I received mine yesterday and promptly checked out the BIOS. It does appear all the S, Q and X series use the same BIOS and the BIOS says it's an X202E. The original factory sticker says Q200E. The BIOS string doesn't list any model, but the motherboard S/N on the ad-hoc label shows up in the BIOS.
Everything was as advertised, except for one thing, and that is, it only came with Fast Ethernet, not Gigabit as the specifications identified.
So, it goes back.
