Hi, I understand that 2.6.15 has the ATA Pass-Through support in libata. However, I'm getting back ILLEGAL REQUEST (INVALID COMAND OPERATION CODE) for both SCSI OPCODE's A1H and 85H. Is it because I don't have the right patch? How do I check to see if my kernel has this patch? Thanks in advance for you help. Best regards, Quat Le - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
