I think MS means Mac OS/2 etc. although that's a bit confusing. I searched Asus worldwide and didn't come up with anything at all anyway.

What gets me is, why on Earth doesn't Samsung's website know about their own drive? I can't find it listed.

I no longer have a TSST drive but when I did I used a utility they have for download on their website that you install and when you run it it tells you what TSST drivers and firmware are needed if not already installed.
It's called "LiveUpdate".
