If the entry is not present, follow this procedure to add the switch:

1. Locate the 'boot.ini' file, typically in the root folder (for example, C:) and remove its read-only attribute.

2. Open the 'boot.ini' file, and then add the /PAE parameter to the ARC path, as shown here: multi(0)disk(0)rdisk(0)partition(2)WINNT="Windows 2000 Advanced Server" /PAE

3. On the File menu, click Save.
   
4. Restore the read-only attribute to the 'boot.ini' file.
   
5. Recycle the server to allow PAE to take effect.

Virtual memory mapped above 4 GB is available for data caching or paging and reduces the need for disk access by keeping the data in memory. Microsoft recommends enabling PAE for applications that move large amounts of data into memory such as SQL Server. Use of PAE is available on Intel Pentium Pro or greater systems running Windows operating systems capable of using greater than 4 GB of RAM such as Windows 2000 Advanced Server and Datacenter Server.
