The bios upgrade from dell is a .exe file that creates floppy disks. I don't have any floppies, is there any way to convert it into a CD iso?
I Ran Dell Diagnostics - no errors, but it really didn't test the functionality of the network card. The only relevant info was under the mainboard test which mentioned that the NIC was present but that is it.
I think the PCI card might be the easiest solution at this point...
