## Hardware Abstraction Layer (HAL)

Todo (Put here the generic, non-Matrox related, definition of a _hardware abstraction layer_ --[[JoseFonseca|JoseFonseca]]) 



---

 The HAL module is also a binary provided by Matrox to provide extra functionality with its XFree86 drivers for the G400/450/550 chips.  It provides support for dualhead and TV-out on G400 and DVI digital screen support on G450/550 cards.  It also allows you to use their MergedFB implementation for dualheaded cards and their powerdesk configuration utility. 

You can download it [[here|http://www.matrox.com/mga/support/drivers/latest/home.cfm]].  It's included with their Linux drivers.
