| 4032.1 | It works, but is limited to supported adaptors... | JAMIN::EIRIKUR | Eirikur Hallgrimsson, usually | Wed Jun 04 1997 16:39 | 18 |
| Jean-Paul,
This can only work if the second controller is the Macintosh built-in
Ethernet, or a Nubus board. PCI, PCMCIA (PC Card, CardBus) and Comm. Slot are
not supported.
It the Macintosh has more than one supported Ethernet adaptor, when
Ethernet is selected in the Line Settings dialog of NCP, a pop-up dialog box
will appear allowing you to select which adaptor to use. If this does not
happen, DECnet does not see more than one supported adaptor.
What is probably happening is that the customer's Macintosh does not
have two supported adaptors.
I have personally had a two-adaptor Macintosh, with AppleTalk on one
and DECnet on the other.

| You are aware that DECnet for Macintosh is an End-Node client only so
it can only talk to 1 and only 1 controller.

| Thanks for the quick response.
Well my customer is talking about a 100Mbit Ethernet board, I am not used to
work on Macintoshes, so I do not know if this is not a PCI board, if it is a
Nubus interface, do the transfer speed could cause problems?
Thanks for the clarification,
Jean-Paul.

What type of Mac is it. Given that information, we could tell you if
it is a PCI based Mac or a NuBus based Mac or if it would need to use a
Processor Direct slot (this last is unlikely).
The newer PowerMacs are PCI based.
The first PowerMacs were NuBus based.
The 68K Macs are either NuBus or they have a Processor Direct slot
(PDI) (some have both, and some allow plugging a NuBus adaptor into the
PDI slot). There are no PCI based 68K Macs.

If by some chance your customer has a NuBus based 100Mbit ethernet
board, the board's manufacture would have handled proper hardware
interfacing between the board and the NuBus. Besides if data arrives
too fast for the Mac to digest it is no different than any other
computer using a network. That is to say, packets just get dropped on
the floor and the protocol retransmits the message since it would not
have received an ACK.
But your problem was configuring DECnet to use the board. We assume
that the customer is already using the board for AppleTalk and perhaps
TCP/IP, so interfacing to the hardware is not an issue. It is just
configuring for DECnet. Or did I miss something?
