It is a harmless memory resident boot virus. The virus infects the boot sector of floppy disks and first boot sector of the C: drive. While infecting a boot sector the virus searches for the string "non-system disk" (any-cased) in there, and replaces the following texts with the virus installation code (40 bytes). Then the virus writes its main code to the last sector on the disk.
While loading from an infected disk the virus installation code reads the main virus code and jumps to there. Then the virus hooks INT 12h, waits for DOS loading process, then hooks INT 13h and infects the disk boot sectors that are accessed.
The virus contains the encrypted text strings:
LOVE
non-system disk
