1/*
2 * This file contains the driver for an XT hard disk controller
3 * (at least the DTC 5150X) for Linux.
4 *
5 * Author: Pat Mackinlay, pat@it.com.au
6 * Date: 29/09/92
7 *
8 * Revised: 01/01/93, ...
9 *
10 * Ref: DTC 5150X Controller Specification (thanks to Kevin Fowler,
11 * kevinf@agora.rain.com)
12 * Also thanks to: Salvador Abreu, Dave Thaler, Risto Kankkunen and
13 * Wim Van Dorst.
14 *
15 * Revised: 04/04/94 by Risto Kankkunen
16 * Moved the detection code from xd_init() to xd_geninit() as it needed
17 * interrupts enabled and Linus didn't want to enable them in that first
18 * phase. xd_geninit() is the place to do these kinds of things anyway,
19 * he says.
20 *
21 * Modularized: 04/10/96 by Todd Fries, tfries@umr.edu
22 *
23 * Revised: 13/12/97 by Andrzej Krzysztofowicz, ankry@mif.pg.gda.pl
24 * Fixed some problems with disk initialization and module initiation.
25 * Added support for manual geometry setting (except Seagate controllers)
26 * in form:
27 * xd_geo=<cyl_xda>,<head_xda>,<sec_xda>[,<cyl_xdb>,<head_xdb>,<sec_xdb>]
28 * Recovered DMA access. Abridged messages. Added support for DTC5051CX,
29 * WD1002-27X & XEBEC controllers. Driver uses now some jumper settings.
30 * Extended ioctl() support.
31 *
32 * Bugfix: 15/02/01, Paul G. - inform queue layer of tiny xd_maxsect.
33 *

75/* If you try this driver and find that your card is not detected by the driver at bootup, you need to add your BIOS
76 signature and details to the following list of signatures. A BIOS signature is a string embedded into the first
77 few bytes of your controller's on-board ROM BIOS. To find out what yours is, use something like MS-DOS's DEBUG
78 command. Run DEBUG, and then you can examine your BIOS signature with:
79
80 d xxxx:0000
81
82 where xxxx is the segment of your controller (like C800 or D000 or something). On the ASCII dump at the right, you should
83 be able to see a string mentioning the manufacturer's copyright etc. Add this string into the table below. The parameters
84 in the table are, in order:
85
86 offset ; this is the offset (in bytes) from the start of your ROM where the signature starts
87 signature ; this is the actual text of the signature
88 xd_?_init_controller ; this is the controller init routine used by your controller
89 xd_?_init_drive ; this is the drive init routine used by your controller
90
91 The controllers directly supported at the moment are: DTC 5150x, WD 1004A27X, ST11M/R and override. If your controller is
92 made by the same manufacturer as one of these, try using the same init routines as they do. If that doesn't work, your
93 best bet is to use the "override" routines. These routines use a "portable" method of getting the disk's geometry, and
94 may work with your card. If none of these seem to work, try sending me some email and I'll see what I can do <grin>.
95
96 NOTE: You can now specify your XT controller's parameters from the command line in the form xd=TYPE,IRQ,IO,DMA. The driver
97 should be able to detect your drive's geometry from this info. (eg: xd=0,5,0x320,3 is the "standard"). */
