|
|
*
|
|
* Rev 1.22 01 Mar 1996 12:10:48 RWolff
|
|
* Allocated more space for mapped registers, since VGA Graphics Index
|
|
* and Graphics Data are now handled as separate registers rather than
|
|
* as offsets into the block of VGA registers.
|
|
*
|
|
* Rev 1.21 02 Feb 1996 17:14:52 RWolff
|
|
* Moved DDC/VDIF merge source information into hardware device extension
|
|
* so each card can be considered independently in a multihead setup.
|
|
*
|
|
* Rev 1.20 29 Jan 1996 16:53:58 RWolff
|
|
* Now uses VideoPortInt10() rather than no-BIOS code on PPC, removed
|
|
* dead code.
|
|
*
|
|
* Rev 1.19 22 Dec 1995 14:52:32 RWolff
|
|
* Added support for Mach 64 GT internal DAC.
|
|
*
|
|
* Rev 1.18 19 Dec 1995 14:00:26 RWolff
|
|
* Increased size of buffer used to store query structure and mode tables
|
|
* to allow for increase in the number of "canned" tables due to support
|
|
* for higher refresh rates.
|
|
*
|
|
* Rev 1.17 28 Nov 1995 18:07:58 RWolff
|
|
* Added "Card Initialized" field to hardware device extension. This
|
|
* is part of multiheaded support, to prevent multiple initializations
|
|
* of a single card.
|
|
*
|
|
* Rev 1.16 27 Oct 1995 14:21:26 RWolff
|
|
* Removed mapped LFB from hardware device extension.
|
|
*
|
|
* Rev 1.15 08 Sep 1995 16:36:12 RWolff
|
|
* Added support for AT&T 408 DAC (STG1703 equivalent).
|
|
*
|
|
* Rev 1.14 24 Aug 1995 15:38:38 RWolff
|
|
* Changed detection of block I/O cards to match Microsoft's
|
|
* standard for plug-and-play.
|
|
*
|
|
* Rev 1.13 28 Jul 1995 14:39:50 RWolff
|
|
* Added support for the Mach 64 VT (CT equivalent with video overlay).
|
|
*
|
|
* Rev 1.12 31 Mar 1995 11:57:44 RWOLFF
|
|
* Changed debug thresholds to avoid being swamped by level 3 statements
|
|
* in VIDEOPRT.SYS, removed DEBUG_SWITCH since it's no longer used.
|
|
*
|
|
* Rev 1.11 30 Mar 1995 12:01:54 RWOLFF
|
|
* Added definitions for debug level thresholds.
|
|
*
|
|
* Rev 1.10 07 Feb 1995 18:19:54 RWOLFF
|
|
* Updated colour depth table for STG1702/1703. Entries for DACs
|
|
* that are supposedly equivalent to these are unchanged, since
|
|
* I did not have cards with these DACs and more than 2M of
|
|
* video memory to test with.
|
|
*
|
|
* Rev 1.9 30 Jan 1995 11:56:42 RWOLFF
|
|
* Added support for CT internal DAC.
|
|
*
|
|
* Rev 1.8 18 Jan 1995 15:39:32 RWOLFF
|
|
* Added support for Chrontel DAC.
|
|
*
|
|
* Rev 1.7 23 Dec 1994 10:48:32 ASHANMUG
|
|
* ALPHA/Chrontel-DAC
|
|
*
|
|
* Rev 1.6 18 Nov 1994 11:53:28 RWOLFF
|
|
* Added support for split rasters, Power PC, and new DAC type DAC_STG1703.
|
|
*
|
|
* Rev 1.5 06 Sep 1994 10:46:52 ASHANMUG
|
|
* Disable 1600x1200 on all cards except with TVM DAC
|
|
*
|
|
* Rev 1.4 31 Aug 1994 16:16:10 RWOLFF
|
|
* Added support for TVP3026 DAC and 1152x864, doubled QUERYSIZE to
|
|
* allow additional mode tables (needed because we now support 1152x864
|
|
* and 1600x1200, we have more refresh rates at 1280x1024, and TVP DAC
|
|
* supports high-res high depth modes AND 4BPP).
|
|
*
|
|
* Rev 1.3 19 Aug 1994 17:06:22 RWOLFF
|
|
* Added support for the SC15026 DAC.
|
|
*
|
|
* Rev 1.2 12 May 1994 11:09:00 RWOLFF
|
|
* Expanded CardInfo field of hardware device extension structure to allow
|
|
* more mode tables (needed when setting up "canned" refresh rates"), added
|
|
* defined value for hardware default refresh rate.
|
|
*
|
|
* Rev 1.1 03 Mar 1994 12:37:10 ASHANMUG
|
|
* Make pageable
