fast for the Embedded Controller firmware on the S3 resume hot path.
  • "AGP: Please enable the IOMMU option in the BIOS setup" showing up in dmesg - Pass iommu=noaperture to the kernel boot args to ask the IOMMU not to touch the aperture for AGP.

Overview

Hardware

  • AMD A-series AMD A10-5750M APU
  • AMD AGESA Hudson part of the chipset, AMD AGESA Hudson southbridge
  • ENE KB9012 EC However we use the ENE932 EC driver in coreboot's tree.

Details

...

  • 1x MXIC MX25L1606E (SO8, soldered) 16 Mbit SPI flash (BIOS)

Building a coreboot image

Make a fresh clone of Coreboot into a empty directory and run:

make crossgcc-i386

Make a cup of tea.. Then run:

make menuconfig

and select Lenovo/G505S under "Mainboard -> Mainboard vendor/model" leaving everything else as defaults. Then finally do,

make

To flash the board with flashrom externally run:

flashrom -p ft2232_spi:type=2232H,port=A -w build/coreboot.rom

and internally run:

flashrom -p internal:laptop=force_I_want_a_brick -w build/coreboot.rom
