3GB switch

[seanarmenta]

was wondering if someone here could walk me through editing my boot.ini file to utilize the 3GB switch as explained here:

Are you using some apps that fall into this catagory ->

"The /3GB switch allocates 3 GB of virtual address space to an application that uses IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header. This switch allows applications to address 1 GB of additional virtual address space above 2 GB."

Couple ways to edit the boot.ini file.
One is Control Panel->System icon->Advanced tab->Startup and Recovery->Edit button.

okay... i tried it, but i don't think it quite worked. or maybe i did it wrong.

here's my default boot.ini:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

and here is the sample boot.ini change from the microsoft website of what i'm supposed to do:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="????" /3GB

Note: "????" in the previous example can be the programmatic name of any of the following operating system versions

so -- do i just add the "/3GB" to the very end of my boot.ini, or do i replace "/noexecute=optin /fastdetect" with "/3GB" ?

here's the entire article from microsoft:

i have installed 4GB of RAM, and i'm running a pentium D on windows xp pro, on an intel board with a 945G chipset.
