| − | '''PRE BUILD ENVIRONMENT IS ASSUMED ALREADY INSTALLED ON THE SYSTEM YOU'RE BUILDING'''
| + | Moved to the official docs, see here: https://docs.fogproject.org/en/latest/reference/compile_fos_kernel.html |
| − | NOTE: It is assumed you have root access to the system you're building this on. It also assumes you know your CWD (Current Working Directory).

| − | = Build TomElliott Kernel for FOG 0.32 and earlier=
| |
| − | The below instructions are to build the TomElliott kernel. There is an extra step involved compared to the normal kernel build as there are firmware's built directly into the kernels now.
| |
| − | == Download the Kernel ==
| |
| − | As of the time of this writing kernel 3.13 is the latest. You can use previous, or future kernels as well though.
