How do I speed up my application?
If the application you are using runs really slow, close
any other applications you are not using - this should speed things up.
If this doesn't help, save your work, close the application, and exit
Windows. Restart Windows and the application you want to run.
If your application still runs slow, you might consider installing
additional memory (see "Memory Module Installation" in Chapter 4).
Also, refer to your operating system's documentation for tips on
optimizing system performance.
Why do I get a message "Insufficient memory"
when I run some games? I have 32 MB of memory.
The "Insufficient memory" refers to the 640 kilobytes
of base memory. Since there are drivers being loaded at power on, the
amount of memory can be lower than the game requires.
Contact the game manufacturer and request advice to create a boot disk.
This will load only the drivers necessary to run the game.
