I run all of my PCcards at IRQ 9 and all function just fine. But, when inserted, the Xircom always generates the watchdog timeout before it turns on the link LED or transmits any data. From that point, it works fine at IRQ 9. Both Orinoco and Aironet cards also work fine at IRQ 9, so I'm pretty sure that I have no conflict. All a timeout does is to stop the card, then do a hard reset and re-init the card. I assume that there must be a race condition or something similar that prevents the card from properly initializing, although I don't see anything obvious from looking at the source. (Not that I'd be likely to notice, anyway. It's been over a decade since I last wrote a driver and it for VMS.) In any case, I always see one timeout on my RealPort 10/100 card after insertion. R.
