Ready to fly: Chipflasher’s Flashrom Interface is Up and Running
I am very pleased to announce herewith the successful release of Chipflasher’s Flashrom Interface. The project’s core milestone #3(7) is now done. It links a widely used free software project to hardware of a free design, even down to chip level.
I receive great support from OSE-Germany e.V. and associated fellows, as well as from Michiel Leenaars from the NLnet Foundation. I am very grateful to meet your friendly companionship and encouragement!
Now have fun to see the documentation: Chipflasher Flashrom Interface

More Laptops in Shop
Occasionally, ThinkPads come with flash chips that have volatile
registers. The chipflasher now handles these types more reliably with
kick2, the second firmware approach. Selected devices move into the
shop:
- Zerocat X220 Guix Machine + SPM – faeroese
- Zerocat T60 Guix Machine + SPM – german
- Zerocat T60 Guix Machine + SPM + 1TB – german
At power-up, volatile registers are set into Software Protection Mode (SPM) by the flash itself, that is why Hardware Protection Mode (HPM) cannot be applied via jumper.

New Projects
Zerocat Hyperbola Setup – Get the Hyperbola Operating System installed.
The Hyperbola Wiki provides detailed information on how to set up the Hyperbola Operating System, manually. Zerocat wraps selected steps into a script, such that the installation is automated and easier to accomplish.
Zerocat Parabola Setup – Get the Parabola Operating System installed.
This project offers a drop-in replacement for the original Install CLI of the parabola-dual-openrc-lxde-2020.08.03-netinstall.iso, which can be downloaded from the Parabola Wiki.
Zerocat Sleeve – Create a nice sleeve for your laptop.
A small, ancillary project for the creation of nice sleeves with a cat logo.

New Logotypes and Icons
Zerocat used to use the last letter of the latin alphabet for its icons, in conjunction with an emphasized exclamation mark. However, we have to face the fact that this letter has been hijacked. As a consequence, we now drop that letter and use different icons as a clear act of sympathy and empowerment for the ukrainian people and for peace.

New Chipflasher PCB
The chipflasher project comes with an updated printed circuit board (PCB). Version board-v1.3.0 brings new features:
- Board version stamp
- Onboard cooling areas for voltage regulators U5 and U7
- Additional, fast SPI bus power capacitor C11 footprint
- Refined routes and power tracks
- Better cooling for MOSFET Q1
- Space for angular, 90° SPI bus connector
- Auxiliary connector with 12 GPIOs and power pins on solder side
The CAD files have not yet been used for production – a budget of €500,- is needed to place the order of PCBs and to start assemblage. Please help!

Website Clean-up
- Dropdown All Projects provides instant access to all projects’ master documentations. Page Core Projects becomes redundant and is deleted.
- Project Turning Hook turns into a private repository.
- Page Power Station is removed.
This clean-up eases orientation and helps focussing on core activities.

It’s always satisfying to modify and free yet another Thinkpad: digging deeper, finding tweaks, making firmware replacement even simpler. My T430 has been flashed without even touching the fan! Let’s elaborate clipless procedures for more models, come and join the Zerocat Flash Access project!

New Project
Zerocat Flash Access – Interfacing BIOS Chips in Hardware Protection Mode
This project demonstrates how your Free-Software Laptop security is further enhanced by activating the Hardware Protection Mode (HPM) of its BIOS chips. This feature is of special significance because it guarantees that your machine will always boot with the same code.

Hurray, the year is over!
It was a difficult year for me and many others, so we do not need to make a resumé! Let’s focus on the next steps instead – I can’t wait to make them all come true in 2022:
- Zerocat Chipflasher Flashrom Interface made great progress and continues to receive funding from the NLnet foundation! The project is now starting with core milestone #3(10).
- Boost production of the latest free software laptops. In 2022 we will continue to provide the best quality laptops and promote their use. Current trends in digital surveillance, social control and pressure, makes this more relevant than ever. We are all in urgent need of private, secure communication equipment and all-purpose computers.
- Launch of Zerocat’s crowd funding page. As we move into many new projects, we need funds to scale up!
I wish you all the very best for the new year and invite you to stop using compromised hardware and smartphones, throw them away! The sooner we liberate ourselves from that crap, the better we can save families, neighboorhoods and societies.

Zerocat Chipflasher v0.6.1 released!
This is a major step! The interface to the project’s
connectutility has greatly been improved. You have full access to chips’ configuration registers and their protection and lock bits.As an exciting, special feature, it also lets you access and lock the Secured One-Time-Programmable Regions, often found on ThinkPads. Lock the regions, before someone else will do it!
Furthermore, end-of-write-cycle detection can be switched from polling to timeout – This eases flashing of ThinkPad models T530 and W530.
Please note that Zerocat Coreboot Machines has been advanced, too. It now ships version v0.16.2.
Last but not least, all project documentations support inline images – I very much hope you like that!

Free designs become even more important these times, ...
... as we see that societies rely on solidarité rather than on commercial market in cases of emergency. The right way to go is to request free designs not only for software, hardware and seeds, but for immunology vaccine as well.
