Module Name:
|
|
|
|
shell.c
|
|
|
|
Abstract:
|
|
|
|
This module contains code to set the shell optimizations based on the system's physical memory
|
|
|
|
[ComputerSettings]
|
|
OptimizeShell = YES | NO - Overides the default optimization. The default is based on the amount of
|
|
physical memory on the system. If the system has less than MIN_MEMORY MB of memory
|
|
the default for this key will be NO, otherwise, it will be YES.
