In the program's properties, hit the Memory tab. You'll notice the
   defaults for these settings is "Auto"; this means Win95 will allocate
   memory as needed for this program to run. This can cause a lot of
   extra disk swapping, so you should find out what the game needs (Check
   its manual) and set the EMS and XMS values to match.
   
   Example 1: TIE Fighter (TM) (Floppy version) by LucasArts: TIE
   requires 2048 KB of EMS memory (Expanded memory), so set the EMS value
   to 2048 KB, and set XMS to None.
   
   Example 2: The Seventh Guest (TM) by Virgin/Trilobyte: T7G needs 4096
   KB of XMS memory (Extended memory), so set its XMS setting to 4096 and
   its EMS setting to None.
   
   Example 3: DOOM (TM) by id Software: DOOM doesn't use EMS or XMS
   memory, so set both of these values to None. Leave the DPMI (DOS
   protected mode interface) memory on Auto.
   
   Notice that all games use one kind of extra memory or another, but not
   two at once. You can always set one and turn the other off. This will
   ease Win95's job of guessing what the game needs. Of course, if a game
   runs completely in conventional memory, turn off everything BUT
   conventional memory.
   
   Oh yeah, that "Protected" switch is in here; turn it on if you think
   this program causes Win95 to crash. That switch can make LINKS 386
   operate in a DOS session where it otherwise wouldn't, for example.
