Product Information ZC-X60 with Zerocat Toolchain

Dear Customer,

thank you for having purchased a ZC-X60 Free Software Laptop!

This Machine is a very special device, for it runs with free BIOS software right from power-up, no proprietary binary blobs included!

However, no system is perfect, so isn't this one. Please get familiar with your computer carefully. Please avoid modifications of your system settings without having accumulated some basic background knowledge in advance.

Zerocat Toolchain

This Laptop is ready to drive the RYF-Certified Zerocat Chipflasher, your Free-Design Tool to write free firmware to BIOS chips of selected motherboards. All related free software projects are located on the Desktop. You might want to see ~/Desktop/zerocat/projects/coreboot-machines/doc/ to get started.

Scope of Delivery

  • Laptop including Main Battery (Capacity >= 70%)
  • Docking Station with RS232 port, DVD-Multi III Recorder

If you need to see how your ROM image has been created, these are your options:

  • See Zerocat’s Coreboot Machines
  • Clone the documentation via git clone git:// and read the doc/ textfile.
  • See your local folder: ~/Desktop/zerocat/projects/coreboot-machines/doc/

Boot Options

When your system boots, a first GRUB menu will pop up for two seconds. Hit any key in order to access the menu, otherwise the start of your operating system will be selected automatically.


  • In order to start a Trisquel-USB-Live-Image, select "[u] Search ISOLINUX Menu (USB)".
  • In order to start a recent Debian-USB-Drive, select "[s] Search GRUB2 Configuration (USB)".
  • In order to cycle through pre-flashed background images, select "[i] Cycle through Background Images". Typical images are Zerocat’s logo or a photo of the flash procedure itself. A simple black background is included as well, which might be useful if you want to enter the GRUB Console.

Experimental Payloads

Secondary Payloads like NVRAMCUI and Coreinfo freeze from time to time, please use with care. Selecting these Payloads right after cold start seems to work most reliable.
