Ah, even though the 386SX-25 is 32bit in my PS/1? Will try it eventually.
replyOh 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.
replyAnyway, I tried the 16bit version, and it works like a charm!! Thank you.
Here's a video of the boot, I've just made.

replyAlthough, the floppy light does not turn off. Not sure, if this a problem with the OS or my hardware.
Yes, the CPU is full 32-bits, but the bus in a 386 SX is only 16 bit. Those PS/1's are such a cool piece of computing history!
replyThe data bus was only 16 bits wide, but that doesn't really have much impact on OS compatibility; it just means that transferring a 32-bit value to or from memory takes two bus clock cycles instead of one. The address bus is only 24 bits wide, but that only affects physical memory address space; it still uses 32-bit pointers and a 32-bit virtual address space.
