Chipflasher’s Road towards RYF...

Dear Folks! Zerocat’s Chipflasher has been certified! First ten devices – tagged with the Free Software Foundation’s “Respects-Your-Freedom” (RYF) Certificate – are now available as a Limited Edition. Read the Full Story. See our Shop and help to further fund the project with your purchase!

Zerocat’s Coreboot Machines

Note the following machines of course aren't true free-design devices! Instead, these are refurbished and modified machines that carry a decent Coreboot 4.7 Firmware and as few proprietary code as possible in their BIOS chips. Regarding Intel’s integrated proprietary Manageability Engine (IME) which pops up severe privacy issues, mind these important categories:

Please read The Intel Management Engine: an attack on computer users' freedom by Denis GNUtoo Carikli and Molly de Blanc in order to get precise details.

ZC-X200

This machine is very common when it comes to delete proprietary blobs in the BIOS chip. It runs blobfree, however the Intel Manageability Engine (IME) architecture still is functioning and we don't know exactly about its hardcoded capabilities.

ZC-X200 | Dual Core | 8GB RAM | 8MB Flash, IME Firmware deleted

ZC-X200 | Dual Core | 8GB RAM | 8MB Flash, IME Firmware deleted

ZC-T400

Same as ZC-X200, but socketed CPU, integrated disk slot, touch-pad, more ports, stereo speakers, etc...

ZC-T400 | Dual Core in Socket | 8GB RAM | 8MB Flash, IME Firmware deleted

ZC-T400 | Dual Core in Socket | 8GB RAM | 8MB Flash, IME Firmware deleted

ZC-T60

This is an old laptop that still is very interesting for it offers modern 64bit support while lacking the annoying IME architecture:

[...] many Intel computers manufactured in 2006 have the ancestor of the Management Engine which is disabled from the start, such as the Lenovo Thinkpads X60, X60s, X60 Tablet and T60, and many more. --- Denis GNUtoo Carikli Contributions

If you have a strong stance on trust rather than performance, use this machine.

ZC-T60 | Dual Core in Socket | 3GB RAM | 2MB Flash | Free of IME!

ZC-T60 | Dual Core in Socket | 3GB RAM | 2MB Flash | Free of IME!

ZC-X230

Very performant laptop with dual or quad core CPU; IME firmware is not yet deleted but stripped down with ME_Cleaner. Note the heads project may run on this type of machine to gain improved security, but we haven't tried it, yet.

ZC-X230 | Dual/Quad Core | 16GB RAM | 12MB Flash, IME Firmware stripped down

Zerocat’s Coreboot Configuration has been adjusted to provide the GRUB2.02 Bootloader with full authentication support, chainloading SeaBIOS rel-1.11.2 as a secondary payload to allow for booting the Qubes R4.0 OS Installer from CD or USB-Stick.

Laptops gain New Qualities

In short summary, these machines gain ethical qualities, as they...

...are accompanied with free documentation, you can create them on your own!

Our notes on how we configure and tweak the coreboot BIOS images are publically available. You may review or reproduce our approach and get convinced about its integrity.

Since we are developing a true free-design chipflasher, we continue to flash these machines for testing purposes and offer our flash services as well as ready made laptops for purchase. If no related sales page is available in our shop, please feel free to request one.
