Creating the Installation Media
I will assume you purchased a legitmate copy of A/UX back in the early 1990's, and made a perfectly legal backup of the installation CD. You certainly did not download it from the internet... That would be illegal. Let's look at how to create a working A/UX 3.0.1 installation CD from your perfectly legal "backup" copy. Once you obtain a copy of AUX_3.0.1_Install.toast_image.gz, you need to decompress it using gzip. The image below shows how to decompress and verify the cdrom image.
The installation CD is a multi-partition disk, containing both Macintosh and Unix partitions. The AUX_3.0.1_Install.toast_image was created using Roxio Toast, but you can burn it with any decent burning software. I currently use cdrecord under Slackware Linux. No matter what software you use, do not use a re-writable disk!
The A/UX 3.0.1 installation CD is not bootable, so you will need an installation floppy. There are three floppy-images available in the downloads section: MacII Series, Quadra/Centris Series, and a custom installation disk. Pick an image, uncompress it, and write it to a floppy using the dd command in Unix/Linux:
