I need to add the /3GB attribute to my BOOT.INI file because a program I am using requires more than 2 GB of memory. However there is no /3GB box to check under msconfig so how do I add the attribute so I can expend the max memory allocations for programs? I cannot find my boot.ini file to edit manually. Itís not located under C:/. I am viewing hidden files and folders. I did a Windows search and the only thing I got back was "boot.ini.backup".

If you are trying to switch the virtual address space from 2GB to 3GB you need to use the BCDEdit /set command to set the iscreseuserva boot entry option from 2GB to 3GB.

The Microsoft Development Network web site has a full explanation.
