X-class and no original HP CPU?

I have an x-class with intel PIII FCPGA 1GHz working well, the only
thing is on booting the error Message:

0031: Unsupported processor stepping - no microcode update loaded

Because I want use the system working as a server it is a hard doing to
press F1 for complainig this message while doing an remote reboot. So i
want to lose this message without buying such an exorbitant expensive
original HP CPU.

Any suggestions?

Here are the specified Information about the workstation:

HP X-Class A1280
BIOS: ID.W2.02US

First, try a BIOS upgrade if one is available.

Is the 1GHz CPU original? Probably not. What speed was the original CPU? The
problem here may go beyond processor stepping. Make sure that the motherboard
can support the operating voltage required by the 1GHz CPU. Intel began
shipping lower voltage CPUs somewhere around 1GHz... Ben Myers

Hi,

unfortunately there is no offical newer BIOS version :-(

No original Part. I have tried an PIII from an Lc2000 wich works fine,
but this FCPGA CPU was never supported by HP.

The CPU Specification meets the HP requirenments totally! And everything
working very well only on reboot the question for pressing F1 ... :-(

Until now I´ve found a similar Problem but the Auther has now more HP
Hardware for supporting :-( if there is anybody who is interesting in:

Now and then, one comes across a very picky BIOS which will only accept certain
CPU steppings. HP did this and also used some quasi-proprietary memory in its
servers, adding a bit of logic to identify it as HP memory. Generic non-HP
memory would work just fine after the BIOS displayed a message saying that
memory was not HP. Some of the other companies with a history of proprietary
offerings have played similar games with disk drives, CD-ROM drives, memory, and
CPUs. The whole idea is to get you to pay a lot of money for ever-so-slightly
customized parts.

I have encountered some IBM systems in the past which would complain about the
CPU stepping, but if one reflashed the BIOS with the same BIOS version(!), the
BIOS would no longer complain. You might try flashing the BIOS with even the
same version.

Otherwise, your choices would seem to be to live with a CPU that works or to
experiment with as many CPUs as you can find until you find one that the BIOS
accepts without error... Ben Myers

Well, You don't need a "HP CPU", the A1280 works with generic Slot1
processors (HP has no "special versions" of Pentium3 processors either)...

The problem is that the BIOS doesn't know the CPU and also doesn't have
microcode for Your processor. It might just be a cosmetical problem (a
stupid error message when booting), but the microcode which gets loaded into
the processor at boot time is very important for the processor working
correctly and without performance bottlenecks...

Since You won't find a BIOS that supports FCPGA processors for the A1280 I
strongly suggest You try to find a suitable Slot1 CPU...

That's also the case with several Fujitsu Siemens PCs. The reason is that on
these systems the BIOS and the microcode are separate files, and the flasher
only loads the microcode appropriate for the installed CPU. If You change
processors You have to reflash to get the right microcode on the system...

Unfortunately, if my memory serves me right this won't work. HP, like most
PC manufacturers, had BIOSes which contained all supported microcodes in one
file. So You don't need to reflash after a CPU upgrade...

With some IBM boxes, reflashing the BIOS with an installed CPU (supposedly
unsupported microcode and stepping) makes the BIOS complaint go away. Go
figure. Apparently the microcode is embedded within the flash BIOS module
somewhere.

I happen to like top-posting. It allows me to immediately read what the last
poster had to say, and I don't have to scroll down thru the entire thread to get
to the last response. Top- and bottom-posting are matters of preference, not
religious or historical UNIX dogma... Ben Myers

I know - as I have said a PIII FCPGA CPU is used. :-)

Could you explain - so that a stupid guy like me could understand ;-) -
what the hell this microcode is doing? I mean anything other but to
identify that the Processor is or is not from hp.

I wish that error message to hell, everytime I reboot the system my wife
get´s an heart attack because the speaker is so unbeliveable loud! ;-)

??? Until now I thought the intel Processors are all very static things
and nothing is uploaded to them. The only concepts where code is loaded
to an CPU I know is transmeta and such similar Processor familys. In my
opinion the BIOS has the task to make the system optimal work with the CPU?

Apart from the "press F1 Key" Problem after reboot (and the huge medical
Bill for my wife ;-)) there is no real Problem. The System works really
fast and no other Problems are seen, I used it for a long time for a
gaming machine until I´ve bought a PIV System.

Hi,

good Idea but doesn´t help. I have flashed the BIOS again - with the
actual CPU - but it doesn´t help. :-(

It is a little bit frustrating, it is a nice and powerfull System and
such a little Problem could peeve you so.

I´m glad of using unix so I have not boot so much times ;-)

Greetings

In the most simple terms, microcode is primarily Intel's way of correcting
errata in the chip design. The microcode is special code, not at all i86
assembly language, that gets loaded into the CPU, either by a flash BIOS update
or a specialized program. The HP BIOS apparently checks both the processor
stepping and microcode to make sure that both are supported by the particular
model. This means that HP engineers and test lab rats have spent the extra time
running extra qualification tests on the given combination of computer
equipment.

With servers and somewhat specialized workstations (like X-Class), the
manufacturers make sure that certain combinations of processor, microcode, and
other hardware work well together. Doing so is part of the justification for
charging a premium price for the computer. When a server is supposed to operate
24/7 or maybe a workstation is supposed to do the same in some hospital lab
environment, buyers are willing to pay a premium for high reliability. The
specific combinations of stepping, microcode, maybe RAID controller firmware
level, and hard disk firmware revision level are SUPPOSED to make for a highly
reliable system. Do they actually contribute to higher reliability? I wonder
sometimes... Ben Myers
