I have a PCI sound card using the Yamaha YMF-724 chip. It can emulate a Sound Blaster Pro in Windows 9x through a DOS box or in real mode DOS.
The datasheet describes two ways to emulate the ISA resources in real mode DOS. First, there is the PC/PCI connector. Second, there is Distributed DMA. Not all motherboards have a PC/PCI (SB Link) connector, and newer motherboards do not support Distributed DMA. I am using an ASUS P3B-F, which uses the Intel i440BX chipset. This chipset supports Distributed DMA and some other ASUS motherboards (like the P2B-F), have a PC/PCI header.
In order to get the card working in DOS, you have to use Yamaha's DG-XG setup program from its DOS drivers. I am using version 3.16, the last version according to Yamaha. With the program, I can get the FM chip, joystick and the MPU-401 working, but not the digitized Sound Blaster Pro sound. It says that it cannot find a DMA channel and it refuses to let me change the emulation method from PC/PCI. According to this site:

The sound should work without a problem, and without EMM386. But I cannot seem to make it work. Can anyone help?
