These are root-install disk for AlphaSlack 8.3.1 for the Alpha.

CD installation
===============
You won't need to copy any of these images to floppy.  If you are booting
from a CD, all you'll need to know is that the ramdisk you want to use is
in /rootdsks/ramdisk.gz. Just go back and read the rest of the installation
directions - you don't need to do anything in this directory.

Here's a description of the disks:
-----------------------------------------------------------------------------
  ramdisk.gz  This image contains the AlphaSlack Installer.  It is designed
              to be used when booting from a CD.  If you plan on booting
              from CD, you don't need to copy this to a floppy; it won't
              fit!
