From: Andrew Gabriel on 28 Jan 2007 08:46 I'm wondering what current state of SATA support on x86 is. I inserted a dual channel Silicon Image 3112A card into a system (not a RAID card, no BIOS on the card). Solaris sees it and recognises it as a disk controller, and creates two empty IDE device nodes on it in the device tree. Looking good I thought. However, it can't see any drives attached to the card. I get two console messages (presumably one for each port): ata_id_common: BUSY status 0xfe error 0x0 ata_id_common: BUSY status 0xfe error 0x0 Looking at the source, http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/io/dktp/controller/ata/ata_common.c#ata_id_common this is due to the ATA BUSY status bit not clearing after issuing the IDENTITY command to the disk. Is this due to some problem with my disks, or would I not expect the driver to work yet with native SATA controllers which don't have a BIOS to emulate an ATA interface? (I get same error if disks are connected or not.) My knowledge of ATA protocol predates the existance of SATA drives. -- Andrew Gabriel

Certainly there's no native SATA support for these (there for the Silicon Image Si3124/3132) Casper -- Expressed in this posting are my opinions. They are in no way related to opinions held by my employer, Sun Microsystems. Statements on Sun products included here are not gospel and may be fiction rather than truth.

In browsing around I see the RAID BIOS versions don't work with Solaris, and I've seen references to reflashing with the non-RAID BIOS to make those cards work. My card has no BIOS. -- Andrew Gabriel

Hi Everybody It was reported some time ago that the Sil0680 PATA worked as a consequence of Sun supporting the Silicon Image SATA card. Although the Sun web site implies it is ATA/IDE emulation. I have a RAID Sil0680 card and there is now an OpenSolaris bug Bug ID 6369927 Synopsis Provide method for enabling Silicon Image 0680 RAID controller as plain ATA controller. I receive replies about disabling the BIOS etc but Lunix Ubuntu supports the Sil 0680 (RAID as PATA) so I do not why sun can not address this issue.
