-+ * This is the multiple IDE interface driver, as evolved from hd.c.
-+ * It supports up to MAX_HWIFS IDE interfaces, on one or more IRQs
-+ *   (usually 14 & 15).
-+ * There can be up to two drives per interface, as per the ATA-2 spec.
-+ *
-+ * Primary:    ide0, port 0x1f0; major=3;  hda is minor=0; hdb is minor=64
-+ * Secondary:  ide1, port 0x170; major=22; hdc is minor=0; hdd is minor=64
-+ * Tertiary:   ide2, port 0x???; major=33; hde is minor=0; hdf is minor=64
-+ * Quaternary: ide3, port 0x???; major=34; hdg is minor=0; hdh is minor=64
-+ * ...
-+ *
-+ *  From hd.c:
-+ *  |
-+ *  | It traverses the request-list, using interrupts to jump between functions.
-+ *  | As nearly all functions can be called within interrupts, we may not sleep.
-+ *  | Special care is recommended.  Have Fun!
-+ *  |
-+ *  | modified by Drew Eckhardt to check nr of hd's from the CMOS.
-+ *  |
-+ *  | Thanks to Branko Lankester, lankeste@fwi.uva.nl, who found a bug
-+ *  | in the early extended-partition checks and added DM partitions.
-+ *  |
-+ *  | Early work on error handling by Mika Liljeberg (liljeber@cs.Helsinki.FI).
-+ *  |
-+ *  | IRQ-unmask, drive-id, multiple-mode, support for ">16 heads",
-+ *  | and general streamlining by Mark Lord (mlord@pobox.com).

-+ *  October, 1994 -- Complete line-by-line overhaul for linux 1.1.x, by:
-+ *
-+ *	Mark Lord	(mlord@pobox.com)		(IDE Perf.Pkg)
-+ *	Delman Lee	(delman@ieee.org)		("Mr. atdisk2")
-+ *	Scott Snyder	(snyder@fnald0.fnal.gov)	(ATAPI IDE cd-rom)
-+ *
-+ *  This was a rewrite of just about everything from hd.c, though some original
-+ *  code is still sprinkled about.  Think of it as a major evolution, with
-+ *  inspiration from lots of linux users, esp.  hamish@zot.apana.org.au
-+ *
-+ *  Version 1.0 ALPHA	initial code, primary i/f working okay
-+ *  Version 1.3 BETA	dual i/f on shared irq tested & working!

-+ *			don't flush leftover data for ATAPI devices
-+ * Version 6.01		clear hwgroup->active while the hwgroup sleeps
-+ *			support HDIO_GETGEO for floppies
-+ * Version 6.02		fix ide_ack_intr() call
-+ *			check partition table on floppies

-+ *			  model based on suggestions from Russell King and
-+ *			  Geert Uytterhoeven

-+ *			Added idex=ata66 for the quirky chipsets that are
-+ *			  ATA-66 compliant, but have yet to determine a method
-+ *			  of verification of the 80c cable presence.
-+ *			  Specifically Promise's PDC20262 chipset.
-+ * Version 6.21		Fixing/Fixed SMP spinlock issue with insight from an old
-+ *			  hat that clarified original low level driver design.
