Gravis Ultrasound Ace DMA problems

[robbo007]

Hi everyone,
I'm having problems getting my GUS ACE working on a 486 PC I acquired. I had it configured on my PII 400 under Windows 95 working perfectly. Now I'm trying under MSDOS 6.22 but can't seem to get a free DMA port. Each time I run the setup to configure the ports it says unsuccessful on all of the DMA ports that it can use. However if I try and configure a SB16 VIBRA card and use DMA 1 for example the sound blaster works fine. But alas the Ultrasound cannot use a DMA port. I'm using the latest drivers for the GUS ACE 4.11. I've removed everything out of the computer except the video card i/o card and the GUS ACE. Still the same.

Any ideas?

Try configuring the driver to a seemingly useable DMA port manually. IOW, edit the config.sys to what you want it to try and use. Try it with various ports.

This thread needs to be in the Later PCs one, but, is the parallel port set to ECP/EPP mode with DMA set to 3 or something thereof?

That did the trick. I found a website that talked about this same issue being a known problem with the setup.exe. I also had an older version of the software which didn't help. Once updated to 4.11 (latest version) and forcing the DMA to 7 via the setup and also in the autoexec.bat it works.

This will help us to understand the issue.
