I am using tftpd32 on xp as server.
qemu 0.9.0-win32 can't boot from nic.

I have tried use vmware .It is OK.

so I download etherboot iso image from rom-o-matic use the pcnet32 nic card.
this iso can boot vmware use PXE.
but when I boot qemu-win32 use this iso.It tell me "No Ip Address".

The qemu use -net nic,model=pcnet -net tap.

I have used ethereal capture the packets on tap device.
The DHCP offer packet is sent.

who can help me?

Can you try using the other nic types? I'm most interested in the 
results with the rtl8139 model.

I have used rtl8139 the first time.Does not work.

I think the etherboot is OK. because I can use it to boot from vmware.
and the ethereal captured the DHCP offer packet on tap nic.
How the tap-win32 and qemu deal with this packet?
I can't trace it.

You're using tap-win32? I have no idea how well tap-win32 works with 
PXE... That would be my suspicion.

qemu doesn't do anything with the network traffic. It just passes it on to 
your host OS. This is almost certainly a bug in your host networking 
configuration. i.e. you don't have a dhcp server listening on that interface. 
Configure it exactly the same as you would on a real network/machine.
