OK, I've read more carefully the link. This link is about making a "from scratch" install of Linux. This is probably not what you want, as it's much more work than just installing Gentoo.

However there's much more info in this link. It tells us, in particular, that if you use 2.6, you don't need any special patch to get your system running. (the "latest 2.5 PPC development patches" it mentions have now long been merged into 2.6 mainline). That means that 1) Gentoo will very probably work for you, and 2) if you don't want Gentoo, it must be quite easy to cross-compile a 2.6 kernel for you. The link I have given even explains how to cross-compile. Its explanation about how to get the latest kernel sources using BitKeeper is not interesting, just download standard tarballs on FTP,, and it will work. Then configure the kernel as they tell you. If you use 2.6, expect some options to be presented differently, but that's no big deal. Don't use a 2.4 config file with a 2.6 kernel. To get a good 2.6 .config file, follow a 2.6 HOWTO, and then apply the config hints given by the link I gave you. Then compile and install the new kernel. You don't have to care about the "root FS" if you already have a distribution installed.

Wow, thx again Ben. Looks like I'll have enough stuff to keep me busy this week. That link discusses the ML310 board, which is what I am using, and gives a concrete example for the ML300, which is similar enough to allow me to follow his steps. If nothing else, I guess I will learn a bit more about Linux!

I will update you later this week (or next weekend) to let you know where I am (and, more likely, where you can help some more!). I did some research myself and found out that the PPC405 doesn't offer any direct HW support for SMP (though fancier PPC versions do), so that might be a minor roadblock to Linux for SMP for right now, may have to focus more energy on the HW side (build some FPGA pieces?) for a little while to work out those issues.

Thanks again...

OK, good luck. I don't know exactly l what a FPGA is, but that sure looks like a great thing to play with...
