I have the command to send to the PMP controller but I am not an officianado with linux SATA(the code I have is from VxWorks) The drive is confirmed working, but the PMP chip does not default to SATA Generation 1, and this HDD is a bit dumb to figure it out :) - so I have to force the PMP controller to Gen1 mode.

linux/Documentation/kernel-parameters.txt:
