x86 - Downloading the CD image

Trying MINIX 3 is easy. You just download the compressed CD image file, decompress it, and burn it to a CD-ROM. This CD is a live CD. You can boot your computer from it and a few seconds later you log in as root. You do not have to install MINIX 3 to the hard disk to test it. If you decide you want to install it, you then have to create a hard disk partition for it (1GB to do anything useful) and start the live CD again and run setup. Proceed as follows:

  • Read the installation guide.
  • If you do not know how to partition a hard disk, print and read this short tutorial.
  • Development snapshots are available at the dev snapshots page.
  • Alternatively, download an official MINIX 3 distribution from the table below.

Decompressing the Image

The best known lossless compression algorithm is implemented in the bzip2 program. It also has extremely fast decompression. The popular 7zip archiver for Windows supports it too.

If you do not have the compression (bzip2) and decompression (bunzip2) software, here it is for Windows, Linux, and Solaris. Here is the source tarball. Bzip2 is also contained in the MINIX 3 distribution. The zip versions are provided as emergency backup in case you cannot get bzip2 running.
