hallo,
we wanted to switch to fast ethernet on our 433au with DU4.0D, but
just got "no SROM info for selected media" error messages.
thanks to

for their quick response.
the card we got installed from deq is only for 10baseT and 10base2.
we got the original 100baseTX card separately. we connected it to
MII (instead of MAU - as Fulvia Costa pointed out) on the riser card
and everything went well.
our switch did not detect the 100mbit FD and defaulted to half-duplex.
setting to full-duplex and avoiding auto-negotiation helped.
yours,
andreas bunten
