I would have started with that. It's actually the most deterministic as you are in full control. Yes the learning curve would have taken more time, but you spent a lot of time anyway... ;) > So spent 30 minutes digging out the manual from the moving boxes and > started reading through and happened to notice "AGP aperture size" in > the bios.

Right, but if you add or remove a card from your system (or enable disbale other devices in your BIOS) your problem has a good chance of returning. The AGP aperature size is the window size set on the CPU-PCI host bridge into main memory. It is not the size of the window set on the PCI-AGP bridge. However, since that PCI-AGP bridge window was misaligned by 128M, by bumping up some other window by 128M, you pushed the alignement of all the other windows that get set after it by 128M. So again, I'm glad it worked, but realize if you change hardware configuration, thus changing device memory windows, the problem will likely resurface. Now would be a good time to learn how to use setpci and write down some notes. :) > Again, Andy, I can't tell you how much I appreciate you spending the > time on such minute details. I really do appreciate it. You're welcome. I didn't spend a lot of time. I was mosty taking kids to birthday parties and horseback riding lessons yesterday. Ah the days when they take naps are gone for me...
