You might need VDMSound or DOSBox to run Arrakis in Windows 2000 since it seems that the sound is not turned off with /s command line.

Run ARRAKIS.BAT with VDMSound(right click on ARRAKIS.BAT and choose "Run with VDMSound"). Pick "set up a custom configuration" and in "Compatibility" menu increase the EMS memory to any above 8000 Kb and enable it.
