* PURPOSE:
*
* HISTORY:
* $Log: J:\se.vcs\driver\q117cd\src\0x11017.c $
*
* Rev 1.8 15 May 1995 10:46:38 GaryKiwi
* Phoenix merge from CBW95s
*
* Rev 1.7.1.0 11 Apr 1995 18:03:18 garykiwi
* PHOENIX pass #1
*
* Rev 1.8 30 Jan 1995 14:24:46 BOBLEHMA
* Changed vendor to VENDOR_MOUNTAIN_SUMMIT.
*
* Rev 1.7 08 Dec 1994 11:34:30 BOBLEHMA
* Added a test for VENDOR_CMS on drive D. This is needed to find a CMS
* drive connected to a ZEOS with the Machete FDC. The new test is done
* after all others have failed.
*
* Rev 1.6 21 Oct 1994 16:02:58 BOBLEHMA
* Changed the search order. Look on drive D before drive B.
* #ifdef placed around code that selects the B drive. If testing doesn't
* produce an error, we can delete this code.
*
* Rev 1.5 18 Jan 1994 16:20:00 KEVINKES
* Updated debug code.
*
* Rev 1.4 13 Jan 1994 13:29:52 KEVINKES
* Modified the error mapping to allow the locate to succeed on
* all firmware errors.
*
* Rev 1.3 11 Jan 1994 14:22:22 KEVINKES
* Commented the code and added a filter for ERR_DRV_NOT_READY.
*
* Rev 1.2 23 Nov 1993 18:49:12 KEVINKES
* Modified CHECKED_DUMP calls for debugging over the serial port.
*
* Rev 1.1 08 Nov 1993 14:02:36 KEVINKES
* Removed all bit-field structures, removed all enumerated types, changed
* all defines to uppercase, and removed all signed data types wherever
* possible.
*
* Rev 1.0 18 Oct 1993 17:22:50 KEVINKES
* Initial Revision.

* The drive search must be done in a specific order. Drives which use only a
* hardware select scheme must be searched first. If they are not, some of
* them will simulate another manufacturers drive based on the SW select they
* receive. In many cases this simulation is incomplete and must not be used.
* Whenever possible, an attempt must be made to select a drive in it's native
* mode.
