To collect some more data I continue (even if it is complicated) to use the embedded DIGITAL 21143 Controller. Somtimes the connection works with 100Mbit/sec ! The only Problem is the startup as soon as the connection is established it stays very stable. On the UX164 only ARCS Bios is available but I will check the SRM settings on the AU600 next weekend. Tried also a 2.2.20 Kernel which works even with the cable connected but only at 10Mbit. Thanks,Ian

I can remember having experienced some issues/influences with what is
set in the ewaX_mode SRM variable of the ethernet adapters, but I
can't remember which one it was and what driver/kernel I used at that
time (might have been 2.2.x kernels). You might try to use another
value your ewa's mode. For DE500-BA adapters I have currently set it
to "Auto-Negotiate" and for DECchip 21040 adapter to
"Twisted-Pair".
You might try others like
>>>set ewb0_mode help
bad value - valid selections:
Twisted-Pair
Full Duplex, Twisted-Pair
AUI
BNC
Fast
FastFD (Full Duplex)
Auto-Negotiate
My machine's network cables are always connected and SRM Auto-
Negotiate works quite well during startup.
