No, for a few reasons:

1. I read somewhere on the interwebs that doing so would brick the card
2. I don't have access to a DOS/Windows machine
3. Dodgy hardware isn't what you want when dealing with large databases

If it's not just a firmware issue it wouldn't surprise me if you could
just link a couple of pins/contacts/etc on the card and gain the LSIs
capabilities, but it's not an idea I'd entertain outside of personal use...
