|
|
* New driver sources
|
|
*
|
|
* Rev 1.16 23 Jan 1996 11:41:36 RWolff
|
|
* Now forces compile-time error if NTDDVDEO.H is not included before
|
|
* this file rather than generating false values of TARGET_BUILD, added
|
|
* DrvEscape() functions used by multiheaded display applet.
|
|
*
|
|
* Rev 1.15 22 Dec 1995 14:59:32 RWolff

|
|
*
|
|
* Rev 1.14 21 Dec 1995 14:05:36 RWolff
|
|
* Added TARGET_BUILD definition to identify which version of NT we are
|
|
* building for, rather than using a different definition for each break
|
|
* between versions.

|
*
|
|
* Rev 1.13 23 Nov 1995 11:25:10 RWolff

|
* TVP3026 cursor handling is needed.
|
|
*
|
|
* Rev 1.5 04 May 1994 19:24:04 RWOLFF
|
|
* Moved block write flag back to IOCTL_VIDEO_ATI_GET_MODE_INFORMATION

|
|
* into graphics mode.
|
|
*
|
|
* Rev 1.4 28 Apr 1994 10:58:52 RWOLFF
