Sample Dual Independent Head (DIH) Configuration

For DIH operation, several additional options must be set in the Device sections for each head. Both Device sections must specify the BusID, and the BusID must be the same for both devices. Each Device section must specify the Screen section that will associate the device with the Screen option.

BusID - B:F:S (Bus, Function, Slot)

Screen - number

The example below shows a sample DIH configuration. Only the Device, Screen, and Server Layout sections of the configuration file are shown.
