Is it possible to get these two cards working in the same computer? Both cards are PnP, but the amount of resources they demand would but a strain on any system.
Consider the SB AWE64:
Soundblaster Port
AWE Port
SB IRQ
Low DMA
High DMA
MPU401 Port
The GUS PnP is much worse
Ultrasound Port
Ultrasound IRQ
SB IRQ
Record DMA
Playback DMA
MPU401 Port
MPU401 IRQ
This does not include potential conflicts such as the joystick port, Adlib port. Also, the GUS PnP has an Atapi CD-ROM port, the AWE64 does not.
Here are the options I would use:
Soundblaster Port 220
AWE Port 620
SB IRQ 5
Low DMA 1
High DMA 5
MPU401 Port 330
Ultrasound Port 240
Ultrasound IRQ 7
SB IRQ 7
Record DMA 7
Playback DMA 7
MPU401 Port 332
MPU401 IRQ 7
In theory, it could work. For the Ultrasound, you will have to bear what appear to be IRQ and DMA conflicts. However, as we are gaming we only need one DMA for playback, no DMA is needed because we are not recording. The Ultrasound can take up three IRQs, but because we are not using SBOS, Mega-Em or IWSBOS, the SB and MPU IRQs are not going to be triggered. The Ultrasound is at 240, so it should not conflict with a Soundblaster at 220. The CD-ROM interface of the GUS can be disabled and its resources put in places where it can do no harm.
Now that is the theory, in practice things may be different getting these two cards to select these settings. Obviously one joystick interface will have to be disabled. You should also not use games that support Adlib through 388/389 because both cards will seek to do something with those reads and writes.
