I bought a DELL Precision 2 CPU 420 MT workstation for Video capturing. I want to use 4 Pinnacle miroVideo PCTV cards.
This Dell 420 machine has 5 PCI slots. I find PCI1,PCI2,and PCI3 works correctly with PCTV cards and VIC.
The problem is that when I put the card into PCI4 or PCI5, the command " modprobe bttv" is OK, but VIC doesn't capture image, it doesn't respond.
I tried Linux kernel 2.2.16 and 2.2.14, neither works. But in Win98 and 2000, PCTV in PCI 4 and PCI 5 works good. and I also tried some other BT848 cards and find the same result.
I cannt find any difference between these PCI slots. Can you tell me why in Linux PCTV and VIC works good in PCI1-3 slots, but refuse to work in PCI4&5 slots? Shall I change bttv drivers in Linux?
Thanks in advance
