* FUNCTION: cqd_ReportSummitVendorInfo
|
|
*
|
|
* PURPOSE: Determine the drive type of a summit drive.
|
|
*
|
|
* HISTORY:
|
|
* $Log: J:\se.vcs\driver\q117cd\src\0x1104e.c $
|
|
*
|
|
* Rev 1.7 23 Nov 1994 10:10:32 MARKMILL
|
|
* Set new device_descriptor structure element native_class to match the
|
|
* drive_class setting. This new data element is used to store the native
|
|
* class of the drive in the event of a "combo" drive (e.g. 3020/3010 drive).
|
|
*
|
|
*
|
|
* Rev 1.6 17 Feb 1994 11:36:40 KEVINKES
|
|
* Added an extra parameter to WaitCC and added support for QIC3010.
|
|
*
|
|
* Rev 1.5 18 Jan 1994 16:20:36 KEVINKES
|
|
* Updated debug code.
|
|
*
|
|
* Rev 1.4 13 Dec 1993 16:21:52 KEVINKES
|
|
* Cleaned up and commented.
|
|
*
|
|
* Rev 1.3 23 Nov 1993 18:50:04 KEVINKES
|
|
* Modified CHECKED_DUMP calls for debugging over the serial port.
|
|
*
|
|
* Rev 1.2 08 Nov 1993 14:06:46 KEVINKES
|
|
* Removed all bit-field structures, removed all enumerated types, changed
|
|
* all defines to uppercase, and removed all signed data types wherever
|
|
* possible.
|
|
*
|
|
* Rev 1.1 25 Oct 1993 16:21:10 KEVINKES
|
|
* Changed kdi_wt2ticks to kdi_wt004ms.
|
|
*
|
|
* Rev 1.0 18 Oct 1993 17:20:36 KEVINKES
|
|
* Initial Revision.
