The card is an ISA one? Only to ISA cards you have to and can pass
resource information for IO and IRQ. PCI cards will detect that
themselves.

So far all looks pretty.

Weird that loopback (lo) has no assigned IP address. Please check the
content of
$ cat /etc/sysconfig/network-scripts/ifcfg-lo
DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback
Many services rely on a proper setup of the loopback device. I think the
other errors are mainly follwing errors because loopback has no address.
