37	* The last 4096 bytes of the guest VRAM contains the generic info for all
38	* DualView chunks: sizes and offsets of chunks. This is filled by miniport.
39	*
40	* Last 4096 bytes of each chunk contain chunk specific data: framebuffer info,
41	* etc. This is used exclusively by the corresponding instance of a display driver.
42	*
43	* The VRAM layout:
44	* Last 4096 bytes - Adapter information area.
45	* 4096 bytes aligned miniport heap (value specified in the config rouded up).
46	* Slack - what left after dividing the VRAM.
47	* 4096 bytes aligned framebuffers:
48	* last 4096 bytes of each framebuffer is the display information area.
49	*
50	* The Virtual Graphics Adapter information in the guest VRAM is stored by the
51	* guest video driver using structures prepended by VBOXVIDEOINFOHDR.
52	*
53	* When the guest driver writes dword 0 to the VBE_DISPI_INDEX_VBOX_VIDEO
54	* the host starts to process the info. The first element at the start of
55	* the 4096 bytes region should be normally be a LINK that points to
56	* actual information chain. That way the guest driver can have some
57	* fixed layout of the information memory block and just rewrite
58	* the link to point to relevant memory chain.
59	*
60	* The processing stops at the END element.
61	*
62	* The host can access the memory only when the port IO is processed.
63	* All data that will be needed later must be copied from these 4096 bytes.
64	* But other VRAM can be used by host until the mode is disabled.
65	*
66	* The guest driver writes dword 0xffffffff to the VBE_DISPI_INDEX_VBOX_VIDEO
67	* to disable the mode.
68	*
69	* VBE_DISPI_INDEX_VBOX_VIDEO is used to read the configuration information
70	* from the host and issue commands to the host.
71	*
72	* The guest writes the VBE_DISPI_INDEX_VBOX_VIDEO index register, the the
73	* following operations with the VBE data register can be performed:
74	*
75	* Operation Result
76	* write 16 bit value NOP
77	* read 16 bit value count of monitors
78	* write 32 bit value sets the vbox command value and the command processed by the host
79	* read 32 bit value result of the last vbox command is returned
