Chris,

   Thanks for the help. I've been reading about thses instructions
and have have tried (they work!). But, do you have any idea how
it works? By simply using /dev/ram1 does the kernel know to use
memory? Is this memory dynamic in that I can make the filesystem
to be any size I want and the kernel assigns that much memory to it?

Thanks!

Jeff
