[HECnet] NT 4 on AlphaServer es40

The AUI port already defines you at 10 Mb/s. You need a different ethernet controller, as the speed is decided by the controller and not the PHY. On the Alpha it does, but I have never tried the VAX, I would think it should, it does in the Stromasys and Simh emulators, but I'm guessing. That is because Alphas actually might have a 100 Mbit/s ethernet controller. No VAX that I know of do. An emulated machine is a totally different topic. There you are still emulating a 10 Mb/s interface, even though it might map towards a 100 Mb/s physical backend.

Why even search the node database? After all, the MOP request holds all the information needed to serve it. RSX don't do a lookup at a boot request. It just serves it. But even so, it is surprising that even a fairly modern VAX can't keep up with a PDP-11 here. Funny thing: a real VAX (VS 4000/60) can't keep up with an EMULATED PDP-11 running in a Raspberry Pi ;) I had to disable service in the emulated PDPs or else they tried to serve the OS to my 4000/90 ;) Really? Are you sure that does not have more to do with the fact that the VAX only has a 10M NIC where as the Raspberry Pi has a 10/100 NIC. I have not clocked the virtual 11/83 on my RPI but the virtual VAX runs at about 1.6 VUPs. That would put it in the VAX-11/785 class - ie not all that fast... -Steve Jordi Guillaumes i Pons jg at jordi.guillaumes.name HECnet: BITXOV::JGUILLAUMES -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
