====== LaCie operating systems ======

This section gathers all informations about the different LaCie stock systems.

===== Legacy system (before 2011-2012) =====

==== EEPROM ====

=== Organization ===

The EEPROM is available for reading and writing under Linux at the pseudo file **/sys/bus/i2c/devices/0-0050/eeprom**.
The content of the eeprom is the following:

^Offset ^Meaning               ^Notes ^
|00..01 |Version/MAC Addresses |It indicates how many mac addresses are stored in the eeprom, it's always 00 02 (2) but only the first mac appears to be valid |
|02..07 |Mac address           |It's the mac address of your board |
|08..13 |2nd Mac address       |Bogus mac address 01 FF FF FF FF FF |
|14     |Power flag            |0 = wait for the button, 1 = auto power on |
|15     |Fake sleepmode        |Used by the Lacie stock initramfs, it's FD and you can ignore it |

=== Auto power on ===

Normally, after applying power, you have to push the button to turn on the ns2. If you want it to switch on automatically, you have to switch a bit in the i2c eeprom.
The bit is at offset 14 in the eeprom, changing it from 0 to 1 will enable auto switch on.

==== Disk partitions ====

  * sda1: extended, 2056 Mb
  * sda2: xfs, md raid0/raid1, user data, the remaining part of the disk
  * sda5: swap, md raid1, 263,18 Mb
  * sda6: Linux kernel U-Boot Image, 8,23 Mb
  * sda7: ext3, md raid1, minimal root partition, 8,23 Mb
  * sda8: ext3, md raid1, original firmware partition, 871,88 Mb
  * sda9: ext3, md raid1, snapshots/upgrades partition, 896,56 Mb
  * sda10: filled with zeroes (may be used for an alternate kernel), 8,23 Mb

=== Boot ===

The Linux kernel is loaded from disk.

==== Linux ====

Here are the possible versions for the Linux kernel:
  * 2.6.22.18.
  * 2.6.31.14.

Here are the possible versions for the Linux Marvell patch:
  * LSP 5.0.3
  * LSP 5.1.3

==== Userland ====

  * Coreutils: busybox
  * HTTP: lighttpd
  * FTP: ProFTPd
  * SMB: Samba (unix extensions disabled by default; to enable them, change the corresponding line in /snaps/00/etc/samba/smb.conf on sda9)
  * Bonjour: Avahi/Zeroconf
  * SSH: Openssh (disabled by default; to enable it, uncomment the corresponding line in /etc/initng/runlevel/default.runlevel on sda8 and change root password in /snaps/00/etc/shadow on sda9)
  * Rsync: disabled by default, to enable it define a new daemon in /etc/initng on sda9 to launch "/usr/bin/rsync --daemon" and add it to /etc/initng/runlevel/default.runlevel
  * Deep sleep mode: can be enabled from the web interface, but if ssh has been enabled it is simpler to call /sbin/smart_shutdown
