why enable in the bios?
I've been frustrated with servers recently myself, which seem to come with VT disabled by default and I have to go enable it on each box. Is there an advantage to having it disabled? Why would anyone set the option to disabled by default?
Same goes for "Intel I/O AT", disabled by default at least on the most recent Dell systems that we have, any reason to have it off by default? I mean if you have software that doesn't take advantage of it you won't be able to take advantage of it anyways, but what's the point of having it default to off especially on a brand new server?
Desktops/laptops too, I can't imagine a reason not to ship with VT enabled by default.
I turn VT and IO/AT on all boxes regardless if I ever think I'll use them right away. I just haven't seen a reason not to.
