Hi,
I have a few questions that may have been discussed before. I have 2.6 MB
memory on my 286 Compaq which supports LIM 3.2. I am also using Compaq
Dos 3.31.
o Which type of memory should I configure for best performance ?
(Exp vs. Ext) ? I can have both of them.
o In running WIndows 286, how do I make use of the extra memory
to open more applications instead of converting all to cache
memory (using Smartdrive.sys). I read from the documentation
that it supports only LIM 4.0 ?
o Will my above configuration be sufficient to run OS/2 with
presentation manager ? What about Unix ?
I would appreciate any pointers or suggestions. Thanks !!
Andy

To swap processes in Windows you should use expanded memory. Extended just buys you 64K (Windows uses it for something that I havn't figured out yet). > o In running WIndows 286, how do I make use of the extra memory > to open more applications instead of converting all to cache > memory (using Smartdrive.sys). I read from the documentation > that it supports only LIM 4.0 ? This is where life gets tricky. You basically need large frame EMS to do this. So, depending on what kind of memory you have in your system, you may or may not be able to do this. You didn't mention what kind of memory card you have in your system, so I have no clue if it's large frame or not. However, I can tell you that the AST Rampage and the Intel Above Board + are large frame EMS. Then comes backfilling. To get the best results for process swapping you should backfill your computer from 256K on. This basically means that you tell your computer that you have 256K on the motherboard (this needs to be set via hardware switches) and then tell the expanded memory board to start at 256K on the motherboard. > o Will my above configuration be sufficient to run OS/2 with > presentation manager ? What about Unix ? The configuration that works best for Windows won't work for OS/2. In their infinitly grand way of doing things, Windows uses expanded memory, OS2 uses extended memory. I'm not sure why Microsoft (or IBM?) did this, but that's how it is. I believe that Unix uses extended memory also. -- "I place my faith in fools.
