Hi List,

A couple of weeks ago, I asked for help getting a Tulip-based DLink
NIC to work in my DU 164LX box - my original question is given below.
In the end, I went and bought a Digital DE500-BA card which works a treat.

Thanks to: (apologies if I left somebody out ... let me know if it's you)

Apparently, just because a network card has a Digital 2114x chip on
it does not mean that it will work with Digital Unix. The SROM and
the PHY chip need to be considered too. (TL)

Other 2114x-based network cards _do_ work - it is just a matter of
finding one that does. Make it easy on yourself. Buy a genuine Digital
card. I bought mine from http://www.transtec.co.uk (TL)

Of course, before you go and splash out on a new network card, play
with the SRM's ew* variables...
>>> show ew*
Just to make sure that you haven't got (say) a 10baseT card trying
to speak to a 100baseTx full-duplex switch. (TB)

Hi List,

I have a 164LX-based machine on which I have installed Digital Unix.
It has a tulip-based card, a D-Link DFE-500TX Rev-C2, which has a
Digital 21140-AE chip sitting on it. The problem is that at boot time,
it says (among other things):

  tu0: no SROM info for selected media

and it says it in the uerf log too:

  tu0: DECchip 21140: Revision 2.2
  tu0: No SROM info for selected media
  tu0: at pci0 slot 6
  tu0: DEC TULIP (10/100) Ethernet
  _Interface, hardware address
  _00-E0-29-00-B9-EB
  tu0: console mode: selecting 10BaseT
  _(UTP) port: half duplex

and the network doesn't work. The network card has a fine selection
of link lights on it and they all light up as I would expect. The
network just doesn't work. I can't ping. I can't telnet. I can't ftp.
I'm confident that the lack of network is related to this `SROM' error
message: I just don't know what to do about it.

I've tried other 21140-based network cards: A different D-Link DFE-500TX,
with a 21140-AF chip and an SMC Etherpower (I think) card with a 21140-AE
chip. Both give the same error. [Actually, the error above comes with the
SMC card in the machine, not the first D-Link.]

Has anybody seen this problem before and, more importantly, how did you
make it go away? *All* tips gratefully received.

Many thanks,
