I'm not really sure what you want to do. Comedi works just fine on your
standard, off-the-shelf, RedHat kernel (including RH7.3). You need RTLinux
(or RTAILinux) if you want to read values in, do some math, and then write
values out, faster than a couple hundred times a second, or with very
precise temporal behavior. 

If you want to update your outputs < 100 times a second, you don't really
need a real-time Linux. If you want to update your outputs > 1000 times a
second, you definately need a real-time linux. If it's between 100 & 1000,
you can do a bad job with a plain kernel, a great job with a real-time
kernel. Hope this helps :(

Well, good luck! I'll help you if I can. If you decide that you need a
real-time Linux (RTLinux or RTAILinux), it's not that difficult to set up.
You can start from your plain old RedHat 7.3, and in a couple of hours
(or a couple of days if you're unlucky) have a working real-time computer.
Just go to one of the websites, and follow the instructions. I'd be more
than happy to give advice along the way...
