For machines which have an OS installed, you can use an nmap ping sweep, or ARP request to get your local OS to learn other MAC IDs. > I need to discover the machines that are available just with only BIOS > installed (NO Operating System) > > And I need to find the mac address of such machines that are up. Unless a machine starts transmitting any data on the network, you can't find any information about it. If your BIOS attempts PXE boot, you can capture the MAC ID from the DHCP broadcast request. Or if you have a managed L2 switch, you can query its ARP table for list of all MAC IDs it has learned. PC BIOS has limited network support so you really need an OS to do something more useful. - Raja _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
