Well, I guess I still can't find the report I need.
So, I again request others to send me reports from
both 486s and Pentiums (no PII or PPro please).

btw: Thanks a lot to all those who sent the output.

Here's the program:
------------------
#include <stdio.h>

unsigned idflag()
{
 register unsigned long eax __asm__("ax");

 asm("pushfl;
      popl   %eax;
      orl    $0x200000, %eax;
      pushl  %eax;
      popfl;
      pushfl;
      popl  %eax;
      andl  $0x200000, %eax;");

 return (eax);
}

unsigned long cpuid(unsigned fn)
{
 register unsigned long eax __asm__("ax");

 eax = fn;
 __asm__("pushl %ebx;
          pushl %ecx;
          pushl %edx;
          cpuid;
          popl  %edx;
          popl  %ecx;
          popl  %ebx");
 return (eax);
}

int main()
{
 register int level;

 if (!idflag()) {
    printf("Sorry! No CPUID.\n");
    return 0;
 }

 printf("CPUID level = %d\n", level = cpuid(0));
 if (level) printf("CPUID value = %lX\n", cpuid(1));
 return 0;
}
-----------

Thanks in advance.
