Whatever happened to x86-64?

My Opteron system is close to 2 year old, and it never ran a single

work that can't possibly be done under 32 bit OS. So far, never heard
of any requirement of 64 bit code in the section of software market in
which I make a living.

There are still very few softw. that support 64, not to mention
_require_ it. I was surprized recently that Half Life II was released
in 64 bit version. However I am not going to run and by win xp-64 just
because of that.

Support it? There is a ton (SuSE is all 64bit). Require, perhaps not.
IMO when we went to GB real memory two or three GB virtual gets a little
close. I've had my laptop shut down short of memory (2GB real).

Now if you need to address 8 GB of memory for some purposes (DB
server?), 64 bit is the only game in town.

Real memory virtual memory. 32bit machiens can only address 4GB (2GB
in most cases) virtual memory, no matter how much real memory they have.
No, we're well in shootin'-range of 64b being necessary.

IIRC the 386 had to wait 5 years for runnable OSes (IIRC, OS/2

There *were* the 386 DOS Extenders and Desqview386 which was a very solid
multitasking environment, long before Windows 3.0 came along or was even
worth looking at. With a coupla nudges here & there, things could have
turned out very differently. In the corporate market, the IBM/M$ "promise"
of OS/2 V1 had a serious effect in slowing down 32-bit Protected Mode
uptake.

I'm sure we still have the "notices" from our big clients warning us of the
requirements for OS/2 V1 versions of our software to fit their scheduled
transition; fortunately we ignored them... never happened. I'd attended
the OS/2 V1 dog 'n' pony show in NYC and I was not impressed... though it
did take some serious "discussions" with our guys "out in the trenches" to
stay away from it. Besides, Phar Lap's DOS Extender was so simple and
DesqView386 was no effort at all - it just worked.

It's an ironic world we live in, when people find you more acceptable
because you're incompetant.

There were good reasons for it to delay introduction of SP2, as they
were trying to fix a leaky boat. At that time security on Windows seemed
like swiss cheese. However, they had x64 finished much earlier, even
though they kept releasing release candidates. They were hoping for
device drivers to be released, but nobody would release device drivers
until Microsoft released the OS. They could've released x64 and still
released SP2 for 32-bit.

Whether they could have or not, is a matter which can only be known inside
M$ - anything else is speculation. They publicly stated that SP2 had
priority and x-64 would have to come after all the security stuff had been
done and proved in SP2. Excuse or reason?shrug

Really the most telling sign that they were delaying was the fact that
Sun Microsystems started development work on their Solaris 10 x64 about
two years after Microsoft, and still released it six months before
Microsoft! One could say that Sun has years of experience with 64-bit
operating systems, and Microsoft doesn't. But Microsoft already had
64-bit source code for Windows in their Itanium port, and other than
low-level assembly language differences, most of it would be the same
between the two architectures, just a recompile away.

If Windows x64 had been released near to when AMD had released their
hardware, even if AMD didn't sell as many chips as Intel, the fact that
a released OS was sitting there it would've been gathering device driver
support ready for the time when Intel came on board. By the time Intel
was ready with 64-bit, you'd have a mature operating system already with
lots of device driver support. And people coming in with Intel would
have had much easier time. AMD users could've acted as the beta testers
for Intel users.

Debatable IMO - I have my suspicions, just as you do, but the "situation"
does have *some* ring of truth to it. AMD still had no momentum and
certainly not in servers at the time. Would the drivers have materialized
for a platform with such a small market footprint?... hard to be certain
from my POV. Even now there are many x64 drivers which are lacking,
extremely buggy or for devices like printers which will never appear.

I'm sure you recall that OS/2 was supposed to do all that stuff while
running on a 286 PC/AT.

Then Intel got themselves the same stick, and the would-be beaters
found something else to talk about. Yes, AMD is doing better now, but
not because of x86-64. Indeed, AMD's increased fortunes have come well
after Intel switched.

Microsoft came out with a Windows XP for x86-64, but the world hasn't
exactly stampeded to get it."
http://www.overclockers.com/tips00910/

I always thought the reason nobody flocked to XP x64 was because
Microsoft delayed and delayed so much to let Intel catch up that people
lost interest in it? I mean you know Microsoft was delaying here, even
Solaris 10 came out for x64 before Windows did, despite starting work
on it 2 years later.

The reason most people I talk to are still running 32-bit WinXP on
their 64-bit workstations is that the driver support *STILL* isn't
there for a lot of their peripherals. Sure, the big name stuff like
nVidia, Broadcom, etc. is fine. However when you start throwing some
obscure hardware in the system you're often SOL.

Of course, that's not to say that Microsoft is totally without blame
here, other OSes seem to have had a much easier time in their
transition to 64-bit drivers. For most it was just a recompile, or at
worst a few patches here and there to make the code 64-bit safe. On
Windows it seems like it's a rather more complicated process.

My outsider's view of it was that there was a big effort on-going at
Microsoft to link up the code-bases from a security standpoint. As
such they wanted to have roughly the same base code (as far as service
packs go at least) for WinXP Home, XP Pro, XP x64 and Win2K3 Server.
Since XP is BY FAR the biggest ticket item/biggest money maker of the
lot, they needed to get that one solidified first. Everything else
could be pushed back behind that.

Again though, this is just the outsider's perspective. What was going
on in the inside could very well have just been complete chaos! :

Yeah well that was the big mistake. Back then even Intel took the stance
that the 386 was only for those "who really needed it" - they thought the
same with 486... and even had a slew of 386 support chips still in the
pipeline when 486 came out.

But "all that stuff" I mentioned included the 32-bit flat memory model -
that was the killer for doing real computing on a desktop. A lot of
mainframe code got converted to Phar Lap's DOS Extender.

I still remember the PS/2 rollout in 1987. I was working for a major
oil company, who was a big time IBM client (millions and millions of
dollars each and every year). One of the big conference rooms was
turned over to IBM, and they had several sharply dressed sales-droids
there to "present" the new PS/2 computers. I remember being totally
underwhelmed that they were trying to sell us 286 based computers.

It still seems totally insane to me that anyone would have spent
serious money to engineer a new 286 computer a year after the 386
computers had reached the market.

Looking back on it all now, it still seems to me that the PS/2 was the
biggest fiasco of the entire computer revolution. I used OS/2 for a
while, and I still think OS/2 was better than Windows 95. But the
PS/2, now that was a fiasco from beginning to end.

It can only be taken as a "big mistake" in hindsight. 90% of the systems
being shipped were 286's and the installed base was huge. ...forgetting
that the '386 was expensive. Dell, you more than most, know that IBM is
all about protecting customer's investments. These systems weren't $400
Dells.

But "all that stuff" I mentioned included the 32-bit flat memory model -

Wunnerful, but that's hardly the point.
