Bela VS SBEMU

Bela looks interesting to me. Low latency audio on the BeagleBone platform via it's embedded PRUs.

What about FreeDOS?

FreeDOS with SBEmu is really nice for an instant DOS machine on real hardware:

SBEMU is a game changer. You can now have sound-blaster support through emulation. It's not perfect but works surprisingly well (https://github.com/crazii/SBEMU)

DOS emulation is not a very battery-efficient way to play '88-98 games on the go, so projects like these seem to cater to that specific need, letting people run DOS natively. The Toshiba Libretto was a nice, small machine, but finding one in good condition is super hard. Toshiba Portégé was another, but after Pentium-II models, they took away the OPL3 card in favor of something more Windows-friendly (AC97), which doesn't have good DOS drivers. Now there's SBEMU (https://github.com/crazii/SBEMU), which can emulate SB/SBPRO/SB16 on top of newer PCI-based sound cards, including AC97 ones, solving that problem. Now it's possible to have sound on a Pentium-II, III, M and Atom machines running DOS, like a Sony Vaio P.

I am not familiar with the sound chip inside this laptop, but i recently discovered SBEMU, it may not be relevant, but it offers another soundblaster emulation option (for the correct hardware).
