I recalled that I have a Linux kit for PS2.
I wonder if I can somehow place Gentoo on it.
The only problem or inconvience I found was that PS2 Linux required to boot from CD and then load some settings from Memory Card.

yeah it's been like that since....man a long time ago. maybe if we flood him with email he might start up again. but i know for a fact that you can get gentoo(x) on the xbox.

I actually gave some help to the guy who worked on this port. But someone wound up leaking the information to Slashdot, and the guy suddenly disappeared. The port is open to anyone willing to dedicate the time to finishing it (which, mind you, will not be an easy task).

Any attempts made on the finishing the PS2 Port will not be easy undertakings. Keep this in mind. First, you'll need a rather deep understanding of the portage system, mainly in how profiles work, the stage building process, and how catalyst is used to build install stages (there are docs available on this on the Gentoo site). An understanding of a compiler toolchain also helps, as any PS2 Linux port will not be able to make use of the default gcc versions available. At the least, any PS2 port will most likely be using an outdated gcc and binutils version, compared with the available version to normal gentoo systems. Because of this, a PS2 port will need to be locked down to these specific toolchain versions to avoid issues.

Other things are a small understanding of the MIPS architecture, at least as far as what it is, the various ABI's (o32, n32, n64), ISA's (MIPS-I,-II,-III,-IV), and CPUs commonly found (R4x00, R5000, R10000, etc..). These don't really help on PS2 itself, but being aware of them, and understanding what they are helps one to understand why the MIPS architecture has been a favourite among game console developers (i.e., PSX was an R3000 MIPS, N64 was an R4300, Most SGI systems are MIPS, etc...).

Lastly, no leaking to slashdot :P This drove the last guy off I think, but I'm really not sure. After the work got posted on slashdot, I do know the server at his work that was hosting the stages felt the brunt of a slashdotting, but he disappeared off IRC shortly thereafter.

All in all, your greatest asset will be pure and simple luck.

that sound's cool and all, but i'll be honest, i've never "developed" anything. i want to, but i'm still learning networking with linux in general. assuming i did want to do something along these lines, what should i start reading? i bet it's safe to say i should learn C right?

Yes. And Assembly, too, or else you probably wont get that sexy GCC or libc working. 8O

Quite honestly, I think screwing around with MIPS assembly is way too much trouble. 8O Seeing as how you haven't learned any C yet, it'll be damn hard to learn something like Assembly, especially on a sort of non-standard architecture. Though I guess there is probably already a GCC for some form of MIPS and Linux can obviously be compiled under MIPS, but if the PS2 isn't a -standard- MIPS, then you'll have to port the entire Linux kernel, GCC, libc, Grub, ReiserFS/ext*, binutils, etc, etc...

Of course, most of that seems to be done already, so I'm probably wrong. I'm just saying IF. So take a look at that thing, and see if you can make anything out of it.

Well you don't have to entirely shoulder the responsibility. The PS2 linux kit community has done some pretty decent stuff with the limitations that Sony has given to them. You could technically stay with their kernel or used some of the patched ones on their forum. Untar a mips stage1 and try to bootstrap it and see what happens.

Is the R5900 backwards compatable with other Mips executables?
