Alot of my favorite games are for Dos, but apparently windows XP, by default, lacks the extended memory support to play them, does anyone know a way to change this? :)

Located in the WINDOWS XP HELP MANUAL:

"Debug: xa (allocate expanded memory)Allocates a specified number of pages of expanded memory. Used without parameters, xa checks for the presence or absence of extended memory support (EMS).

Syntax
xa[count]

Parameters
count
Specifies the number of 16-kilobyte pages of expanded memory to allocate.
?
Displays a list of debug subcommands.
Remarks
Windows XP does not use this command. It is accepted only for compatibility with MS-DOS files.
Windows XP does not support EMS. To use expanded memory, you must install an expanded memory device driver that conforms to version 4.0 of the Lotus/Intel/Microsoft Expanded Memory Specification (LIM EMS).
If the specified number of pages is available, Debug.exe displays a message indicating the hexadecimal number of the handle that is created. Otherwise, Debug.exe displays an error message.
Examples
To allocate eight pages of expanded memory, type:

xa8

If the command is successful, Debug.exe displays a message similar to the following:

Handle created=0003"

It would appear you can't use them without the installation of a driver.

If you have older games that only run in DOS you might want to look into something like DOSBox (http://dosbox.sourceforge.net/news.php?show_news=1), which will allow you to run the games in a DOS emulator.
