This article is from the comp.sys.acorn FAQ, by Paul Vigay with numerous contributions by others.
Due to the rapid development of Linux exact details about the latest incarnation of Linux are not kept in this FAQ. However for the latest information you might like to consult these web pages, or email the people involved with the port :-
Native Linux page :- http://www.arm.uk.linux.org/ (firstname.lastname@example.org)
The Iyonix machine has a near complete Linux port available for me. Further information can be found at http://www.iyonix.com/linux.html
Peter Naulls has some very useful ARM Linux resources available on his website at http://www.chocky.org/linux/
Additional information can be obtained from Aleph 1, who are now developing a complete ARMLinux distribution. Further information can be obtained from http://www.aleph1.co.uk
If you have the original Acorn Clan disc and would like to install ARMLinux, I have written a Dummies Guide to Installing ARMLinux which is available at http://www.vigay.com/riscos/armlinux.html. However, I no longer run ARMLinux personally, so this page is no longer maintained.
