2 | * * | |
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 * | |
12 | * * | |
13 | * (c)1993-96 Michael Neuffer, Alfred Arnold * | |
14 | * neuffer@goofy.zdv.uni-mainz.de * | |
15 | * a.arnold@kfa-juelich.de * | |
16 | * * | |
17 | * Updated 2002 by Alan Cox <alan@redhat.com> for Linux * | |
18 | * 2.5.x and the newer locking and error handling * | |
