PicoBSD

PicoBSD is a single-floppy disk version of FreeBSD, one of the BSD operating system descendants. In its different variations, PicoBSD allows one to have secure dialup access, a small diskless router, or even a dial-in server, all on only one standard 1.44MB floppy. It runs on a minimum 386SX CPU with 8MB of RAM (no hard disk required).
PicoBSD's use may move from being primarily floppy based to being used more often on systems with at least a small amount of flash storage and perhaps no hard drive.
With flexibility that FreeBSD gives, along with the full source code being available, one can build a small installation performing various tasks, including (but not limited to):
- Diskless workstation
- Portable dial-up access solution
- Custom demo-disk
- Embedded controller (flash or EEPROM)
- Firewall
- Communication server
- Replacement for commercial router
- Diskless home-automation system
- And many others
