I have had no luck getting ATITool Beta .24x (any .24 Beta) to work with Windows XP 64-bit Beta 2, build 3790. It says everytime that "a kernel driver must be running". AMD 64 3400, Asus A8v Deluxe mb, Sapphire 800 Pro Vivo w/ 16 pipes (ATITOOL 0.23 worked fine before I upgraded to Windows XP Beta 2; I didn't test ATITOOL Beta .42 on the earlier Windows version).
Although ATITOOL 0.23 does work with Beta 2, it immediately distorts the monitor scan to the point that I have to manually re-adjust the monitor. It shifts the raster severely to the left, and greatly reduces both the vertical and horizontal scan sizes. As soon as ATITOOL is removed the scan returns to normal.
Has anyone attempted to use ATITOOL with Windows XP 64-bit Beta 2 (Service Pack 1, v.1433)? I have used both the MS-certified drivers and the latest from ATI.
