Packet Driver V.7, which is the current version we use, does not support 3c503 with shared memory disabled, which is rather annoying, since we have SW that demands that shared memory is disabled. Everytime we used Packet Driver, we had to open the PC's and restrap the 3c503 card. The Packet Driver V.9 for 3c503 is supposed to support 3c503 with shared memory disabled (using CPU i/o transfers to move frames - not DMA), but after the first few receive interrupts from the card, the packet driver freezes inside the ISR with interrupts disabled (effectivly stopping the PC). Have anybody gotten PD V.9 for 3c503 to work with shared memory disabled ??
