UMSDOS is the msdos (FAT16) filesystem expanded for Linux support. The instructions are for using the Windows swap file in the windows folder. I'm suggesting that you create a FAT filesystem, tell Windows to create a permanent swapfile on it, then let Linux use that file too. You 'format' the file for swap & use it, and you need a script to do this automatically. The same commands used in Slack should work in RH, it's where you put them that's different. Take a look at the previously mentioned howto ( http://www.tldp.org/HOWTO/Swap-Space-6.html#ss6.4
) for info on how to get RH to do the needed stuff on startup.
