I've recently re-subscribed to this list. I'm glad to see you all again.
I read the chain about Cabletron EA41x (SCSI to Ethernet adaptor).
My EA412/19 works fine with my 030 Macs by changing one kernel
configuration. I'd like to tell "how to" and to ask about setting

Yes, the device driver for Cabletron EA41x is sys/dev/scsipi/if_se.c,
the first version was written by Ian W. Dall in 1997.
Now we have new 1.62 2006/09/07.
(Thanks a lot to Ian W. Dall for keeping the driver up to date.)

Cabletron EA412 works with GENERIC(ncrscsi) kernel / Quadra800
without any special setting. It's transfer speed is almost a half of
onBoard sn0. I saw "se0: not queued, error 12" more than 20 times
in this ftp session, but I don't care that because I think no one use
Cabletron EA41x with Quadra. It's very useful for PB1xx, ClassicII
and some LC which has an accelerator on PDS slot.
Unfortunatly, for those 030 Macs (sbc kernel), Cabletron EA41x does
NOT work. Thomas Carlson wrote that details correctly in the chain;

GENERICSBC kernel users see the next line in the dmesg;
>sbc0 at obio0 addr 0: options=1<PDMA>
This 'options=1<PDMA>' let Cabletron EA41x fall asleep.
I don't know the reason why, anyway, I rudely changed this option
in my GENERICSBC kernel config file;

With changing sbc0 flags 0x1 to 0x0, yes, that's all, very simple and
Cabletron EA412/19 wakes up and works lively with my ClassicII,
LC (serial console / 030 + FPU accelerator) and LCII. :)
