Answer 1

okay, first off, for that VGA setting, you do not want to use any system memory for textures.  especially being that it is PCI textures.  you have an AGP card, PCI does not even apply for you.  even if your video card was 64mb or 128mb, you would not want to use any system memory.  let the card handle what its supposed to handle.  if you are primarily playing games and you're not editing intensive media, the card can hold its own just fine without using your precious system memory.  and trust me, your system memory, when doing ANYTHING at all, is precious.  the more system memory you can have dedicated to a certain thing at one time, the better that certain thing will run.  turn that setting all the way down to 0.  i have found that sometimes it will not accept a value of 0, so i just place it at 1.  keep it as low as possible, that system memory is important.
the BIOS aperture size should also be turned off.  i believe (don't quote me on this) that the aperture is referring to a PCI card.  which, as stated before, you do not have, you have an AGP card.  so turn this off, the system will recognize the card and all its available memory from the bios directly.  having an aperture is using that precious system memory i was talking about.
one benefit of AGP versus PCI cards is that an AGP is much more capable of using its own memory instead of having to steal memory from your system's ram.  of course, there are many more noteworthy benefits of AGP vs PCI, but for this question, the applicable answer is, turn that stuff off and down.

system memory for textures in PCI MODE
