"Looking for a low-cost way to get started with
embedded Linux? Or a fun weekend project? In this detailed how-to
article, Bill Gatliff explains everything you need to do to install
Linux on a Sega Dreamscast gaming console. Even the necessary Linux
kernel, bootloader, and utility kernel patches are included and
available for download. One of the more challenging aspects of
learning about embedded Linux is the scarcity of cheap, compatible
hardware. Sure, Linux runs fine on a personal computer, but does
being able to run Linux on your workstation mean you can call
yourself an embedded Linux guru?
Hardly. You may not believe me now, but you will shortly.
What's needed to really explore Linux as an embedded operating
system is a well-documented, inexpensive and readily available
hardware platform that isn't based on an Intel x86-compatible
microprocessor. By excluding PCs, the list of candidates becomes:
PDAs, internet appliances, and gaming consoles."
