Boot Floppy (Digital UNIX systems)

To create a bootable floppy using Digital UNIX:

  1. Download the file mkbootarc.tar.

     You can untar mkbootarc on your target Digital UNIX system with the
     command:

     tar xvf mkbootarc.tar

	This file contains 2 .cmp images
		ab512.cmp for Alphastation 255 platforms
		arc445.cmp for Alphastation 200/250/400 series platforms

  2. Make sure you have a floppy that has been low-level formatted.

     For example, to low-level format a floppy in drive zero:

     fddisk -fmt /dev/rfd0a

  3. Run mkbootarc on the .cmp firmware image that you downloaded.

     mkbootarc uses a .cmp firmware image to create a file that can be dd'd
     to a floppy.

     The following will create a bootable floppy from a downloaded .exe
     firmware image:

     ./mkbootarc arc445.cmp | dd of=/dev/rfd0c bs=64k

     NOTE: This assumes the mkbootarc executable is in the current
     directory and that the floppy is in drive zero.

  4. Insert the floppy on the target system and boot it from the SRM
     console:

     >>> boot dva0
