Who made the interphase device (the mobo)? Maybe you can check their site and find something. Other than that, your best bet would probably be a third-party non-OS utility that will boot your computer itself and test from there. ...or you may accidentally be able to do it from your BIOS (some actually can do that, especially the IBM Thinkpads! ...but don't hold your breath looking there.). Hard Drive manufacturers may also be a good source, but match the utility with whoever made your drive. FreshMeat or Google may be your biggest allies for this one.
...maybe Tucows can work their way in as well, but their search tool is pretty picky.
