Updating ata controller firmware

cables [that were tied] in multiple knots to make sure it didn't break and the loss is acceptable" and "you can almost get two people pulling on it at once and it won't break the fibre".

They predicted that "Light Peak cables will be no more expensive than HDMI".

Thunderbolt controllers multiplex one or more individual data lanes from connected PCIe and Display Port devices for transmission via two duplex Thunderbolt lanes, then de-multiplex them for use by PCIe and Display Port devices on the other end.

A single Mini Display Port monitor or other device of any kind may be connected directly or at the very end of the chain.

Sumitomo Electric Industries started selling up to 30-metre-long (100-foot) optical Thunderbolt cables in Japan in January, 2013, Intel introduced Light Peak at the 2009 Intel Developer Forum (IDF), using a prototype Mac Pro logic board to run two 1080p video streams plus LAN and storage devices over a single 30-meter optical cable with modified USB ends.

On May 4, 2010, in Brussels, Intel demonstrated a laptop with a Light Peak connector, indicating that the technology had shrunk enough to fit inside such a device, and had the laptop send two simultaneous HD video streams down the connection, indicating that at least some fraction of the software/firmware stacks and protocols were functional.

The cable is actually a crossover cable, it swaps all receive and transmit lanes; e.g.Other implementations of the technology began in 2012, with desktop boards offering the interconnection now available.Apple said in February 2011 that the port was based on Mini Display Port, not USB.As the system was described, Intel's solution to the display connection problem became clear: Thunderbolt controllers multiplex data from existing DP systems with data from the PCIe port into a single cable.Older displays, using DP 1.1a or earlier, have to be located at the end of a Thunderbolt device chain, but native displays can be placed anywhere along the line. In that respect, Thunderbolt shares a relationship with the older system, which used the display connector to support a low-speed bus.
