* 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.
