And target1 also has the proper devices under it. Well, I never saw anything like that in any documentation...I thought I RTFM!

UML Port
Hi I want to run some virtual machines on my alpha to play around with with different distributions, kernel and such stuff. But noone of the popular emulators does imho work on linux/alpha (no emulation of the i386 instruction set like booch does). So I asked on the uml-devel-list (user mode linux) how hard it is to port the uml patch to other plattforms than i386, because this approach seems to me to be the fastest (in terms of execution speed) and most generic one. The answers were spare, and I've extracted from the answers, that the most problems are the plattform specific ones :-| So the question: Is there a need for a Usermode Patch, are people out there, who has knowledge of the alpha plattform and the linux kernel and are willing to contribute?

Re: UML Port
Isn't UML supposed to be incorporated into the 2.6 kernel? Will this have any effect in the world of Alpha?

Quick Question: Is it possible to install SID on Alpha direct from CD?
Hi, Its a good while since I looked at Debian (and Im no *nix expert anyhow), but could someone clarify if its possible to fresh install SID on an Alpha direct from the SID CDs? Afaik, more recent versions of Debian dropped support for Boot Floppies... what replaces them on the Alpha platform? Whats the usual install of SID on Alpha go like? thanks. Matt
