In my searches for an answer I turned up this old post

http://sourceforge.net/mailarchive/message.php?msg_id=9719541 

It refers to a magical ftp site that no longer seems to have the 
advertised content. The poster was not the creator of the content and the 
email address protection prevents me from asking the poster if he still 
has the content. So does anyone have a copy of the howto docs and custom 
source that used to live at

ftp://ftp.bpa.gov/downloads/software/openMosix/
