Yes, sure; SES-2 is here (usual place, since it's a SCSI standard): http://www.t10.org/ftp/t10/drafts/ses2/ses2r19a.pdf SGPIO is more convoluted. The canonical link is http://www.sffcommittee.com/ but that just seems to send you back to seagate. The actual standard is this one: ftp://ftp.seagate.com/sff/SFF-8485.PDF James - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
