This is not about diminishing Middleton work. And to be honest, it's
completely unrelated wether it's good or bad quality per se. BIOS is a
highly unstable piece of work, with the potential to properly brick your
box. I admire people working on it, and I do have an experience in
working with low level firmware so I do mean that. But I also know that
you *really* shouldn't just point people to that without the proper
level of warning. Hell, even Lenovo tells you not to update your bios if
everything is working fine, because they do know something bad can
happen and brick your pricy and loved laptop.

Sure. Again, I have nothing against Middleton BIOS more than any other
BIOS hack. And to be honest, I have nothing again anyone working on BIOS
to enable undocumented feature, =E2=80=9Cfix=E2=80=9D the whitelist or anyt=
What I have a problem with is people advertising those to people on
mailing list without the proper level or warning.
This *is* a dangerous operation. Lenovo people know their hardware
better than anyone else. They know the BIOS flashing procedure better
than anyone else. And even with that, they're still not too much
comfortable with it (and there are reasons, BIOS is really a huge pile
of hacks, in a way). So adding a bit of reverse engineered stuff on top
of that, well, it's clearly a gun ready to shoot you in the foot.
It's not a problem when you do it yourself, on your laptop. But again,
it's not wise to advertise it like that. Not to mention the possible

That, by itself, proves my point.

Please, no, it's not =E2=80=9Csafe=E2=80=9D. It might be =E2=80=9Csafe enou=
gh=E2=80=9D for the majority
of people who tried it. And it might be a really small modification
which has no chance to touch anything else than what's intended. The
problem is that, in the end, you don't know. So yeah, it's been safe
enough for now. Until someone bricks its laptop because you pointed it
to that BIOS and he didn't pay attention to what's he's installing.

Well, the original provider didn't enable this for a reason, you know.
The fact that you disagree with that reason doesn't mean it's a bad one.
I don't need SATA2 speed on my T61 so I don't really have a reason to be
thankful to Middleton or anyone else. If some people are thankful, then
fine. But when someone will brick his hardware, he'll only have his eyes
