Ok, I built the floppy image now. dd'ed it on a floppy and powered my IBM PS/1 up. Despite some nasty sounds of the HDD bearings that went away after 30 seconds, the floppy does not boot on this machine. Just a black screen. 386SX-25 2MB RAM. Maybe 2MB RAM too less, but I thought at least something will happen. :-)
replyEven on 2MB, you should be able to at least see GRUB, which would tell you that it can't load the kernel. Does it go blank before that? This could mean an issue with either GRUB or the floppy.
replyThere seems to be an 8 meg image here: https://github.com/luke8086/gentleos32/releases/download/202...
replySomeone prepare a set of floppy disk images so you can get the proper installation experience.
replyIncluding the mandatory corruption on the last one.
replyThis is a hdd image, I guess.
replyI'm curious what model of PS/1? My first PC was a PS/1 model 2011, with a 286@10Mhz.
replyAlso, there's an emulator for PS/1 machines at https://www.ibmulator.org/
For PS/1 you'll need the 16-bit version from https://github.com/luke8086/gentleos. A floppy image is provided in releases. Note you only need to copy the first 64KB, the rest is just padding for emulators.
replyAh, 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.
