Revision as of 18:35, 4 June 2010

Recent progress of coreboot on laptops

  • coreboot supports the Getac P470 semi rugged notebook, based on Intel 82945GM/ICH7.
  • coreboot supports the Roda RK886EX (Rocky III+) laptop, based on Intel 82945GM/ICH7.
  • VIA has recently released open documentation for the VX700 and VX800 chipsets at the VIA Download Portal.

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 a superiotool (latest svn) and build it
  • run as root 'superiotool -deV' and save output
  • download a ectool (latest svn) and build it
  • run as root 'ectool' and save output
  • 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

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

Random product links

VIA has a list of many netbooks at VIA Partner Mobility Devices.

VIA also has information on other mobile platforms at VIA Mobility Platform.

The Quanta IL1 vx800 based reference design covers similar models/clones such as:

Other vx800 based netbooks:

There are still a few netbook designs currently on the market that use the VIA vx700 chipset:

There are also several AMD 690/600 laptops still available that may be candidates as well:
