If you connect the MicroVAX ethernet port to a Cisco switch port, check that the Cisco switch port has spanning tree _disabled_ MOP booting and other low level protocols don't cope well with the spanning tree listening period the switch will enforce when the link is reset.

Yes, actually. There Are 2 Cisco switches in the way. Regards, Kari On 15.11.2013 5:55, Cory Smelosky wrote: Hello all, I'm trying to get a MicroVAX II to cluster with MORIA.

There's between 5 and 10 milliseconds of latency between the two...but that shouldn't matter...should it? As I don't have a SCSI Qbus adapter, and I didn't get the TK50+TQK50 with it, I can only MOP boot it. 60M disk is also not a lot. .
