XP pro 3GB switch

[sean armenta]

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.

i want to implement the 3GB switch as i am running photoshop CS2 and the program can utilize 3GB of RAM.

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:

It would appear you just add the /3GB. You can use multiple switches in your boot statement.

Here's the correct link:

http://www.microsoft.com/whdc/system/platf...PAE/PAEmem.mspx

Your boot.ini should read:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /3GB

thank you -- and thanks for fixing that link as well :)

so just to make sure -- the end result will look like this:

[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/3GB

or do i need to put a space after "fastdetect" so it will read "/fastdetect /3GB"

thanks again...

just re-read your post and i see you put the example in for me :)

anyway -- would there be no conflict if i included both lines?

[Scarecrow Man]

You need a space between each swtich.

/noexecute=optin /fastdetect /3GB

You can have both lines, so that one will load the default and one will load the 3GB switch.

Your fully completed boot.ini with both options would look like this:

[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
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional - 3GB Switch" /noexecute=optin /fastdetect /3GB

They will both load the same OS, on the same disk, but the second will enable the 3GB switch.

Are there any disadvantages of always using the 3 GB switch? Will some apps crash or become unstable? Why not always have it enabled?
