I have two Dell 705N(4100) servers and need to upgrade SnapOS to 4.x, because I'm moving to 2003 domain and 3.x version is not supporting 2003 Domain.

So far from this topic I found this instructions:
-----------------
1) Go to the device's debug screen at http://{nas}/config/debug (using your own nas name or IP address of course, you'll be prompted for a login).
2) You'll then be prompted for debug commands, enter "bios unlock".
3) Now that the device is unlocked, enter command "bios oem none".
4) And then relock the device using "bios lock".
-----------------

Found couple posts from poogles_uk with ftp link to SnapOS to 4.x, but it's marked with ********.

Here is what I get from my system:
-----------------
PIC Version 1.0, Capibilities 0x00
Failsafe v2.4.437.FS Tue Aug 15 15:23:18 2000
Bios stamp 2.4.437 Tue Aug 15 15:23:15 2000
Plat Bytes 2.2.1
Model Byte 2
Flash failsafe sector not locked(30)

Product: 2 - "Laser/Spinnaker: 4 drive IDE" - Platform Bytes "2.2.1"
Server-3.4.790, Build Date: Mar 21 2002 20:16:10
This is the NON-Debug executable, and was built by KEVIN
-----------------

As far as I understand I need first v4.0.830 then the patch 4.0.860.

Please help!
