After installation, my ethernet, CDROM drive, and/or other hardware that I thought Linux supported doesn work. Why?
Probably because the kernel you’re running doesn’t contain the support. To fix the problem, you’ll have to install a kernel that does. There might a suitable kernel in the /kernels directory on the CDROM, or you can compile a custom kernel for your machine. This isn’t too difficult — see the instructions below about compiling a new kernel. You can also try loading the device driver in the form of a kernel module. There are drivers for nearly all the hardware supported by Linux in the /modules directory on the CDROM, or in your /lib/modules directory if you’ve installed the modules.tgz package. Take a look at your /etc/rc.d/rc.modules file for examples of how to load these.
