Yes, it does. You just don't know what they're called, and Redhat's
hardware autodetection is pretty sad compared to some other distros'.
(Knoppix's hardware detection is top-notch, f'rexample.) Autodetection
of ISA cards is a total pain and nothing does it very well.

3Com 509 cards use the "3c509" module; you just enter the command
"modprobe 3c509 irq=N" , substituting the correct number for N (whatever
ISA IRQ you've set the 3c509 card itself to, using jumpers or
3C5X9CFG.EXE or whatever.)

DEC 21*41 cards use the "tulip" module. Since these are PCI cards, you
just do "modprobe tulip".

After you've loaded the correct kernel modules for your hardware, you'll
need to set the Ethernet interfaces' IP addresses and routes. To assign
a static IP to Ethernet interface eth0 , you do:

ifconfig eth0 X.Y.Z.W netmask A.B.C.D broadcast E.F.G.H up

...replace the capital letters with numbers, obviously. To set a
default route, do:

route add default gw A.B.C.D

...replacing A.B.C.D with the IP address of your default gateway. To
get an IP for Ethernet interface eth0 via DHCP ("Automatically assign an
IP for this interface"), do:

dhcpcd -d eth0

If you're setting up a gateway, you will need to read the
IP-Masqing-HOWTO. It's at http://tldp.org/ in the HOWTO section.

Lesson 0: The hardware manufacturer's website is typically the *last*
place you look for Linux support. The first thing you should do if you
have a piece of hardware of brand $MAKE and model number $MODEL is
Google for "$MAKE $MODEL Linux".

It's in /lib/modules/$KERNELVERSION/ somewhere, and it's called
"tulip.o" .
