I have two PC's which I have networked (win95. cards are 8013ep but can be changed. I also have a Miro DC20 video capture card. When I want to use the Miro card I have to physically remove the network card from the PC otherwise I drop frames on video capture or replay, this is a real pain. I have tried the windows 95 "not in this configuration" but it would appear as long as the card is physically in the machine it caused interrupts. Turning the other machine off makes no difference. There must be a solution to this even if it is solder job with an external switch!!
