Vista disables Cool'N'Quiet on some motherboards

AMD's Cool'n'Quiet support is supposed to be natively built into Vista
(no need for drivers). However, they are finding that C'n'Q setups
that were working fine under XP, no longer work under Vista. People
have been waiting for BIOS updates for their motherboards, and some
have found that the BIOS updates don't fix the problem.

Anyways, it was all a bit mysterious, but it looks like a bit of light
is finally being shown on it: it's Microsoft's fault. The Vole has
very quietly dropped support for ACPI 1.0 tables in BIOS, without
letting anyone know. The ACPI tables are queried by the OS to see if a
particular CPU has support for power management or not. So even with a
BIOS update, they may have still kept ACPI 1.0 tables, and Vista
simply and quietly ignores it. ACPI 1.0 was good enough for XP, so I
have no idea why it's not good enough for Vista.

This just goes to highlight why secretive organizations like Microsoft
should not be trusted. They do stupid random things and people have no
way of finding out what's going on. On Linux, this is not likely to
happen because they wouldn't be stupid enough to drop support for ACPI
1.0 tables -- they'd add support for the newer ACPI versions, but
they'd retain older support too. And if somebody dropped support for
something, somebody else could go into the source code and discover
the problem and fix it again.

Nope, it's not. It's the fault of the mobo manufacturers that simply
don't fix the crap they are selling...

Microsoft has already made clear that Vista would require ACPI
2.0-compliant hardware and BIOS to work properly when they published the
first specifications over a year ago. Every hardware manufacturer that
got surprised by Vista RTM not supporting ACPI 1.0 any more is just an
idiot.

Yeah, sure. Happy little Linux world. Tell that the people that for
example can't get their notebooks to work with everything under Linux.
For example card readers are still prone to make trouble with Linux. But
in this case of course it's not Linux fault but the hardware
manufacturers who don't provide Linux support. Only when Microsoft is
involved it has to be different of course...

Yet, somehow, the beta and RC versions of Vista were all supporting
and working with ACPI 1.0, right up until the end. Why disable such a
fundamental feature in the final version but leave them enabled in the
beta versions? You have all of these beta-testers reporting back to MS
that everything seems to be working fine, and then little do they know
that MS is planning to change at least one other thing without going
through a beta process. What's the point of doing betas, then? These
testers would've likely caught the problem, and Microsoft or the mobo
makers would've issued fixes beforehand.

Wait till you discover that Vista does not use NTLDR any more either.
Vista uses BOOTMGR instead and if you install Vista onto a computer with
more than just one hard drive in it, Vista will load BOOTMGR pretty well
wherever it likes. Not really much of a problem unless you clone your "C"
drive and BOOTMGR is not on it.

Also here's something else that's interesting. It looks like Vista (at
least the Home Premium) has an upper limit on the number of windows
you can open up, just 52 with Aero (and just 54 without).

Because they were *beta* versions? It's quite common that beta versions
contain things that won't be there in the final version. And it's really
not that MS made a secret out of the fact that Vista RTM won't support
ACPI 1.0 any more.

You have all of these beta-testers reporting back to MS
that everything seems to be working fine, and then little do they know

The point is fining bugs and non-working features. Betas are *not* final
code, nor contain they everything that is in the final versions.

If that wouldn't be the case beta versions would be pretty useless...

testers would've likely caught the problem, and Microsoft or the mobo
makers would've issued fixes beforehand.

Nope. The manufacturers of these mobos were sitting on their arses for
over a year while the rest of the world was already aware that ACPI 1.0
is a dead horse. Still they didn't fix their crap.

There are lots of examples where things don't work (especially with
notebooks) even if Linux has been officially supported by the hardware
manufacturer (and this also happened with big names like HP and
IBM/Lenovo). But yeah, here of course it's the hardware manufacturers
fault. But when mobo makers ignored the fact that Vista RTM doesn't
support ACPI 1.0 any more while it was well known over a year before
public release of Vista then of course it's MS fault.

This is like a dead horse, beaten to a pulp, like a B movie I seen
which showed a monster truck running over a dead vampire 10+ times. At
the end you see a blood spot with an essence that their might be a
come back.

Just look at the news, seems a lot of people are upset at how Windows
phones home even if you decline to install the software, not good.
Defending a company who practices marginal ethics is not a very good
position to be in. Yes the motherboard companies are to blame for bad
support, but what exactly does M$ gain from leaving out backwards
compatibility to ACPI 1.0? More DRM control, or some other oddball
effect? Also we are talking about hardware support for cooling and
reduced wattage output which many consider a very good thing to have
support for.

With the new kernel model; ie developers offering to help hardware
companies make software drivers, which in my opinion gets rid of most
excuses if the company is really serious about Open Source. Which does
place the blame on hardware companies, why would I want to buy some
bug ridden non-free Windows only hardware if an Open Source
alternative is around?

Remember how it was with XP? The original release was more like 1st
Beta in its quality; SP1 looked like release candidate; and only SP2
became more or less production strength soft. It's not only MS doing
this - most software made by most companies out there, including the
stuff written by yours truly (gotta admit this), go through these
stages, some of it never even comes to production quality - Lotus
Notes, to name just one. If you want to name more - look at any
flavor of Linux, why the hell the end users have to edit the source
code in attempt (often futile) to make things work? MS is not the
worst offender out there. As for the poor Vista owners - well, they
paid (or piratedLOL/) for the privilege to work for MS as beta
testers ;-))))))
I am not even thinking of installing Vista before SP1 is out, unless I
_need_ it for my next project.

While I'm usually a big fan of backwards compatibility, in this case I'd say
hardware manufacturers are at fault. If you desgin your products such that
it requires "undocumented features" to work then you get what you deserve,
burned (which has started happening more and more on the Windows platform).
On the whole I'd say what Microsoft is doing is probably a positive thing.
Let's face it, backwards compatibility is a source of many of their greatest
troubles... i.e. allowing third party apps to patch the kernel, take over
critical functionality the list goes on... While it's annoying now, in the
end it'll probably ensure a better more secure project going forward. I
guess I should say I'm writing this being in the uniquly lucky position of
A) having a modern system (I"m an enthusiest), and B) have an MSDN
subscription which was paid for me (I'm a developer). So I"m now running
Vista ultimite. I have to say over all it's a great expereince.

When was the last time you looked at linux? The last time I recall
having to edit source code to make something work could have been 4-5
years ago! Things have moved on a LOT since then.

Some of the stories about certain 'features' in Vista should scare the
hell out of anyone thinking about using it. It looks like Vista is just
one huge bloated piece of spyware that will never make it onto my desktop!
