*** THIS IS NO LONGER SUPPORTED. DO NOT USE ***

CHARON-AXP supports emulation of an integrated virtual Acer Labs 1543C IDE/ATAPI controller.

By default the integrated virtual Acer Labs 1543C IDE/ATAPI controller is preloaded with a name "ide".

Example:

  • "/dev/sg<N>"

By default it is left unspecified.

(info) Read this article on how to find the physical device name for mapping.

Example:
set ide container="/dev/sg0" 

When running HP OpenVMS/Alpha Operating System on top of CHARON-AXP virtualization layer the specified CD/DVD-ROM drive is available as DQA0: device.
