Welcome to CRUX! It rocks :)

The latest (2.6) CRUX installation CD's Kernel will not work
out of the box (anymore?). It will not have the file system
(likely) that you've probably formatted your disk with.

You must compile the kernel yourself.

Once you've partitioned your disk, formatted it and run setup
chroot into your new system (using setup-chroot helper script)
and perform the following:

$ cd /usr/src/
$ ln -s linux-x.y.z linux # I like doing this
$ cd linux
$ make menuconfig # See notes below
$ make all
$ make modules_install
$ make install

Notes:

When "configuring your Kernel", be sure to (at the very least):

1. Select your Processor Type.
2. Select your File System Type.

Ensure that the above are "compiled-in" and NOT "modules".
