- Os/2 can currently use up to 512MB, a limit wich is supposed to be lifted
- to 4GB when the last 16-bit parts of it is rewritten to 32-bit.
- However, os/2 won't load programs over the 16MB line if the dma-controller
- controlling your swap disk cannot reach beyond 16MB. This is the case
- for ISA-controllers. EISA, MCA and some local-bus controllers can use >16MB.
- You may also choose to not swap if you go for 20MB.

- No problem. Os/2 use virtual memory, and can swap out a lot of things, including
- much of itself. A program requiring only 2MB EMS+640kB should run fine.

- I use 8MB and is satisfied with that, althoug 16 is better. IBM claims that
- the next version will run fine in only 4MB...
