Right- it should be ne. Also, IRQ 5 and an I/O address of 300 are pretty standard; have you configured the card itself for those settings via jumpers or software? If the card doesn't have jumpers, it should have come with some (probably DOS-based) configuration/utility floppy. If you don't have the software, you can try isapnptools
tried the insmod ne irq=5 io=0x300 gives me a list of errors.
5 path fallowed with : " unresolved symbols"
The ne driver is dependent on 8390.o, which must load before ne. Insmod isn't smart enough to know this; try updating the dependency database by running depmod -a, then do:
modprobe ne io=0x300 irq=5
If you get no errors, run lsmod and verify that the driver is in the resulting list of loaded modules.
After that, put the following in /etc/resolv.conf:
alias eth0 ne
options ne io=0x300 irq=5
As far as DHCP goes, you'll need to be running a DHCP client daemon. Augamemcock mentioned pump, dhcpcd is the other common one. Redhat 7.2 uses the graphical utility NEAT (NEtwork Administration Tool) to set up your networking parameters; just type neat at a command prompt to run it. You'll find the option to enable DHCP there.
