Well it isn't just that you don't want to use it, it is that you want to eliminate,
and if not eliminate, reduce, the main memory it consumes. Perhaps I should
elaborate some more so we can tell if we're on the same page...
It's my understanding that the BIOS causes up to 8MB of main memory to
be preallocated for integrated graphics use. This is memory that the OS
doesn't see (causes a reduction in the total physical memory reported by
Windows). If there is no way to prevent the Dell BIOS from doing that,
there is up to 8MB that you will lose no matter what. However, the
remainder of the "up to 64MB used by integrated graphics" is supposed
to be allocated by the driver/OS. If you're using a PCI card, you want
to prevent that.
Now back to what you just said. I don't have a system with multiple
graphics adapters, let alone a PCI card equipped 2400. So I can't poke
around and try to figure this out, or I would. If you "just don't select it in
display settings as a monitor to use", are you simply telling Windows not
to extend the desktop to the integrated graphics adapter but actually
leaving the driver installed and allocating the memory we don't want?
