Inital Release
==============


The firmware supports the release version of the Microsoft v3.0 SDK.  You need this, plus VS2008 with SP1 to develop applications using this firmware build. 

It includes basic driver support for all features on the TahoeII board, including PWM.

The default static IP address for this board is 192.168.1.123.  Use MFDeploy to update the network settings to match your network.  As with the v2.5 releases, we strongly recommend that you use a static IP address.  If you use DHCP, be aware that this process can take a long time on a slow network and the board will appear 'frozen' during during bootup while it is waiting for an address.

The firmware also includes SSL support.  To enable SSL support, you MUST connect to the board with MFDeploy and execute the Target->Manage Device Keys->Update SSL Seed function.
