I've tested Geforce 6600GT 128MB , 7600GT 256MB and 8600GT 256MB (all PCI-E) on another Board MSI 7058 915P Combo FR (chipset Intel i915P) with AMI BIOS. Previously I had tested on a similar Board MSI 7140 Combo 2 (i915G), but it has an Award BIOS. OS: Win ME Result: -6600GT 128MB works with Nvidia drivers - To shutdown I use the bootmanager PLoP or I can install the older Nvidia driver 77.72. -7600GT 256MB doesn't work with Nvidia drivers (but I'll try it again) After driver setup and reboot the maschine switched off. But it has worked with the bearwindows driver (of course the refresh rate is a little bad - CRT Display). - 8600GT 256MB doesn't work with Nvidia drivers. After the Setup and the following reboot the machine hangs respectively crashed with a blue-grey checked colored screen and a few letters. It's surprising to me that the Bearwindows driver works. Note: The Chipset Driver is Intel 6.3.0.1007. Two exclamation-marks remain in the device manager at motherboard-ressources (Code 15), but it seems to be no problem. The machine works stable. Of course there is no driver for onboard USB 2.0 and onboard sound.
