PicoBSD

PicoBSD is a one floppy disk version of FreeBSD, one of the BSD operating system descendants. In its different variations, PicoBSD allows you to have secure dialup access, 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, and full source code 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
