Thanks Till, that configuration works fine with me.
I still don't know what is the problem with the configuration i was
using since i was able to get network with other guest systems.

I really don't recall major problems with the ne2000_isa emulation.
Here's a script I use to start qemu. It contains a few comments (don't
remember the details but I do remember that you have to change the
interrupt number in your network interface configuration):
# CAVEATS: qemu has irq hardwired to 9; must set this in RTEMS network
configuration table (irno:9)
# rtems application must not set ethernet address (would be
unknown to qemu dhcp)
i386-softmmu/qemu -M isapc -s -L ../pc-bios -net nic,model=ne2k_isa -net
user -cdrom tst.iso -tftp boot -redir tcp:4444::4444 -redir
tcp:2159::2159 -redir tcp:24742::23 -hda img -boot d
