XPS Gen4 BIOS support for >4GB memory remapping?

My situation is the same but I have a different setup. I have an XPS 410 with Windows Vista 32 bit. I have an Intel Quad 6600 processor, Sound Blaster Xtreme Gamer Fatality sound card (installed after), 850 GB harddrive (500GB installed later), and the Nvidia 750MB 8800 GTX (installed later). I would like for my system to read all 4GB but without the "memory remap" feature in the BIOS it does not let me do so.

I have read in many forums that even people with the 32 bit operating system can do a memory remap. I also understand the situation where the operating system reserves a portion of the memory for other tasks, however, with my new graphics card and sound card I would like to remap my memory so that it can read all 4GB. Also, despite the consideration that the operating system might be sectioning off my 4th GB to run vista applications needing more of a graphics card and such, I have a utility that is showing Vista using 1.5 GB of the 3GB that it is currently reading. I doubt that this means that Vista is using 2.5GB of my 4GB. (1.5GB + 1GB reserved) I would like to have this feature in my BIOS so that I can do this for I spent an extra $270 to get 4GB. I was hoping it was in the lastest BIOS update for the system, but it was not.

Count me in on this thread. The microsoft article lists the requirements for memory remapping:

The XPS410 seems to meet all requirements except the BIOS option. Is this planned for a future BIOS upgrade or are we forever limited to 3GB?
