Were there any operating systems or plain-boot utilities for the 8086-80186 era systems?

Basically, i'm making an emulator for XT/V20 kind of system, and the only software i can find are DOS, MS-DOS, another DOS and DOS programs.
Problem is, something too simple like boot sectors or my old 16bit OS works perfectly, while something slightly more complex hangs or crashes somewhere far and deep, but before any use.

So, 80186 diagnostic programs, alternative OS'es, bootsector games and demos, or something similar is what i'm looking for, and if you know where to look, please tell.

there should be a CP/M-86 - port of CP/M-80 to 8086 CPU

Minix 2.0.2 (16-bit) has support for 8086. (2.0.4 can run on 286, but that may be more of a RAM limit than actual cpu instruction compatibility.)

Also don't forget Linux/ELKS.

MikeOS, last I checked, was 16-bit too.

P.S. I know it's still technically DOS-related, but Win 3.0 [sic] could run on 8086.

Thank you both for info.

CP/M i did found, and it kinda works, but i have no idea what it should look like. Anyway, it exposes bugs and therefore useful.

Minix 2.0.2 boots up to "Executing in real mode", and then something hangs. Browsing the FM for the moment.

MikeOS uses 32bit instructions as early as the bootloader. not PC XT compatible.

ELKS is tricky... Some uncommon tar formats. still trying.

Win 3.0 needs DOS, DOS gives lots of excuses not to boot.


Found some booter games... Alley cat hangs in game, lode runner got timing errors in motion, frogger is to fast and exposes input bug. Fun never ends Smile

Artlav,

Sid Meyer's Pirates! (1987, CGA — IIRC) was bootable from 5.25" 360 KiB floppy.

I/O ERROR NR 45 in a blinking box with a saber-shaped cursor.
Whatever that means.

Out of the blue, PC-DOS 4 booted up, and things started rolling in an avalanche. Now every DOS from 1.1 up to 3.30 seems to boot up nicely.

Floppy controller bugs, keyboard bugs, CGA retrace stuck in sync with CPU (NC was redrawing panels bit by bit on every key press. spooky), floppy write support without destroying rest of the cylinder, NDD works, all 4 floppy drives in good health, format works, Zeliard works and playable, sunset.

x86 was a beautiful sight in it's infancy. That BIOS thing is amazing, an OS embedded in the PC, i quite forgot how useful it can be. All things making sense, whole system largely consistent, crutches hard to come by. Why couldn't they kept developing it in the same spirit, instead of the mess we ended up with? Damn compatibility.


Anyway, CheckIt 4 hangs on something called "CPU interrupt bug"... Something about NMI, it seems.
Anyone happen to have a description of that one, or a copy of the thing's manual?

You may add some diagnostic output (failed int13 service requests are primary suspects). I'll research later into this.

IIRC this test diagnose hlt not resuming execution after interrupt.

Maybe it's the floppy, and yet:

All seems well, no errors returned.

It appears to, the CPU is stuck on hlt with IF=0, which suggests something NMI-related to me.
No I/O ports activity prior, and if NMI is sent by a button, that's what it does:
