Fatdog64 Linux is a small yet versatile 64-bit multi-user Linux distribution. Originally created as a "fatter" (=more built-in applications) derivative of Puppy Linux, Fatdog has grown to become an independent, mature 64-bit Linux distribution while still keeping true to Puppy Linux spirit: small, fast and efficient.

At around 350MB, Fatdog boots up to a complete desktop environment ready for use. Most applications needed for everyday use is already included.

And many more included, with more in its package repositories.

Fatdog is versatile: Use is at a Live CD (or Live USB), or install it. Installation requires *no* re-partitioning. Fatdog can store its settings in your existing partition: FAT, Ext2/3/4, NTFS partitions are supported, as well as CIFS shares and LVM and mdadm partitions; on your harddisk, USB flash drive, or DVD+RW. PXE-booting Fatdog is easy - only two files are required.

Fatdog ISO is a dual-isohybrid ISO:

In either case, the resulting CD/DVD or USB flash drive will boot on standard systems, UEFI systems, and systems with Secure Boot enabled (Windows 8).
