Hello All,
I am not sure if this is the right group to post this in - but let me give it a shot.
I have an eVGA NVTV Tuner Card that seem to "play well" with (2)PC's based on ECS K7S5A (Version 3.1) Motherboards - if you are curious about all of the details - do a google group search with NVTV and K7S5A.
No matter what slot I put the NVTV tuner card in, the motherboard fails to detect any devices on the secondary IDE controller. The system also locks up very conistantly with the NVTV board installed and the driver enabled. I can actually restore the "crashed" system by pulling out the NVTV card (powered on) - I realize this is a bit risky and stupid - but I had to try it twice.
So here is my question, what is the best guess on what may be happening
- With the NVTV in ANY SLOT amd with just a video card (NVIDIA OR ATI) cold power on while executing "power on self test" - Primary IDE detects the only hard drive in the system - this is good. With the secondary IDE controller set to AUTO, and just a DVD ROM drive attached, it can't detect it. There is NO INDICATION that the NVTV is grabbing IRQ15? Power off, remove the NVTV card and the DVD drive is detected? Install the NVTV card, power on - DVD drive is not detected. Boot XP MCE 2005, browse for a bit in explore or just leave the system at idle and it WILL CRASH, no errors, nothing reported in the event lock - just a freeze. Disable the NVTV in device manager - restart, guess what the DVD drive is detected now. The system will now run stable - won't crash - obviously the tuner won't work. Enable the tuner, it works - so does the DVD drive - but the system crashes.
Put this same NVTV card into another brand motherboard, it doesn't interfere with the 2nd IDE channel. I didn't test any other functions.
Does anyone think this is some type of PCI bus compatibility issue, would adding external pull up on the control lines possibly help.
This is not a critical issue, I am just up against a budget issue and can't replace the motherboard right now. Any ideas would be great!
