Re: EMC and new Redhat.

Hi Fred,

I've just been looking to download the RT-linux patch and I can't locate the
Beta16 version on the FSM Labs site. It looks like they are happy with it
and have renamed it RTlinux-2.0 but there appears to be 2 versions which has
confused me a little. There is a straight RTlinux-2.0.tgz at around 1/2MB
and an RTlinux-2.0-prepatched.tgz at around 15MB so I'm not sure which would
be best. Looking at the file sizes, I assume that the '-prepatched-' version
is a complete RTlinux kernel but would this work with EMC?
