Format of info structure:
Offset  Size    Description
00h    DWORD   pointer to VESA function dispatch table
04h    DWORD   pointer to SOLLEX function dispatch table
08h    DWORD   pointer to VESA SuperVGA info (see AX=4F00h)
0Ch    DWORD   pointer to mode info structure table, consisting of
alternating ResInfo (see below) and VESA mode information
(see AX=4F01h) blocks, terminated with an FFFFh word
10h    DWORD   pointer to font info structure table (see below)
14h    WORD    high resolution crystal frequency in Hz (0000h = not present)
16h    DWORD   pointer to ASCIZ ID string
1Ah    DWORD   pointer to timeout reset table
array of bytes, each a multiple of the minimum time increment
1Eh    WORD    minimum time increment in timer ticks
20h    BYTE    inverse options supported
bit 0: inverse supported
bits 1-7: reserved
21h    BYTE    normal color value
22h    BYTE    inverse color value
23h    WORD    port to be accessed for normal/inverse settings
25h    WORD    type of interface chip (currently undefined)
27h    WORD    program operational mode
bits 1-0: 00 no preference
01 terse (minimum detail in program messages)
10 verbose
11 use menus if supported, verbose mode otherwise
bits 7-2: reserved
29h    WORD    SOLLEX specification version
2Bh    WORD    version of VESA/SOLLEX implementation
2Dh    DWORD   offset to relocatable portion of SOLLEX extensions (for CONFIG)
2Eh    DWORD   offset to unused section of the extensions ROM
31h 16 BYTEs   reserved
Note:   all DWORD pointers initially require segment fixups; if the segment
is 0000h, it should be changed to the returned ES, otherwise it
may be assumed to be correct

04h    WORD    display info (see AX=7F01h/BL=01h)
06h    DWORD   pointer to video parameter table
0Ah    BYTE    replacement entry in master Video Parameter
0Bh    BYTE    mode requested for mode set by BIOS
0Ch    DWORD   pointer to LoadReg table
10h    BYTE    index into table of clock values (see below)

Format of font info table [array] entry:
Offset  Size    Description
