We are looking at making or OEMing a dual ethernet card for some applications. This should be an ISA card for now.. is there a dual enet ISA card that people have had good experience with. Bare in mind that PIO as used in the NE2000 device can saturate an ISA bus with 2 cards leaving Nothing left over for the CPU or other devices.. (basically the CPU stalls for such a long time per inw() that two full ethernets ensures that there are about 0 cycles of CPU left for any other task. for this reason I'm especially interested in a card/chipset that would support DMA (even cheasy PC DMA), or at LEAST use a shared memeory pool (ISA memory ops are faster than PIO). This app is unfortunatly STUCK with ISA. (things will change however :) Suggestions? julian
