Hi everyone,

   I needed to get some details about the CPU
information on a 486DX4. I couldn't find one to test
this. I would be grateful if you guys could send me
the output of this program to me. People with access
to any 486s can also send me the reports.

Here it is:
-----------
#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;
}
-----------

Thank in advance.
If possible, please CC to me as well.
