VirtualAcorn Technical support:
Problems with Windows 8 and Windows 10 ATAPI drivers

This page is in the process of being updated so content may change.

RISC OS uses an old system called ATAPI (ATA Packet Interface) to connect to an optical drive (CD or DVD). Whilst this is an old standard it's still supported by almost all modern devices but the drivers in Windows 8 and Windows 10 can crash the VirtualRPC ATAPI component preventing the VirtualRPC from running. Currently the only fool proof way to bypass this problem is to remove the ATAPI component from VirtualRPC. This will mean that RISC OS won't be able to read CDs using CDFS, but there are a couple of workrounds which can solve the problem.

Modifying VirtualRPC to remove the ATAPI component

Once VirtualRPC is installed it's easy to remove the ATAPI component to bypass Windows ATAPI errors:

  • Using Windows explorer navigate to the VirtualRPC install folder:
  • C:\VirtualAcorn\VirtualRPC-xxx\
  • Make a new folder called PluginsDisabled.
  • Now open the folder Plugins.
  • Move the AtapiCD folder from Plugins to the PluginsDisabled folder.
  • Finally run VirtualRPC to confirm that the problem has been bypassed.

If you do need to remove the ATAPI component but must read some RISC OS format CDs (for example Artworks, DrawWorks, Ovation PRO etc) then this article explains how you can still read all Acorn format CDs without using CDFS.
