Solaris 10 Dev. Edition - Network config issue (NIC,DHCP,Can't ping router)

Question

I am a developer getting started with Solaris 10 configuration. I recently installed Solaris 10 and have run into an issue with network connectivity.
I have done much research on this and I was able to get communiction to the internet established once, but the settings were lost on reboot.
Overview - The Solaris box is connected to a router which is acting as a DHCP server.
AMD 64 dual 2.6
nForce4+ integrated NIC
1) I am not able to obtain an address from the router. Nor do I get a respons back when I ping it. I get an IP etc if I boot into Windows so phyicial connectivity is fine.
2) Upon reboot the device nfo0 as shown using ifconfig -a has an IP of 0.0.0.0.
3) If I run ifconfig [hostname] my machine gets the ip from the hosts file, but I would like to obtain this from the router.
4) NOTE - the machine shows as active on my router, but the Solaris box cannot be reached from other computers on the networ, nor do I get a reply back when pinging the router from the Solaris box.
GOAL - reach and obtain a DHCP from the router and have the changes stick upon reboot.
/etc/hosts contents
127.0.0.1 localhost loghost
192.168.1.55 solarisX /*<-- this is what I get when I do ifconfig nfo0 solarisX */
/etc/hosname.nfo0
netmask + 255.255.255.0
solarisX
/etc/defaultrouter
192.168.1.254
/et c/netmasks
192.168.0.0 255.255.2550
Specific Steps taken:
Using the driver nfo-2.4.5 locate at http://homepage2.nifty.com/mrym3/taiyodo/eng/ I did the following.
% cd /.../nfo-x.x.x
% rm obj Makefile
% ln -s Makefile.${KARCH}_${COMPILER} Makefile
% ln -s ${KARCH} obj
where ${KARCH} is the result of `isainfo -n`, and ${COMPILER} is
"gcc" or "suncc" which you want to use to make the driver.
4. Testing
Testing before installation is strongly recommended.
# cd /.../nfo-x.x.x
# /usr/ccs/bin/make install
# ./adddrv.sh
# /usr/ccs/bin/make uninstall (for solaris7, don't remove the file )
# modload obj/nfo
# devfsadm -i nfo (for solaris7, use drvconfig and reboot with -r )
# ifconfig nfoN plumb ( where N is an instance number, typcally 0 for first card)
# ifconfig -a ( you will see an entry for nfoN)
# ifconfig nfoN YOUR-HOST-NAME
# ifconfig nfoN ( ensure IP address is correct)
# ifconfig nfoN up ( and then you can test with ping, telnet, ftp ...)
5. Installation
After you ensure that the nfo driver is fully functional, install it.
(1) copy the nfo driver into the kernel directory
# cd /.../nfo-x.x.x
# /usr/ccs/bin/make install
If you do not test the nfo driver yet, execute the following commands:
# ./adddrv.sh
# devfsadm -i nfo (for solaris7, use drvconfig and reboot with -r)
(2) Configure the network interface. Create and/or modify the following file:
/etc/hostname.nfoN
(3) Reboot the system.
# init 6

Answer 1

Thanks Alan. I worked on trying to get the NIC working again last night. I had it working once, although the settings did not perist. I can still get the device to load, but I can't communciate with the router (it's not physical because another OS can reach it.
I took your advice and tried the sys-unconfig. But I did not have much success.
I am wondering if plopping in a new PCI NIC would be the most efficient route to get the server up.
What kind of NIC do you utilize and have had success with?
I am looking at possibly a DLINK DFE-530 or NetGear FA-311. I don't need wireless at this point just a rock solid DEV box.
Thanks again for the previous info.
