20376 is not currently supported. Promise do have their own GPL driver
which handles this device as if it were a scsi adapter. In the same way
that Jeff Garzik has realised we need to go this path for smart SATA 
stuff so have promise.

Figuring out what to do about all this for 2.4 is on my pending pile
still - do we merge a minimal support into base 2.4.x as FreeBSD did
with their support or do we merge a scsi layer driver that can actually
make use of the command queueing (not neccessarily tagged) on the device
and/or the hardware XOR engine.

I need to sit down with JG, AC, BZ, JA and work out a TF <> FIS lib for
First Party DMA.

I need to rip the SATA 1.0 out of drivers/ide/* and move it to a
scsi-sata.c,h and create a sas.c,h then generate a sata-sas-lib.c,h
solution.  Then abstract way the timings and setups to the scsi-template.

Obviously TCQ in FPDMA via direct FIS will map to SCSI with less pain.

I have FPDMA cores.

Cheers,

There is no GPL/LGPL support for the promise 20376 Fastrak 133
controller on Linux at the moment. There is a binary module from
Promise, but only on 2.4.18 i believe.

	http://www.promise.com/support/download/download2_eng.asp?productId=107&category=driver&os=100

I think someone is working on reverse engineering the code for
stock kernel inclusion.

I've got the same controller on my board, but no use for it
since i only have 2 disks on the machine which fit nicely on the
2 onboard IDE controllers in my A7V8X motherboard - though it'd
be nice to be able to buy and support ATA150 drive speeds.
