Important: The next screen that appears will appear
only briefly, so you need to know what to look for
before we continue. The screen that will appear is
called the IBM Color Bar screen. When it does appear,
your IBM PCyr begins to test itself. While this test
takes place, the amount of memory being tested
appears in the lower right-hand corner. It will start
with 4KB and end with either 64KB or 128KB,
depending on the amount of memory installed. Make a
note of the final memory message when it appears. Go
to Step 3.
