Target Hardware Edit

    This project's goal is to turn the IO-Data Network Attached Storage device into an freely accessible Linux box. The device is available in several configurations:
  • Specification
    • Processor: SH4 266MHz(SH7751R)
    • Interface: 2 channels USB 2.0
    • Storage Capacity: HDD 160GB (HDL-160U), 250GB, 300GB, 400GB
    • Network Interface: 100BASE-TX/10BASE-T

    The device comes with a Linux 2.4 inside. There is the possibility to update to 2.6 and it is also possible to install Debian in a different partition. This gives you the choice at startup to either boot as original or as a Debian system. In case of booting Debian, you will not have the original functions, like user accounts, NAS, FTP, etc, but instead a lot of other functions as you can install the software packages.

Linux Kernel Edit

The original OS is linux-sh-2.4.21 . A new version linux-sh-2.6.22 is available from the linuxSH homepage.
The sourcecode for LANDISK target available here.

debian26 userland for SH4 Edit

  • What is debian26
    We are calling this userland debian26 in locals.
    • debian etch at Nov 2005
    • compiled by gcc-4.0.2
    • The linuxSH kernel 2.6 image is included.
    • Xorg-X11 with USB2VGAs Support for connecting VGA display.
    • About 1900 debian packages compiled for SH4 can be used.

How to setup debian26 Edit

  • Adding telnetd to the original system
    • IP address is set from the menu of LANDISK.(Password is "landisk").
    • A new user "landisk" is made from the menu of LANDISK.
    • Next, download from the web site "wizd on LANDISK". ( )
    • It is unzipped and update.tgz is retrieved.
    • Update the firmware by specifying update.tgz in the menu of LANDISK.
    • After reboot, you can telnet into the device:
      • Open a telnetsession, connect to the Landisk IP (port 23)
      • User account is landisk, password is "landisk".
      • To become root, "sudo su" is executed. (root password is "landisk")
      • To write it in rootfs, "mount -o rw,remount /" is executed.
  • Debian26 is constructed to /dev/hda3.
    • Install debian26 base system.
      # cd /mnt/hda3
      # tar vxfzp base26-sh4-xxxxxxxx-etch.tgz
      # mv debian26/* .
      # rm -rf debian26
    • Some files need to be corrected. (Following is an example based on my environment. The IP in red have to be changed according to your setup.)
      • /mnt/hda3/etc/hosts    localhost landisk
      • /mnt/hda3/etc/hostname
      • /mnt/hda3/etc/resolv.conf
        nameserver  ( <- this is your ISP's DNS server)
      • /mnt/hda3/etc/network/interfaces
        # Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
        # /usr/share/doc/ifupdown/examples for more information.
        auto lo
        iface lo inet loopback
        auto eth0
        iface eth0 inet static
  • /mnt/hda3/etc/hosts.allow
    ALL : 192.168.1. 192.168.0.
  • /mnt/hda3/etc/fstab
    #/dev/sda4     /            reiserfs    defaults        0 1
    /dev/sda3     /            ext2    defaults        0 0
    none          /proc        proc    defaults        0 0
    /dev/sda2     swap         swap    defaults        0 0
  • Setup boot-loader lilo-sh
    • copy some files from debian26(/dev/hda3) to /dev/hda1
      # mount -o rw,remount /
      # cp /mnt/hda3/boot/vmlinuz-2.6.22-landisk /boot
      # cp /mnt/hda3/boot/boot.b-selk /boot
  • /etc/lilo.conf - dual boot setting between original environment and debian26
            append="mem=64M console=ttySC1,9600 root=/dev/hda1"
            append="mem=64M console=ttySC1,9600 root=/dev/sda3"
  • Setup lilo
    # /mnt/hda3/sbin/lilo
