- I'm not a regular reader of this newsgroup, so if you post an answer,
- please email a copy to me.

- A dealer who recently upgraded a friend's motherboard told him that
- Win 3.1 has a bug preventing it from utilizing more than 12MB of RAM
- memory. This limitation applies to physical RAM, not virtual address
- space.
-
- This bothered me, since my machine has 16MB of RAM, and sometimes it
- pages more than I expect. The dealer said that Microsoft hasn't widely
- publicized the bug but can supply a patch for those requesting it.
-
- 1) Is this true? I'd never heard of this alleged bug before.
- 2) If so, how can I get the patch? I'd prefer floppies from Microsoft
- rather than a bulletin board, if possible.
- 3) Have you made the patch? How did it work? Any problems?
- 4) Is there any way under Windows I can determine how much physical
- RAM it is utilizing?
- 5) Can I find out how much memory each process is using and how much
- it is paging, i.e., something akin to the Unix 'ps' (process status)
- command?
- 6) If I expand my machine beyond 16MB of RAM, can Windows use it? If
- so, can one large process occupy more than 16MB of RAM? The program I
- have in mind (ParcPlace Smalltalk) is compiled with a 32-bit DOS
- extender and uses a flat 32-bit address space.
