Yggdrasil – a Linux distribution developed by Yggdrasil Computing, Incorporated, a company founded by Adam J. Richter in Berkeley, California. Adam J. Richter started the Yggdrasil company together with Bill Selmeier. Yggdrasil was the first company to create a live CD Linux distribution. Yggdrasil Linux described itself as a “Plug-and-Play” Linux distribution, automatically configuring itself for the hardware.

Yggdrasil was a bootable Linux/GNU/X-based UNIX(R) clone for PC compatibles, tentatively named LGX. The system uses version 0.99.5 of the Linux kernel, which is being developed from scratch by Linus Torvalds and an international group of skilled contributors working over the internet to complete the GNU project.

The first relase was published in 1994 (an alpha in 1992) as a single CD, the second (and the last) release of Yggdrasil was in 1995 as 4 CD.

Here are some system requirements of Yggdrasil “Case 1993”:
– at least 386 CPU
– 4 MB RAM
– a supported CD-ROM drive
– ethernet card
– IDE or SCSI hard disk

Data of the distribution:
– Linux kernel 0.99.13 (released on September 20, 1993 as the first kernel with ELF support)
– size of the kernel image: 362 kbytes
– X-Window 11 release 5
– incl. TCP/IP and NFS
– software u.a. Andrew System version 5.1 (ez), Emacs, Ghostscript, Kermit, Z-Modem, Postgres 4.1, gcc
