Just one note on this -- it is possible to fill all of your slots with a 3940. The cards downwind of it just have to be able to share interrupts. I've got an ASUS P/I-P65UP5 w/ C-P6ND cpu card, and the following card/slot configuration: slot 1: SMC 10/100 ethernet card slot 2: Hauppauge WinCast/TV dbx slot 3: SMC 10/100 ethernet card slot 4: Adaptec 3940UW slot 5: Matrox Millennium The Adaptec board shares two interrupts -- one with the Matrox card and one with SMC card in slot 1. -- Kenneth Merry ken@ulc199.residence.gatech.edu Disclaimer: I don't speak for GTRI, GT, or Elvis.
