Long time user, first time poster :)

So, I'd like to be able to run Minix 1.1 on my Macbook Pro mid-2012
w/16gb RAM (MacOS 10.14.6 Mojave). Qemu will run pretty ancient OS'es
such as DOS 2.0, which I use all of the time. However, I'm having some
difficulty getting Minix to run. I am able to boot the first floppy, but
when I change to the second floppy, the system freezes and I can't tell
what is going on. Here's what I did to get this far:

brew install qemu

qemu-system-i386 --version
QEMU emulator version 5.1.0

mkdir ~/workspaces/retro-workspace/minix-1.1
cd ~/workspaces/retro-workspace/minix-1.1
aria2c
http://download.minix3.org/previous-versions/bzipped/Intel-1.1.tar.bz2
tar xvjf Intel-1.1.tar.bz2
cp Intel-1.1/floppy_disk1 ./Disk01.img
cp Intel-1.1/floppy_disk2 ./Disk02.img
cp Intel-1.1/floppy_disk3 ./Disk03.img
cp Intel-1.1/floppy_disk4 ./Disk04.img


qemu-system-i386 -drive
file=Disk01.img,format=raw,if=floppy,media=disk,readonly=off,index=0,snapshot=on
\
  -boot a \
  -no-fd-bootchk \
  -monitor telnet::2222,server,nowait -serial mon:stdio

Qemu boots to the Minix 1.1 Boot screen and says to swap to floppy 2, so
in the monitor:
change floppy0 Disk02.img raw

I press l (el) and it scans the disk, lists the files on the disk and
reports no errors, but when I press =, it does a carriage return and
just sits there. I'm pretty sure this is the Minix going bye bye and not
necessarily QEMU, but I'm wondering if there is a way to see what QEMU
thinks it is doing or if it is what's hung? Usually, at this point,
Minix reads the disk contents into a Ramdisk and boots Minix.

Food for thought... Minix expects to run on an IBM PC (5150), IBM PC XT
(5160), or compatible, and therefore the I/O is written for whatever
floppy controller was extant at that time (I'm guessing here), so if
that's different than modern day floppies, I suppose this could cause
the problem I'm experiencing here. Is there a way to see the floppy
controller activity in QEMU? Similarly, I gather it expects a CGA
compatible monitor (EGA/VGA, etc should be fine).

Can you try adding '-machine isapc', which is closer to the 5150?


I appreciate your help on this.

Minix 1.1 works 'ok' in 86Box and other IBM PC emulations, so I know the
floppies are fine.

Thanks!

Will

    Phillipe,

      

      My new incantation is:

      

      qemu-system-i386 -machine isapc -drive
file=Disk01.img,format=raw,if=floppy,media=disk,readonly=off,index=0,snapshot=on  
      -boot a   -no-fd-bootchk   -monitor telnet::2222,server,nowait
      -serial mon:stdio

      

      with the same outcome :(. Thanks for the suggestion, I'll keep it
      in mind for other projects.

      

      Will
