[ipxe-devel] SAN Boot Windows XP with USB-NIC.

Thanks, Michael.

I tried both ways, but the result is bad.

Still got connection timeout message. Then run the "ifstat" command, it 
showed:
net0: 00:50:fc:8e:c7:8d on UNDI (closed)
  [Link:up, TX:4 TXE:0 RX:0 RXE:0]

Fail to ping the static IP address. Got "Destination Host Unreachable" 
message.

It's weird that by using the same USB-NIC, and almost identical DHCP 
configuration, DHCP function seems to be ok in gpxe.

I will try to connect up a null-modem cable for the next step debugging. If 
you think about any new idea worth to try, please feel free to tell me. 
Thanks so much!

Regards,
Jerry
