Hi All, I recently bought an MSI K9A2 Platinum motherboard and it has a Promise PDC42819 SATA/SAS controller onboard. I haven't been able to get the controller to work with any of the libata sata drivers in mainline (although I did only try sata_promise, sata_sx4 or ahci; last two I was doubtful about but I figured it was worth a try). Has anyone played with this controller under Linux before and can it be made to work with any of the open source drivers - I would realy like to use the eSATA and internal SATA ports attached to this controller (and I don't want to trust my data to the promise binary blob)? Maybe it's as simple as adding the right PCI ID to sata_promise, but I wasn't sure what kind of board it should be: 2037x, 2057x, 20319, 40518, 20619, or maybe some new one... I'm not sure how important this is but I gathered the following info about the controller: References to the controller in the motherboard manual and the motherboard manufacturer's website: Promise T3 [1] Written on the actual chip on the motherboard: Promise PDC42819 [2] This chip is also used on Promise's own FastTrak TX2650 & TX4650 adapters [3] which have "partial open source" drivers [4], [5]. This driver looks like an open source wrapper around a binary blob (some fasttrak library for software fake raid, I think). Having a quick look through the source of Promise's driver, it looks like the driver has been hacked up out of a driver that was originally used for fakeraid on ATI and intel southbridges as well as Promise's SX4 adapter (and some Promise adapter called the OCTOPUSII). Promise has an open source commitment written on its werbsite [6] but it just relates to their SuperTrak products (not their FastTrak ones) and the stex driver. The following is the hunk of lspci output that refers to the controller: 02:00.0 RAID bus controller [0104]: Promise Technology, Inc.
