Special notes

  • For Acqua A5 with 512 MB of RAM rename boot512.bin in boot.bin in the first partition mounted on /boot
  • The image contains just the first two partitions (KERNEL and rootfs) and uses just the first 1.8 GB. To add more space create a third partition to add in /etc/fstab or enlarge the rootfs partition size with gparted.
