Hi Mark, Thanks for teh Info.What do u mean by proting for the ARM board,Since This board is required to connect to the internet shud I be Writing a device driver for it or does it already have a working driver for it.I wud like to know whether there are any Buses on this board like PCI thru which the network interface is conencted or is it hardwired into the System without a BUS.Moreover the Application layer and TCP/IP layer cannot as of now be fitted onto the Board.I wud like to know what suggesaions you have for this problem.Thanks.George --- Marc Hinrichs <fuffzig@marcfuffzig.de> wrote: > Am Dienstag, 27.
