Tip & How-To about Microsoft Windows XP Home Edition for PC
The DOS will always take a percentage of the physical RAM on the motherboard leaving the rest for the User. By default the Windows Operating System will use 50% of the physical RAM installed on the motherboard leaving the user the remaining 50% this can be changed using a switch in the boot.ini file
The /3GB was originally meant to be used in systems that have 3GB or more of RAM something that is no longer quite as rare as it used to be Windows XP SP3 will support upto 4GB although on a 32bit (x86) version of Windows will acually see 3.25gb that is the limitation.
However, even if you don't have 3 GB or more of memory, you can still use the /3GB switch. the switch can have any value between 2048 (2 GB) and 3072 (3 GB) megabytes. It needs to be expressed in decimal notation.
The /3GB switch applies to 32-bit systems only (x86).
