Abstract:
|
||
|
||
This module contains the definitions for the code that implements the
|
||
Compaq QVision VGA device driver.

Revision History:
|
||
|
||
$0003
|
||
miked: 12/14/1993
|
||
Added ioctl CPQ_IOCTL_VIDEO_INFO to give asic info and more
|
||
back to the hardware accelerated port driver. Also added min macro.
|
||
Added #include of qry_nt.h to get access to structure
|
||
VIDEO_CHIP_INFO (added to device extension).
