NanoNAS is a Network Attached Storage (NAS) server operating system designed to transform a basic computer into a dedicated HTTP, SMB/CIFS, or AFP file server. It fits on a single floppy disk and is intended for use in any low-security environment or application that requires the simultaneous availability of large amounts of inexpensive networked storage.By design, it is a community workgroup server and does not support features such as user management, disk quotas, or the ability to join domains. However, it is very easy to set-up, to administer, and to use.
BG-Tiny Linux Bootdisk is a Linux bootdisk that does not use a ramdisk, so it will run on computers with very little RAM. It is basically a somewhat extended fork of Tiny Linux Bootdisk. It is based on Linux 2.4 series, uClibc, and BusyBox. It includes dosfsprogs, e2fsprogs, gpart, lilo, and ms-sys. Supported filesystems are ext2, ext3, iso9660, tmpfs, and vfat.
PXE Knife is a tool for booting various floppy based utilities via syslinux, allowing them to be booted off a CD, a hard drive, or over the network via PXE. PXE Knife can be used with a number of commonly used tools such as hard drive manufacturer's utilities, memory testers, Linux recovery disks, Windows password changers, pre-configured PXE Knoppix booters (just add DVD), and a number of other utilities. It takes advantage of syslinux's menu system, so it's easy to navigate.
Brazilfw is a mini-distribution designed for setting up network utility services such as Internet connection sharing, firewalling, or wireless access points. The goal is to make it as quick and easy as possible to set up a Linux system with only a minimal amount of Linux knowledge. The main goal of BrazilFW is to continue the development of what was the Coyote Linux floppy firewall system.
Tunix is a set of tools used to generate small bootable Linux images. It can be used to learn how to roll your own distribution, or to port embedded systems. The basic release uses busybox and has a kernel with netfilter-enabled modules. A uclibc iptables binary is included, so you can roll your small firewall from a floppy.
