No network after the installation of a Solaris 9 u4 on Intel...

I checked the /var/adm/messages
it complains about unqualified hostname
unable to qualify domain name with hostname in short

and I tried ifconfig -a
and it only list the lo0 entry... which I know from Linux, it means the only interface is the loopback...
so I suspect that Solaris didn't even detect my network card...

Any suggestion is appreciated
Thanks in advance.

1. check if your NIC is on the Solaris 9 (Intel) hardware support list:

   http://www.sun.com/bigadmin/hcl/

2. Have a look at the following pages for instruction about how to config the NIC:

  http://oldlook.experts-exchange.com/Operating_Systems/Solaris/Q_20667493.html
  http://oldlook.experts-exchange.com/Operating_Systems/Solaris/Q_20277981.html

  http://oldlook.experts-exchange.com/Operating_Systems/Solaris/Q_20547371.html

  PS: in term of installation of NIC, all version of Solaris X 86 are the same, except
        Solaris 9 support newer hardware devices (please the the HW sopport for
        Solaris 9 or Solaris 8)

tried the suggests on the URLs listed...
but still no luck...
ifconfig -a doesn't list anything other than lo0
on one of the URL someone suggested snoop
but still it comes back no network device detected...
try detect hardware again on the boot up, it does list the PCI Ethernet Realtek 8139
and it is in the HCL list...

And I'm sure the hardware itself works, coz it works in Linux and Windows right now (with multi-booting)

After trying another driver, finally got it listed in ifconfig -a as rf0
and with the ip address I specified
but when I ping any ip in local network or outside, all are unreachable...

I connect to Internet with a router
and I specified an ip for Solaris
and I put in DNS address

works after I do a sys-unconfig
and then edit the /etc/hosts to set the local ip instead of the external ip
and now both internal and external and DNS resolves works perfectly
