Check CPU in FreeDOS

There are a lot of tools to get information and to measure the speed of your CPU, here is one which I think is compact and useful: CHKCPU    
It can be downloaded from http://web.inter.nl.net/hcc/J.Steunebrink/chkcpu.htm. Copy it to your FreeDOS machine and start it like this: 

C:\>cd INSTALL
C:\INSTALL>unzip CKCPU121.ZIP
...
C:\INSTALL>CHKCPU.EXE

 CPU Identification utility v1.21         (c) 1997-2012 Jan Steunebrink
 ----------------------------------------------------------------------
 CPU Vendor and Model: 'classic' 386
 Internal CPU speed  : 16.0 MHz
 CPU-ID Vendor string: - No CPUID -
 Current CPU mode    : Virtual

When I release the 'Turbo' button on my case I only get the following:

C:\INSTALL>CHKCPU.EXE
