Hi All, I've used this SMC card in a firewall I built once and had a little trouble with it. Here's the problems and what I did to fix it: Problem: works fine in win32, kernel did not see card even though compiled into kernel solution: disable plug & play on card, use manual jumpers (mine was a jumpered and batteried card), jumper to IRQ3, INT10 io300 Then compile driver as a module and load as a module (think I specified irq, int and io on insmod command line) I don't know if there was another way, I'm sure there was, however this is what worked for me. Hope this helps! Mike
