Certain, older versions of the 80386 CPU have a bug known as the "B1 
Step Bug", they are often known as a "B1 step 386". These B1 step 386
chips are sometimes found in older model 386/16 or 386/20 machines. The 
beta-1 release of Chicago will suffer from seemingly random failures if 
it is run on a B1 step 386.

Because of this, we are posting the B1TEST.EXE program to test your CPU 
and tell you if you are running on a B1 step 386. Please run this 
application from within Microsoft Windows. If it detects a B1 step 386 
in a computer, you SHOULD NOT install Chicago on that machine. When you 
run B1TEST.EXE, it will return with one of the following messages:

        "You have a 486 (or higher)"

        "You have a 386"

        "You have a B1 step 386"

Again, if you have a B1 step 386, you should not install Chicago.

The program is in Library 1, Fixes and Updates, as B1TEST.zip.
