I had redhat 7.0 and my NIC card was working. I upgraded to Redhat 7.2. I don't think the kernel is pick up the hardware.

Ichecked the boot.log and found the following:

Mar 10 11:03:27 madmen pcmcia: /lib/modules/2.4.7-10/pcmcia/i823465.o:
Mar 10 11:03:27 madmen pcmcia: Hint: insmod errors can be caused by incorredt module parameters, including invalid IO or IRQ parameters.

When I type lsmod, I get :
