Hmmm. Installed them and they work fine. Cleaned up my display Control Panel also. They're "6351s" (v.6.14.10.6351). I believe 6343 is Cat3.4, 6307 is Cat3.2, and 6292 is Cat3.1. (I think ATI skipped Cat3.3.) My previous Cat3.5's from s-seven.net or elsewhere were 6360s. Regardless, "approved" and updated ATI M9 drivers from Sager! (Thanks guys!) As per usual, I uninstalled my ATI Control Panel and ATI Drivers via Control Panel and Add\Remove Programs. I rebooted, ignored the driver install messages from XP, and installed the Sagers. (Extract the Sagers by double-clicking the ATI7_89.exe you've downloaded, then find the folder and double-click the setup.exe in the "root" folder, of course. The setup installs both the drivers and the ATI Control Panel.) Happy driving!
