My best guess is that the CPLD is not forwarding the REQ signal to the PCI bridge, so the BT878A can't fetch the RISC instructions. But then there is also this persistent ADC overflow... As for the CPLD, there is not much we can do. I count 23 GPIOs going to that chip. And we don't know if some of these are outputs of the CPLD, making it a bit risky to just randomly drive values on those pins. If we had the original software, we could analyze what it is doing. There is someone on ebay.com selling two of those cards and a cd labled "Rescue Disk Version 1.14 for Linux DVR". Daniel
