STEP 0: Preparation

Unless you know what you're doing, you should test your new UMDK cart using a recent x86 or x64 Linux installation, on "real" (as opposed to virtual, e.g on VMware or VirtualBox) x86 or x64 hardware. The software will build and function correctly on MacOSX or Windows, or even on a Raspberry Pi, but whilst we're getting everyone up and running it makes sense to minimize the number of configurations being used.

So, you will need:

• A PC with a spare USB port and an Internet connection
• A recent Linux installation, x86 or x64 (amd64)
• A digital multimeter, for verifying voltage levels
• Four jumpers, for selecting options on the boards
• A good solid block of time to run through the test and install process
• Patience!
