- THis is normal, and Sys7 DOES recognize the 4 megs you have. It
- keeps a copy of ALL of memory on the hard drive and then moves
- chunks in as they are needed, using the 4megs to store as much as
- possible before having to go to the disk again. i.e, the more memory
- you have, the less you will have to go back to the HD for what are
- called "memory misses."

- Sorry I can't help you with the rest....
