We are trying to make one of our R210 II appliances to boot from our PXE server. The problem is that once we tell the machine to boot using PXE, it tries to find the PXE server but never sends out a DHCP request. We have confirmed this by running tcpdump on the router interface to which the machine is connected. Since it never gets an IP address, PXE does not work. Any suggestion as to how we can make the machine to request a DHCP lease?
By the way, we are running BIOS version 2.5.1. There have only been some PXE fixes in BIOS version of the 2.1.x branch.
