#          Minix3.4 on M1/M2 (ARM64)  Qemu HOWTO 
---------------------------------------------------------------

# Create a working directory to hold our files 

mkdir $HOME/minix3 
cd $HOME/minix3 

# Download the latest development snapshot (from 2017) 

wget http://download.minix3.org/iso/snapshot/minix_R3.4.0rc6-d5e4fc0.iso.bz2 
bunzip2 minix_R3.4.0rc6-d5e4fc0.iso.bz2 
mv minix_R3.4.0rc6-d5e4fc0.iso minix34.iso 

qemu-img create -f qcow2 disk.img 10G 

# Run this installer script 

qemu-system-i386 \
-m 256 \
-accel tcg \
-net nic,model=virtio \
-net user,hostfwd=tcp::2222-:22 \
-cdrom minix34.iso \
-hda disk.img \
-boot d 


# It takes some time to boot on the M2 MacBook Air so please be 
# patient it can take as long as 60 seconds or sometimes even more 

# Once it boots, login as root (no password) 
# And initiate the installation procedure by running setup 
# more info is available here https://wiki.minix3.org/doku.php?id=usersguide:doinginstallation#runningsetup 

setup 

#You can use the AUTO setup features and choose the default values, or customize 
# Network setup choose vio0  (1) 
# Autimaticaly using DHCP (IPv4 only) (2) 
# Quit 

# in the shell run to shut down the system 

shutdown -p now 

#Now we run the Minix3 with this script 

qemu-system-i386 \
-m 256 \
-accel tcg \
-net nic,model=virtio \
-net user,hostfwd=tcp::2222-:22 \
-cdrom minix34.iso \
-hda disk.img \
-boot c 

# Login as root (no password) 
# Setup a password for root 
# # More info https://wiki.minix3.org/doku.php?id=usersguide:postinstallation 

passwd 

# Create a local user 

useradd -m user 
usermod -G users,wheel user 

pkgin update
pkgin install openssh
cp /usr/pkg/etc/rc.d/sshd /etc/rc.d/
printf 'sshd=YES\n' >> /etc/rc.conf
/etc/rc.d/sshd start
 
# Then we can SSH to the Minix from our MacOS as follows (to enable X11 forwarding as well)  

ssh -XC -p 2222 user@localhost  




# X11 
-----

# Following xorg.conf works well on my M2 MacBook Air 
# Save it as /etc/X11/xorg.conf

# I dont like the default TWM so install fluxbox instead 

pkgin install fluxbox 

# then add this to your users $HOME/.xinitrc 

exec /usr/pkg/bin/startfluxbox 

# then you can run startx under your user to get a X11 desktop 
# modify $HOME/.fluxbox/menu accordingly to suite your needs
