=====PC Engines ALIX.2d13 - Debian buster=====

====Connect and configure BIOS====
  * Get the board out of the case, for access to the CF card.
  * Connect a serial console, power up and boot the board.
  * Enter the BIOS settings, by pressing 's'.
  * Set the console baud rate to 115200.
  * Exit and save the settings.

====Prepare the CompactFlash card====
  * Remove the card out of the board, and connect it to your host machine.
  * Partition the CF card:<code>
# Make sure you've got the the right blockdevice here.
CFDRIVE=/dev/sdc

# Unmount partitions if they are automounted.
umount ${CFDRIVE}{1,2}

# Remove partition table
dd if=/dev/zero of=${CFDRIVE} bs=512 count=1 conv=notrunc

# Make a new partion table for /boot and the / root filesystem.
parted --script $CFDRIVE              \
    mklabel msdos                     \
    unit mib                          \
    mkpart primary ext4 1MiB 500MiB   \
    toggle 1 boot                     \
    mkpart primary ext4 500MiB 100%

# Create the filesystems
mkfs.ext4 -L boot ${CFDRIVE}1
mkfs.ext4 -L root ${CFDRIVE}2

# Mount the filesystems
mount ${CFDRIVE}2 /mnt
mkdir /mnt/boot
mount ${CFDRIVE}1 /mnt/boot</code>

====Install Debian Buster====
  * Install Debian Buster with debootstrap:<code>debootstrap --verbose --arch i386 buster /mnt http://ftp.nl.debian.org/debian</code>

====Enter the chroot====
  * Bind mount some special filesystems and enter the chroot:<code>
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
mount --bind /dev /mnt/dev

LANG=C linux32 chroot /mnt /bin/bash</code>

====Configure Debian Buster====

  * Still in the chroot:<code>

# Configure /etc/fstab
cat > /etc/fstab <<EOF
# file system    mount point   type    options                      dump pass
/dev/sda2         /             ext4    noatime,noatime,commit=120   0    1
/dev/sda1         /boot         ext4    ro,nosuid,nodev              0    2
EOF

# Configure apt
cat > /etc/apt/sources.list <<EOF

# Install needed packages
apt install linux-image-686 grub-pc dnsutils ssh vim dialog locales 

# Install grub, change the blockdevice to your own
grub-install --boot-directory=/boot --modules=part_msdos /dev/sd?

# Modify GRUB settings (for serial console) in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8"

# Generate a new GRUB config
grub-mkconfig -o /boot/grub/grub.cfg

# Add user and set passwords for user and root
useradd -d /home/user -m -s /bin/bash user
passwd user
passwd root

# Set hostname
echo alix2d13 > /etc/hostname
echo "127.0.0.1 alix2d13" >>/etc/hosts

# Configure the first network interface (as DHCP client)
cat > /etc/systemd/network/enp0s9.network <<EOF

EOF

# Exit the chroot and unmount filesystems
exit
umount /mnt/sys
umount /mnt/dev
umount /mnt/dev/pts
umount /mnt/proc
umount /mnt/boot
umount /mnt
sync</code>

====Boot the alix2d13 board====
{{:img_1880.jpg?nolink&400|}}

  * Insert the CF card in the board and power it up.
  * Log in as root and enable networking:<code>
systemctl start systemd-resolved
systemctl enable systemd-resolved

systemctl start systemd-networkd
systemctl enable systemd-networkd</code>
  * Set the timezone:<code>timedatectl set-timezone Europe/Amsterdam</code>
  * Configure locales<code>dpkg-reconfigure locales</code>

====LED's====
The LED's are supported out of the box.

  * Install sysfsutils:<code>apt install sysfsutils</code>
  * Add to /etc/sysfs.conf:<code>
devices/platform/leds-gpio/leds/alix:1/brightness = 1
devices/platform/leds-gpio/leds/alix:2/trigger = disk-activity
</code>
  * Restart sysfsutils (or reboot) to test:<code>systemctl restart sysfsutils</code>
