Networking is notworking

[Brian Kendig]

I'm trying Fedora Core 2 on my laptop, but it's not able to use either 
of my network interfaces which both worked fine under SuSE 9.0.

The laptop is a Dell Latitude D266XT, connected to its minidock.  The 
dock has an Ethernet connector based on a 3c905 chip.  FC2 properly 
senses this interface and assigns eth0 to it.  But when I try to 
activate it through the Network Configuration control panel, it says 
"Determining IP information for eth0..." then about a minute later it 
says "failed."  /var/log/messages is very chatty during that minute 
it's working; it starts out by logging "dhclient: sit0: unknown 
hardware address type 776" often, as well as things like "eth0: 
transmit timed out, tx_status 00 status e000" and eth0: Transmit error, 
Tx status register 90."  It continues to log errors to the messages log 
every few seconds even after it gives up.

The laptop also has a 3Com Megahertz 10/100 PCMCIA card in it, which 
FC2 also detects and assigns eth1 to.  When I try to activate it, 
Network Configuration says "3c574_cs device eth1 does not seem to be 
present, delaying initialization."  I don't understand how FC2 could 
autodetect a card then say it's not present?  When I try to activate 
eth1, /var/log/messages says nothing about it.

This is a brand-new fresh install of FC2; getting the network up is the 
very first thing I'm trying to do after a vanilla install of it.  I'd 
prefer to be able to get the PCMCIA network card working so I don't 
have to lug the dock around.

Any help would be appreciated!
