Revision as of 12:17, 1 February 2010

Recent Progress of coreboot on Laptops

  • coreboot now 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). The most common EC's in these netbooks are the KB3310, KB3910 and KB3920 from ENE Technology. The ENE EC's are 8051 based and are used to support keyboard scan, lid open/closed, battery charging, power management, etc.

coreboot may work with the "stock" 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)?


The Quanta IL1 reference design seems to use ENE3310 controller. The q1d25i.rom was examined. The EC code is on 0xFFF00000 on One Mini A110. Its 64KB big HOLE0.ROM.

Example code that makes use of the KB3310's "Index IO" access functions.

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
