Enable CPUID on Cyrix 6x86 CPUs

[hardwarecop]

Hi all,

I've some problems with CPUID detection on Cyrix 6x86 CPUs that I couldn't solve yet. AFAIK the CPUID instruction was disabled on the Cyrix 5x86/6x86 by default. I've found various programs on the web which can help me enable the instruction, here's one of them:

http://www.paradicesoftware.com/specs/cpuid/note_cpuidtroubles.htm

Unfortunately this program (and all the others) don't work for me. I'm trying to get the CPUID of the CPUs on a QDI Titanium IB+ with Windows 2000 and XP Professional (I can choose between these two OSes) running on it.
Do you think my operating system is too modern?
Because these programs are written for DOS. Maybe I should downgrade to a MS-DOS based operating system, such as Windows 98/95?

Here's an example I have found:

http://www.cpu-world.com/CPUs/6x86/Cyrix-6x86-P150%2BGP.html

So it has to be possible!!

I've also found some assembly codes(?) on the same website - I don't know how to use the code. I never studied informatics or low level programming languages - maybe you can give me some advices...

Thankkkssss alot!!!
Frank

Okay, thank you very much for your reply.

How does the autoexec.bat thing work? Wait, I'll google first

So according to your text it may not be possible to read the CPUID with CPU-Z because CPU-Z uses a GUI which is running independently from CMD.exe?

I think that enabler utility will not work on Win NT/2k/xp, but I´m not sure.

There´s a bios option on some Socket 7 motherboards called Cyrix CPUID Enable/Disable. So check your bios settings.

Or you can install Win98, enable CPUID by DOS utility and run CPU-Z for Win9x.

The CPUID code I wrote some years ago never uses CPUID for Cyrix processors, but it constructs and ID code from the info contained in the chips registers. It can identify most steppings of all Cyrix and compatible processors. I'm not sure if it's currently available online though. I'm sure I could find it for you if you need a text mode ID app.

the data from it was very handy, that I do know

what I use especially for Cyrix based processors that disable CPUid by default and also supplies DIR info on them

comes in DOS & Win versions

and it is one of the few programs that reports the correct L2 info for all VIA C3s

Okay, thanks, this seems to be a great page.

@misace: Unfortunately there's no such setting in my BIOS - I have also tried many other motherboards I have - without success. But thanks for the answer!

I'm trying everything with W98 again.
