The latest disks from Interactive and Intel (Version 3.1) include a question
about Erratum 21 in the installation procedure. Basically the INSTALL
script asks whether the 80386 being used in the system has "D step" or
after 80386. A special software patch which fixes the FP problems will
be installed if you respond with a "Yes you want the patch applied."

If you don't have a 80387, or have a D step 80386, the patch doesn't
need to be applied.
