Fab,

You almost got it right:

found on the MT23208.  Someone form Mellanox

Tavor is the MT23108 chipset (PCI-X), Arbel is a PCIe chipset which
comes in two flavors:
MT25208 - Arbel in Tavor mode (fully compatible with MT23108, has local
attached memory connected to the chipset).
MT25218 - Work without local attached memory (mem free), from SW
perspective looks different from Tavor mode therefore requires modified
driver.

Hi Jeremy,

Bring up the computer management console (right-click my computer,
manage), then select Device Manager.

Find the HCA (probably PCI Device under Other category), right-click,
properties.

You should see a "Details" tab, select it, and select Device ID or
Hardware ID.

The drivers should work with:
PCI\VEN_15B3&DEV_5A44&SUBSYS_5A4415B3&REV_A1
PCI\VEN_15B3&DEV_6278&SUBSYS_627815B3&REV_A0

The first is a MT23108 board, the second is a MT25208.

Let me know what your device is reported as (select the hardware ID,
then ctrl-c as the right-click menu doesn't give the option to copy) if
it isn't one of the above.

Yes, if your Windows box is the same, it should work.

Correct - Tavor is the PCI-X HCA chip from Mellanox, found on the
MT23108 HCAs.  Arbel is the PCI-Express HCA chip, for HCAs with memory,
found on the MT23208.  Someone form Mellanox will hopefully correct me
if I've bungled this up.

If your system is PCI-X, you have an MT23108.
