3 * Linux EATA SCSI PIO driver *
4 * *
5 * based on the CAM document CAM/89-004 rev. 2.0c, *
6 * DPT's driver kit, some internal documents and source, *
7 * and several other Linux scsi drivers and kernel docs. *
8 * *
9 * The driver currently: *
10 * -supports all EATA-PIO boards *
11 * -only supports DASD devices *

Alan Coxfa195af2008-10-27 15:16:36 +000017 * Updated 2002 by Alan Cox <alan@lxorguk.ukuu.org.uk> for *
18 * Linux 2.5.x and the newer locking and error handling *
