Disappointed that your modern PC doesn't have ISA?
Well - you've been lied to. Your motherboard does have an ISA bus, but it's locked away inside the chipset. And we can help it escape through the TPM connector.
I've designed an adapter that uses the Fintek F85226 LPC-to-ISA bridge to allow you to connect ISA cards to (theoretically) pretty much any motherboard, as long as it exposes the LPC bus somewhere and has a legacy BIOS or CSM.
And yes, DMA is fully functional!
Currently only works on baremetal DOS (probably linux too) but I'd love to see if a soundblaster driver could be written for Windows 11 😀
So far I've tried a Socket 755 motherboard with a Quad-core Xeon X5470, and a Socket 1155 motherboard with a 2nd gen Core i5, both work. The software should work on later Intel chipsets too, and may be portable to AMD. I wonder what the fastest possible DOS gaming PC is...

Source code and hardware design files will be open sourced ASAP. Hopefully together with SBEMU this will make baremetal DOS gaming cool again 😀
