Yes, I searched the archives for hours before posting (note the time of my mail). I also track -mobile.

Warner Losh promptly replied with interesting > points to obey in <20020725.231157.73515369.imp@bsdimp.com>. Which problem, the watchdog timeout? My question was why things _worked_. I was looking to better understand what was going on before proceeding. In fact, my guess (see original post) was right on. I have one of those "dumb" PCI->PCMCIA bridges, which makes the Orinoco Silver card look like a PCI device, not a PCMCIA. > Can you try a combination of a bridge and a > card from _one_ vendor?

In the archives I read that PLX would support wi liberally, so I tried it. It does works as I said. My original question was verifying why. > Reading about the "PLX" chip a currency / voltage issue might > be your problem. As for the watchdog problem, I updated the Orinoco cards firmware to v8.? I thought I did this already when I updated the card used by my laptop. I haven't seen a problem since (at least not yet.) I'll look into the voltage later. The box the card came in doesn't have much in the way of those types of details. However, this PCI card is probably going back. I want a "true" PCI->PCMCIA bridge so as to use pcic as I originally expected. Any suggestions (my next post will be asking this very question.)
