No. I think this Easter Egg is as valuable as an MP6 ES processor

I think Easter Eggs are cool. Great to know about this one - I might even incorporate it when I get round to updating my CPUID code

I agree!! I love easter eggs! I also like hidden graphics on chip die |

Clearly he went to a lot of trouble to incorporate this. Love it!

The companies who you work for frown.
Especially Microsoft - it's practice is banned. |

Easter eggs are generally banned because they are hard to debug.
Since the debuggers do not know they exist, ALL test cases cannot be tested.
Easter egg code can (and sometimes does) open new flaws and/or vulnerabilities that then can be missed in final testing, espectially in an application with hundreds of thousands of lines of code

|
|
I just got a Rise mP6 (Kirin) as I liked the idea of a CPU Easter Egg then updated my SIV utility to report it. I am now wondering if it's just the Kirin that has this or if it's in Lynx as well.
Has anyone managed to get Windows XP to run on a Rise mP6 (Kirin)? When I tried to install it this was not possible as the installation reported that the CMPXCHG8 Instruction is needed which the Rise mP6 does not seem to have. I already had 2003 server setup, but that will not boot when the Rise mP6 CPU is installed. |

Is there any chance that anyone still has the cpuidnz.asm file? I can't find it in my archive.

I could not find it, but below is the code I used to read it
| Code: | siv_cpuid( 0x00005A4E, 0, &cpu->cpNZ ); //
ci += stprintf( ci, TEXT( "\n" ) //
TEXT( "\n\t00005A4E\t%08X\t%08X\t%08X\t%08X" ), //
pmi[ 3 ] = cpu->cpNZ.eax, // "ie *"
pmi[ 0 ] = cpu->cpNZ.ebx, // "* Ch"
pmi[ 2 ] = cpu->cpNZ.ecx, // "Norr"
pmi[ 1 ] = cpu->cpNZ.edx ); // "ris "
VOID siv_cpuid( // Execute a CPUID Instruction
ULONG ieax, // CPUID Number
ULONG iecx, // CPUID Level
CRDB *data ) // return data
{ ULONG teax; // temp EAX
ULONG tebx; // temp EBX
ULONG tecx; // temp ECX
ULONG tedx; // temp EDX
__asm mov eax, ieax // set the CPUID Number
__asm xor ebx, ebx // zero
__asm mov ecx, iecx // set the CPUID Level
__asm xor edx, edx // zero
__asm _emit 0x0F // do the CPUID Instruction
__asm _emit 0xA2 //
__asm mov teax, eax // copy to local temps
__asm mov tebx, ebx //
__asm mov tecx, ecx //
__asm mov tedx, edx //
data->eax = teax; // copy to user block
data->ebx = tebx; //
data->ecx = tecx; //
data->edx = tedx; //
return; // done

I need to see it in a pure x86 assembly language. asm extensions to high level languages are not as easy for me to read, due to only knowing ANSI C and std C++ and being too old to figure out too much new stuff
