I cannot use the Xircom CEM56 modem+ethernet PCMCIA card on my Latitude CPt V400GT; Note that the same card works without problems on my CPt 466 GT (but it has differents sound and video cards). The problem is that when I insert the card, I get a "failed IRQ3" error; I tried to modify the setup in /etc/pcmcia/config.opts, and in particular I used the same values of the Windows98 setup. Unfortunantely evrerything was useless (..."failed IRQ x" ..."no avaiable port" ..."no avaiable memory" and many others errors!) Thanks in advance for any suggestion. Giancarlo Sangalli.
