DECnet-capable Gigabit ethernet cards? was created by etmsreec
Hiya,
My PC presently has a DE500 in it for use with the FreeAXP emulator. Are there any cost effective gigabit ethernet cards that anyone is aware of that are capable of running DECnet? IP is easy, of course, but a DECnet capable card would be nice.
Cost effective in this case means reasonably cheap. I could, of course, go for the genuine HP card but the price on that makes me choke!

Thanks in advance

AFAIK a network card is not protocol specific, so any (decent) card will work with the emulator.

The emulator emulates 3 network cards (DE435 and 2 flavours of DE500) which the OpenVMS operating will recognise and load the appropriate drivers at system startup.

In the system I run on my desktop, the emulator (FreeAXP) is set for DE500 (21143) and it maps to the Broadcom NetXtreme Gigabit Ethernet Driver in the system (DELL Optiplex GX620). Works with DECnet, FTP, LAT, etc.

HTH

True that the card shouldn't be protocol specific, but does the card need to be able to have its address changed and/or masquerade as a different address with having DECnet on it? Certainly the built-in Intel chipset on the motherboard doesn't like running DECnet, presumably for the MACaddress issue?

As GaryAgain said, the physical NIC does not impact DECnet support. Other than a couple of Samsung laptops using the Marvel Yukon chip sets, we have had no reported problems with any network cards. The Samsung issue is detailed in section 6.5 of the release notes:

FreeAXP emulates the DE435 and DE500 NICs, so changes to the MAC happen on the emulated device. The physical NIC should have no impact.
