/*

Modifications:

01.10.94    Joe Holman  Added DISK_TO_START_NUMBERING_AT because
                we now have 2 bootdisks, thus we to start
                making floppies on disk # 3.
01.11.94    Joe Holman  Change value back to 2.
05.05.94	Joe Holman	Change # to 1.
06.10.94	Joe Holman	Made CD specific changes.
07.21.94	Joe Holman	Added code to check for textmode/gui-mode disk swaps.
