#    Derived from:    Template supplied by SGI for hot mix installation
#            and the SoftPC HotMix scripts.

#
#    Purpose:    To act as a wrapper for the installation process from
#            the hot mix CD. This script is called from InstallIt
#            which opens a window as root to run this script in.
#            This script asks various questions, calls instwrap
#            which runs inst and supplies its input, and
#            can optionally check your floppy drive and CD drive
#            to see if it is configured correctly for SoftWindows
#            - i.e. no msdosd or mediad running on it.
#


# We must first find out whether to use msdosd or mediad for floppy status
# checks. We do this here so the getfloppy() function can print out the
# correct message.
