    You have screenshots on the site, since PCI-Z provides all types of Device Manager error messages as well (there is ~40 of them altogether). Since most of them are taken from Windows PE (just to show unrecognized devices), all of them would represent in Device Manager as "Yellow Exclamation Marks".

    BTW, here's one for you: http://oi58.tinypic.com/5upuma.jpg

    Exactly.

    Code:
    mov eax, $80000002
    cpuid
    mov var1, eax
    mov var2, ebx
    mov var3, ecx
    mov var4, edx
    mov eax, $80000003
    cpuid
    mov var1, eax
    mov var2, ebx
    mov var3, ecx
    mov var4, edx
    mov eax, $80000004
    cpuid
    mov var1, eax
    mov var2, ebx
    mov var3, ecx
    mov var4, edx
    will provide a CPU name for you. However, people tend to use CPU-Z (or any similar tool) to get their CPU info instead of picking through EAX-BX-CX-DR registers, converting them to string, printing them to standard output and doing a Google research.

    That is the whole point of the software in the first place - saving time and helping users with limited system administration knowledge.
