This document is not a guide to installing Debian. You'll want to look at the Potato install guide for instructions on installing Debian 2.2. Not everybody gets it to work on the first try. Try booting with a different kernel, from the list above. Try a different Penguin booter.
Some ethernet cards refuse to work unless the network is physically unplugged before booting.
Also, try booting with extensions off to remove any software conflicts. See the FAQ for details. The trick is to get your machine down to the absolute basics, and then Linux should work for you. Then gradually add your hardware and software until you find the problem. If you continue to have problems, you can always search the mailing list archives to see if anyone has had the same problem as you.
