I've never encountered inherent problems running multiple NICs on
an EISA bus. One of my clients runs four 16mbps Token-ring networks
off of one Dell PowerEdge EISA box.

What I have encountered in my past is Accton's lame engineering,
though.

I once maintained a PoS/2 model 80 on a LAN with one Ethernet and
one 4mbps Token-ring. The Ethernet side was using an Accton NIC,
and the server constantly abended, lost connections, etc. This was
not a powerful or demanding machine, remember - a 386/20 with
Microchannel bus.

We replaced the Accton NIC with a 3Com 3C523 (made no other changes)
and everything was fine thereafter. From that point on I never used
an Accton NIC in anything more demanding than old workstations.

I think Accton tech support is making excuses for an inferior
product.
