Additional Notes

This is the viaagp1.sys file for 2000 and XP. This is extracted orginally from the file from VIA, but it is hard to find, plus you got to get the whole zip and you don't even know what your are looking for. The 4in1 driver is already on driverguide, but this is th stand alone .sys with the .inf and .cat.

"It was only good for using during windows XP re-install, as the setup requested viaagp1.sys. I used this file, but then once XP was installed I installed the graphics drivers correctly and everything A OK."
