Hello, id like to share this source of an old dos multicore Demo.
https://pastebin.com/9sgW9dVu
and its assembler startu code
https://pastebin.com/3rG2eiWD
i found this on an old dvd that was part of company assignments. it seems to be a demo of multicore use in plain dos.
im not a programmerso i dont know where to post this the nerd way but it contained a binary and it at least does not crash and prints a heartbeat.
enjoy

Very interesting.
I wonder if sbemu/other quasi-emulators might find this useful...?

Lets hope it will be for someone. multi core use in Dos would be great feature...

Quick, buy up all the slot 1, 370 and socket A dual boards before someone figures out how to do Voodoo emulation on 2nd CPU. 🤣
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

I'm running an i3 with reasonable success in w98.
At 3ghz I probably don't really need to offload the sound, but I wouldn't say no to a virtual voodoo if it has the grunt.
That said, if picogus could magically become firmware of sorts that talks IRQs, io etc and to the hda, it might drag the "to new" curve up a few years.

I think RayeR talked about something similar somewhere. Or maybe i'm going crazy.
Edit: Comments say original by "bloodwych" They cannot be talking about bloodwych for DOS, right?
Edit 2: It's Bloodwych from the EAB (English Amiga Board)
Interesting stuff nonetheless. a worker core is running with no interrupt handlers, no page tables, no memory protection, and no OS. That's about as close to bare metal as you can get, meanwhile the other core is still running DOS. Fascinating.
