second ethernet interface will not configure using ifconfig
I am having trouble configuring a second ethernet on my redhat machine. I'm not sure about the exact model number , but what I got off of the card is that it is a 3Com Fast etherlink XL PCI. There were also two other specs on the card EA = 0050DA6D3F4F and SN = 6WZ16D3F4F. I'm not sure what those mean. I looked on the 3com website to try to find out what driver was supported with no luck. I have been reading Linux Ethernet-Howto and it says that PCI cards should be automatically detected by the kernel upon boot. When I boot up the machine it says bringing up interface eth1 [OK]. However, when I try to use ifconfig eth1 <IP address> it tells me that there is no such device. I'm confused, it seems like the kernel detected it but it cannot be configured.
