Well if you had the place, you simple could use 2 sound chips on the bord, 1 for windows and 1 for dos.
Maybe if the cpu got a sound onboard, or to use sound chip on the vodoo/vga card, if you don't have the space for it. Under windows it would not care if it's on a other bus than a ISA bus.

Been kinda busy these last days, but here's a quick update of my findings:
- The TL3.3 board looks alright, it does work (like the previous prototypes) and I can play games on it! 😀
- The MXM connector works with sdz's Voodoo4 card, I'm getting VGA and HDMI through MXM and out from the respective connectors on the TL board!
- My Mini-PCIe-to-MXM adapter works fine as well, tested with my SM750-based card.
- I think there's some kind of bug with my power circuit - It takes two pushes of the power button to turn on the board, one to power it down. I tried two different USB-C PD power bricks, identical result. Will investigate this further.
- My CM4 with eMMC works just fine even though the board also has an external SD card slot for the Pi. I guess that means you can use either the eMMC-equipped CM4 or the Lite version - I need to get one of those for testing.
- Haven't gotten to experimenting with the I2C IO expander and diagnostic LEDs yet.
- The SATA connector might not have been the best idea. I kinda forgot that SATA devices also require "SATA power", and there's obviously no ATX power supply with these power connectors at play here. What might be a much smoother solution is using an mSATA or M.2 connector. Problem is, there's no room currently on the board for such a connector. A good quality microSD card works very well though, so not sure it's worth pursuing really.
- I don't like the position of the power- and reset buttons. Will have to think long and hard about those, I do want them to be 90-degree ones, but they all have through-hole pins or stabilizer studs which would interfere with the MXM connector on the bottom side.
- My biggest concern right now, however, is PicoGUS's apparent lack of Win98 support. It works amazingly marvellous in DOS, but I'm really struggling getting either the GUS or SB mode working in Windows. Wish it had a WSS mode... 😁 Any and all suggestions are welcome!Edit: a little bird told me that a WSS mode might be in the cards...
