1FCD-OpBSD (also known as Karma BSD) is a one-floppy OpenBSD MP3 player with functionality to mount NTFS, UDF (on DVD, CDROM, or external drives), EXT2FS, NFS, MFS, and MSDOS file systems. It plays MP3 tracks, and can copy files from any disk to any disk.

The software may be useful for the blind and it can also be used as a unique utility for copying files over a network (via NFS) or from any file system known to OpenBSD. USB sticks can be mounted as well.

Static OpenBSD binaries can be made on other systems and used with Karma BSD. It is an operating system on a floppy with network support, so no system on hard disk is necessary.
