Howdy folks. 😎 I'm banging my head here.

So I just got a FIC VA-503+ super socket 7 motherboard and I'm trying to configure my Sound Blaster (CT4170) on Win98 SE. The card installs just fine (220, IRQ 5 L-DMA1) but I noticed that dma 3 gets chosen as the second (high?) dma. By selecting manual config on the device manager I'm allowed only to choose channel 0, 1 and 3. No devices are using the high dma channels (5,6,7). On this board's BIOS I have the option to enable/dis PNP OS, manual configuration. I've tried messing around with these controls to no avail. The BIOS menu mentions all the DMA channels with options to set as reserved to PCI/ ISA PNP or Legacy ISA only. Am I missing something here? Are there "No High DMA" motherboards? Bios bug? The manual(s) is(are) accessible here:

Please help! Thanks in advance. 😀

One Linux sound FAQ suggests the CT4170 only has one DMA channel, and must be set the same otherwise it doesn't work properly

Interesting. I think I still have a CT2950 around here somewhere. I'll try swapping them tonight and hopefully the issue goes away.

Always ask old hardware questions in Marvin. This is DOS games on modern systems.

Forgot the reference ... http://www.faqs.org/docs/Linux-HOWTO/Sound-HOWTO.html#AEN882
Specifically mentions the CT4170

So I've swapped the CT4170 for a CT4500 and now I have the high dma channel set to 5. Weird. Does this happens with all the Vibras or is it just this card that gives this kind of headache? Anyway thanks for the info. Now I can play Duke Nukem. 😎

Sorry about that. I didn't notice that there was a hardware specific forum.
