Thanks. I should be able to translate that to pure assembler in the morning

Hi, I see you got the original code and noticed it does not zero EBX + ECX +EDX before doing the CPUID.
I have found that if you don't do this several elderly CPUs return incorrect CPUID information so advise you to zero the resisters before doing a CPUID.
Do you have an mP6 to test your code on? |

Is there a possibility that the page http://www.cpu-world.com/CPUs/MP6/index.html containing the info regarding the easter egg may get an update in lieu of placement of the NZ string in eax and the order in which the 4byte easter egg chunks are returned?
It is kinda obvious from your code "red-ray" but maybe it helps to add these hints to the info provided by the interview? |

I would suggest you add a comment much as I did. I initially tried setting EAX to 'NZ', but it needs to be 'ZN' and I deduced the order from the returned data.
Does it work on the Lynx CPUs and/or does anyone know where I can get a Lynx CPU please? |

Great  , which OS will you use? W2K or NT4 would be ideal, but W9X should be OK. >= WXP can't be used at all as mP6 CPUs don't have the CMPXCHG8 Instruction.
Would you like to sell me a Lynx CPU?  |

I recently swapped the CPU to a Rise mP6 (Kirin) then booted 2003 Server by accident and much to my surprise it actually booted and looks like it runs OK!
I don't know if a virgin install would work as an AMD-K6 3D+ (Sharptooth) was installed when I installed it. Given XP refused to install I suspect not.
If you have managed to get WXP running with a Rise mP6 I would be interested to hear. |

Some weeks ago, I tested a DOS programme writen by amadeus and found that the Easter Egg is also present in my Rise iDragon cpu (MP65RPAPH4-Q 500MIPS). So it's likely that it also works with Lynx cpus.

Thank you and given this I too suspect Lynx will have it.
I wonder if it's possible to tell an iDragon from an mP6 (Lynx), what does my SIV (http://rh-software.com/) utility report on it's Menu->Hardware->CPUID->CPU-0 panel please? |
