Plan 9 Distribution


The Plan 9 distribution consists of two books, four 1.4 megabyte floppies, and a CD-ROM. The books contain the manual pages and a collection of papers describing the system. Click on the cover art to delve into the contents.

The four floppies contain a complete bootable Plan 9 system for IBM-compatible PCs (>=386). They have the kernel, the window system, Internet support, and programming environments for both the C and Alef languages. The CD-ROM contains everything: kernels, libraries, and utilities for the Intel 386 (including 486 and Pentium), Sparc, 68020, and Mips architectures and the sources to create them. It also has a selection of interesting stuff (road maps of the US, sky catalogs). Click on the CD-ROM art for a list of files on the CD-ROM; it's big.

To find out whether Plan 9 supports your hardware, read The Various Ports.

Free Trial

Plan 9 does not purport to run on all PCs. Since Plan 9 does not use the BIOS, it is sensitive to hardware differences between PCs. Therefore, we will provide the contents of the four floppies on the Internet via FTP for you to try out. Ftp to plan9.att.com, log in as anonymous, and get the files from /plan9/pcdist.
