I actually like Sony, Alot of posts and comments are always bagging it, but if you can get one, I recommend it.

One thing I ALWAYS hated about Sony, is the lack of options in the BIOS, actually almost none. Then I discovered this Post. This will enable you to enable VT (which Sony disable citing some stupid reason) and typically me being the inquisitive type I wanted more.

I found another Post (Japanese) that had a similar option but with a new address. This will enable alot more options, I mean ALOT.

here is the run down.
