UBoot is the BIOS more or less. None of this helps him since it effectively doesn't have a working BIOS to get that far. I would ping JTAC - pretty sure the unit has a backup uboot image it can fall back to but not having one I have no idea how to get at it myself. Usually there's a jumper or a button one can hit to get the CPU to address an alternate startup location. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
