Tux with Warning.png
These kernels are INTENDED FOR ALPHA TESTING ONLY.

If you are looking for information on alternate stable kernels,

Application:UberKernel


PsychoKernel is the name of a series of experimental kernels, currently including F4, F102B, F104A, F105, AV8B, F14, F15C, and SR71. Yes, they are all Cold War era warbirds.

This experimental series of kernels is where new features are alpha tested before being incorporated into the mainstream stable Application:UberKernel release.

There is a continuous cycle of adding new features to PsychoKernels, then moving them to alpha testing versions of UberKernel, and then finally moving them to the public releases of UberKernel.

You should read the Application:UberKernel documentation first, as most of the features for the PsychoKernel series and UberKernel are identical.

All of these kernels are available from Preware, and you must use Preware to install or uninstall them. For the experimental alpha testing kernels, you will also need to manually add the alpha testing kernel feed to Preware to access them. If you cannot use your search skills to find the URL for that feed, then you probably wont make a good alpha tester ...

Discussion threads: SR71/F105 F102/F104 F15C (deleted due to people not reading the instructions) F4 AV8B F14
