It's an assembly provided by the manufacturer, and plugs perpendicularly
into two in-line edge connectors on the motherboard. Those connectors
are the same type connector as PCI connectors, but have more signals on
them, making them non-standard. The riser card has two PCI slots, an
ISA slot and a Realtek 8129B NIC on it, but no bridge chip. Since the
two PCI-looking slots on the M/B are having to deliver the PCI signals,
ISA signals, and the request and grant signals for each PCI slot and
NIC, I must assume that neither is a "real" PCI slot, and dare not try a
NIC in one.
My "dream" riser would have a bridge for its slots, of course.
Or my dream teensy M/B would have 3 10/100 NICs and a single PCI slot.
Anybody know of one?

The 3COM cyclone devices don't work in the riser either, leading me to
suspect a poor design by my supplier. Slow NICs (the Realteks) and WAN
cards from Sangoma seem to work fine in either riser slot.

When squeezed, the manufacturer admits that there might have been a trouble
report on this once upon a time. They're sending a different M/B and riser
for us to try.
