*
* Rev 1.17 15 Apr 1996 16:57:28 RWolff
* Added definitions for various revisions of the GX and CX ASICs
*
* Rev 1.16 01 Mar 1996 12:09:48 RWolff
* VGA Graphics Index and Graphics Data are now handled as separate
* registers rather than as offsets into the block of VGA registers.
*
* Rev 1.15 22 Sep 1995 16:47:08 RWolff
* Added definitions for AL values of accelerator BIOS functions to
* allow switching on the low byte of the function.
*
* Rev 1.14 24 Aug 1995 15:41:12 RWolff
* Changed detection of block I/O cards to match Microsoft's
* standard for plug-and-play.
*
* Rev 1.13 24 Feb 1995 12:28:36 RWOLFF
* Added definitions used for relocatable I/O and 24BPP text banding
*
* Rev 1.12 20 Feb 1995 18:00:34 RWOLFF
* Added definition for GX rev. E ASIC.
*
* Rev 1.11 23 Dec 1994 10:48:02 ASHANMUG
* ALPHA/Chrontel-DAC
*
* Rev 1.10 18 Nov 1994 11:52:12 RWOLFF
* Register name change to CLOCK_CNTL to match latest documents, added
* some new bitfield definitions for registers.
*
* Rev 1.9 14 Sep 1994 15:20:58 RWOLFF
* Added definitions for all 32BPP colour orderings.
*
* Rev 1.8 31 Aug 1994 16:11:08 RWOLFF
* Removed VGA_SLEEP from enumeration of registers used on Mach 64
* (we don't access it, and it conflicts with DigiBoard), added
* support for BGRx in 32BPP (used by TVP3026 DAC).
*
* Rev 1.7 20 Jul 1994 12:59:38 RWOLFF
* Added support for multiple I/O base addresses for accelerator registers.
*
* Rev 1.6 12 May 1994 11:21:22 RWOLFF
* Added masks for pitch and pixel depth fields of ECX for BIOS_LOAD_CRTC
* call.
*
* Rev 1.5 05 May 1994 13:40:40 RWOLFF
* Added definitions for chip identification register fields.
*
* Rev 1.4 04 May 1994 10:58:48 RWOLFF

*
* Rev 1.3 27 Apr 1994 13:57:28 RWOLFF
* Added definitions for offsets of graphics index and graphics data
* registers from start of block of VGA registers.
*
* Rev 1.2 14 Mar 1994 16:31:58 RWOLFF
* Added offset and pitch masks for SRC_OFF_PITCH register.
*
* Rev 1.1 03 Mar 1994 12:36:40 ASHANMUG
* Correct GAMMA bit
*
* Rev 1.0 31 Jan 1994 11:26:34 RWOLFF
* Initial revision.
*
* Rev 1.4 24 Jan 1994 18:00:52 RWOLFF
* Added new definitions for fields introduced in 94/01/19 BIOS document.
*
* Rev 1.3 14 Jan 1994 15:17:18 RWOLFF
* Added definition for bit in GEN_TEST_CNTL to enable block write,
* BIOS function codes now take AH value from a single definition
* to allow single-point change of all codes, updated function codes
* to match BIOS version 0.13.
*
* Rev 1.2 30 Nov 1993 18:09:14 RWOLFF
* Fixed enumeration of register names, added definitions for more fields in
* more registers, removed redundant definitions.
*
* Rev 1.1 05 Nov 1993 13:21:24 RWOLFF
