So enter at the command line:Īfter entering these two lines at the command prompt there is a quick test to see if the desired resources work by using a music player like XTC-PLAY with some music file. It checks for a GUS at the port address given in the environment variable ultrasnd and reads further the desired IRQ/DMA values and sets the card accordingly. To get the GUS configured the program ultrinit is run. It is a known bug that the GUS setup fails when checking for resources and reports problems specifically on DMA check. (Also some DOS4GW versions have a bug with hardware using DMA greater than 7).įor installation one can choose to run the whole GUS software setup 4.11 or just copy this ready setup folder. So a recommended setting is a jumpered base port of 240, IRQ 7 for playback and record and DMA 7 for record and playback. Typically a GUS is used in a system paired with a Sound Blaster. Usually for games and demos this is no limitation. The restriction is that it is no longer possible to record and play sound at the same time. But this can be reduced as the same IRQ and DMA can be set for playback and record. A GUS uses a IRQ and DMA for playback and another IRQ and DMA for recording. On the Gravis Ultrasound (GUS) the base port address has to be jumpered. The Gravis Ultrasound was released at a time when Creative had its Sound Blaster Pros on the market.
