                           XMSUMBInitCalls=<Boolean>
Default:        Usually true, but may be false depending on the extended
                memory manager you are using.
Purpose:        Specifies whether or not Windows should call the extended
                memory driver's upper memory block (UMB) management
                routines.
To Change:      Use Notepad to edit the SYSTEM.INI file. (You should never
                need to change this setting.) |
