andLinux is a complete Linux system which is seamlessly integrated into Windows (running on Windows 2000, XP, 2003, Vista). It uses CoLinux as its core, which is a port of the Linux kernel to Windows. That makes andLinux run more efficiently than Linux on an emulated PC.
In 2008 and 2009, I developed the 32-bit versions Beta 1 and Beta 2. Further information can be found on the official andLinux website: http://www.andlinux.org/
