Laptops with coreboot Support

Embedded controllers

The remaining issue with supporting netbooks may be open firmware support for the Embedded controller (EC). These ECs used to support keyboard scan, lid open/closed, battery charging, power management, etc.

coreboot should work with the "stock" EC firmware. This may still be a challenge because "we don't know what we don't know". Behavior at runtime is fairly standardized, but we don't know what we need to do for initialization - do we need to set up registers, put in tables, kick things, or will it all Just Work (TM)?

HOWTO to find a way

  • find a model and manufacturer of your laptop
  • download these tools:
 # git clone http://review.coreboot.org/p/coreboot
 # superiotool (  cd coreboot/util/superiotool ; make ; sudo make install )
 # inteltool ( cd coreboot/util/inteltool ; make ; sudo make install )
 # ectool ( cd coreboot/util/ectool ; make ; sudo make install )
 # dmidecode ( cvs -z3 -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/dmidecode co dmidecode )
 # msrtool ( cd coreboot/util/msrtool ; make ; sudo make install )
 # nvramtool ( cd coreboot/util/nvramtool ; make ; sudo make install )
 # flashrom ( svn co svn://coreboot.org/flashrom/trunk flashrom )
  • make and install them (make; sudo make install) - you need at least libpci/pciutils
  • check that your distro have this tools and install them:
 # lspci
 # dmesg
 # acpitool
 # lspnp
 # lsusb
  • Do this commands:
 # lspci -nnvvvxxxx > lscpi.log
 # lspnp -vv > lspnp.log
 # lsusb -vvv > lsusb.log
 # superiotool -deV > superiotool.log
 # inteltool -a > inteltool.log
 # ectool > ectool.log
 # msrtool > msrtool.log
 # dmidecode > dmidecode.log
 # biosdecode > biosdecode.log
 # nvramtool -x > nvramtool.log
 # dmesg > dmesg.log
 # flashrom -V -p internal:laptop=force_I_want_a_brick > flashrom_info.log
 # flashrom -V -p internal:laptop=force_I_want_a_brick -r rom.bin > flashrom_read.log
  • Save all logs in safe place, and also rom.bin file.
  • try to find information - what EC or Super I/O chip is used in your laptop (may be some info in Service Manuals or Disassembly guides)
  • if you see that ectool return some fake staff - like only 'FF' or '00' - so you have custom EC configuration, it's a hard work for support
  • if you see that ectool return looks like 'right' output - you have a big chances for support
  • you need to find from thease outputs Super I/O / EC chip name, or if not see this - disassembly your laptop
  • try to find your Super I/O / EC chip datasheet

This not a list of coreboot supported laptops. This page only lists the chipsets, Super I/Os, flash chips, and especially embedded controllers used in a few laptops, just for reference purposes.

1 According to the vendor BIOS update tool.
2 Nice thing: EC/Flash is not shared, so you can erase the whole flash during system operation (this was tested).

Mailinglist discussion

A few earlier coreboot discussions on laptops are linked here, you might get useful information out of them:

Who really makes your laptop?

There are several various brands of laptops, but there are only a few actual laptop makers.

Name brand companies like Hewlet Packard, Compaq, IBM, Dell, Gateway, Sony, Micron, Toshiba and others; including Alienware and Voodoo do not make their own laptops. The exceptions are Asus and Apple, and even Apple doesn't make all of their laptops.

Original Design Manufacturers (ODM) make the laptops for Original Equipment Manufacturers (OEM). They in turn, add their preloaded hard drives and sell them to consumers. This is why a laptop is a bit more complicated to support with coreboot. The OEM's may not even have all the specifications for the laptop since the ODM has done all the design and assembly.

Some laptop ODMs are:

  • Quanta makes laptops for Sony, Dell, and IBM
  • Inventec and Arima make the Compaq line
  • Compal also makes IBM and Dell lines, as well as Hewlett Packard
  • Clevo makes the popular Alienware and Voodoo gaming laptops
