3GB switch and SP1 Hotfix

Message stated about the hot fix (q328269_WXP_SP2_x86_ENU.exe). I am not able to fin this anywhere on microsoft web site. Can anyone help.
This is suppose to be applied if you are running SP1 before the 3GB switch is put in to place. Below is where I got thins info from


***WARNING***
Problems caused by improperly editing the BOOT.INI may prevent your system from booting correctly and could render your computer operating system unusable. Microsoft has provided a wealth of critical information you need to know about the BOOT.INI file in the Microsoft Knowledge Base at http://support.Microsoft.com/support.
Edit the BOOT.INI file only at your own risk and only after backing up the original.

Example BOOT.INI file:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /3GB /fastdetect

You should ensure that you have a total of at least 3GB set aside for the Paging File Size to fully utilize the available address space. Also note that every concurrently running application is sharing the available paging file size, so setting to something more than 3 GB (such as 4 GB) is recommended. In order to check the amount of memory you currently have allocated follow these steps:
1) Press the Windows+Pause|Break keys simultaneously to gain access to the System Properties
2) Click the Advanced tab, then, Settings button in the Performance group.
3) In the Performance Options dialog box click the Advanced tab and look at the section titled Virtual Memory. The total amount of memory currently allocated will be displayed here in megabytes

To ensure that Inventor is actually allocating memory in the 3 GB range, start Inventor and then choose Help>About Autodesk Inventor. The first line of text under the splash screen image should say: Autodesk Inventor %release% - 3GB. If the - 3GB is shown, Inventor is successfully using the feature; otherwise, it is not. (Releases prior to Inventor 6 SP2 have not been enabled. Of course, the release number may vary.)

Limitations:
Executable files must be specially built to enable the larger address space. The only Autodesk executable file shipped in the Autodesk Inventor Series to be enabled to leverage the 3GB switch is Inventor.exe. Other executables shipped with Autodesk Inventor have not been enabled. Most likely, the applications provided by other software vendors have also not been enabled to use this feature.
The feature only works on Windows XP. Furthermore, the Windows XP SP1 service pack had disabled it. To re-enable it for Windows XP SP1, there is a hotfix from Microsoft that must be applied. (q328269_WXP_SP2_x86_ENU.exe). This seem to be fine in SP2.

It is not possible to enable the feature on Windows NT, Windows 2000, or Windows 9x.

Be aware that the OS now has less memory space. It is not completely clear what implications that may have on Windows XP, but it would be wise to be somewhat cautious with regard to the total application load placed on Windows while running in this mode. If you don’t specifically need the larger address space, it is recommended that you do not enable this option.
Only marginal performance improvement could occur on systems using swap space on the systems hard disk to increase the available virtual memory rather than using physical memory (1 gigabyte of physical memory and a 3 gigabytes swap file). A significant amount of time reading and writing occurs when the system hard disk is used reducing the benefit of this feature.

Always remember that the 3GB switch is a hack to the OS.
SP2 is really required. (The SP1 implementation had at least the problem
described below.)
Please read: http://www.inventor-certified.com/graphics/faq.php#3gb
This is derived from reading Microsoft material and my own testing.
The additional switch USRVA was added in SP 2. This lets on adjust the
dividing line for Virtual memory between 2 and 3 GB. You will have to
experiment to find out the correct value for the USRVA switch.
This is required for most systems as the OS often is running more services
than just a bare bones system.

Run only the minimum applications at the same time.
Do not install or uninstall software in this mode.
