Revision as of 11:34, 2 December 2014
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.
Contents
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.
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
