I hate to contribute in a negative fashion, but there is apparantly still a
great deal of misinformation about the AGP aperture setting.
It is not a mechanism to *force* or even *allocate* system memory to be used
by a video card.
In fact, the AGP aperture size setting only adjusts the size of the memory
space assigned to the index table we call GART. (Which maps messy video card
memory into a nice, clean block for the application to use efficiently.)
Modern cards do not need the user to waste OS memory space by allocating
more than is required for their 128M or 256M card, which is a setting of 64.
Beware, setting below 16 forces AGP1x mode in certain BIOSes.
The OP will not be helped by this info regrettably.
