How to use LevelOS_floppies:
Step 1. Copy the contents of these directories to separate floppy disks. 
Step 2. Label the disks accordingly, e.g. 1 should be named "LevelOS Disk 1", 2 should be named "LevelOS Disk 2", ...
Step 3. Make sure the target computer has atleast ONE (1) disk drive attached.
Step 4. Insert disk 1 into the drive, then run setup from its drive directory.
Step 5.1. In Minecraft: Follow the instructions on screen. If it asks you for the next disk, insert it.
Step 5.2. In an emulator: Attach separate disk drives for every disk. Make sure you've put disks in those drives! Note which disk corresponds to which drive (check info.txt in the drive directory). If it asks you for the next disk, type the correct drive directory (such as disk, disk2, disk3, etc.)
Step 6. Restart and enjoy LevelOS.
