I made a minor mistake, which doesn't do any damage, just reports the
wrong number of total cylinders (sometimes).  On a 20MB drive, the bits
returned didn't cause a problem.  But, a 10MB drive goofed.

Anyway, change the following lines in the DISKREAD.BAS file, after it is
extracted:

' Version 1.1     October 28, 1986
      VER$="Version 1.1"

(The third from last line, in the READPARAM subroutine)

      MAXCYL% = CH%+((CL% AND &HC0)*4)
                                ^

Fix those lines and things will be better.  Sorry about the problem.
