Sometime is difficult to configure the system.
32 bits, with all the application and specially the drivers working perfect ?
But the accessed memory limited at 2.97 giga ?
Or 64, with problems with the drivers ?
And of course, all the memory accessed ?
For example, I was extremely disappointed with a plotter driver not working on W7 64...They announce officially that no deriver in the future on the manufacture site. and others.....
I find a solution:
It is a small windows patch, allow on the 32 systems to acces all the memory ! Tested and work
