Oh sorry, a quick google check told me PS/1 had 286. 386SX itself should be supported, the monochrome Toshiba on the photo has 386SX/20 with 10MB RAM.

Anyway, I tried the 16bit version, and it works like a charm!! Thank you. Here's a video of the boot, I've just made. https://www.youtube.com/watch?v=1fSsTa8Oc48

Although, the floppy light does not turn off. Not sure, if this a problem with the OS or my hardware.
