Folks...

I just checked in changes to the satalink(4) driver to support the 3114 
4-port SATA controller from Silicon Image.  The 3114 is basically an 
extension of the 2-port 3112 controller.  It supports master/slave 
emulation, but it also supports a more efficient 4-channel mode, which 
is how my code uses the device.  This mode allows all 4 channels to 
operate truly independent of one another, which means better 
performance.

Attached is an example of the boot messages you're likely to see with 
such a controller installed with 4 drives connected.

All you 3114 owners, consider this my Christmas present to you :-)

Cheers.
