The third hurdle that you face when you begin to set up the EMC is getting and installing the EMC software itself. Much of the EMC and RCSLIB have been placed on SourceForge.net in a concurrent versioning repository and are available for download from that site. Along with that change there has been a change in the nature of the distributions.
Installation can be a daunting task to people new to Linux. The hardest part is getting the Real Time Linux patch up and running. After that, installing EMC is pretty easy. With that said, most people have found that the easiest way to install Real Time Linux and EMC is to go to Tim Goldstein's web page and use his install script for EMC on the linux 2.0.36 release. The information on this is under the download information link above.
Ray Henry has written a page on installation of EMC on his computer running Mandrake 7.0 with a prepatched rtlinux-2.2 kernel. Ray doesn't have an install script but the process is documented fairly well and he has some text files that you can view or download.
Brian Pitt has written a guide to installing Linux, Real-Time Linux, and EMC on a windows formatted hard drive using a Slackware installation. This looks like a reasonably easy way to try out the system. Look for installation CDROM's soon.
