Probably this question has come up before, but I need an answer. Is it true that an X station cannot boot across the network when there is a bridge in between? Is there a work around? We have some X stations coming. It is a kind of useless if they must be confined to the same loop (building) of the host.

Is there a work around? Well, some wild guessing here:- As you need to tell the boot-server the E-net address of the X-station it may be that your bridge is unable to fake the X-station (because the bridge may not know about the X-station if it is quiet, but that seems unlikely..). If this is the case, then the work around is simple, and that is to provide the bridge with a filter table entry for the X-station, so that it doesn't need to learn where the X-station is. Alternatively, the TFTP may be unable to work at the speed and/or time delays between different halves of your bridge. This is unlikely if you are using a local bridge. The work arounds here include: Giving higher priority to the server packets; Getting a higher bandwidth pipe between the halves of the bridge. >We have some X stations coming.

The Xstation Manager software that runs on the RS/6000 restricts booting to the local ring (will not cross bridges).
