5 - Fix init mode (ah=00). Should use more BIOS variables
6 - Add new functionalities and modify static functionality table
7 - Performance : 16 bits IO
10 - Implement the remaining functions :
11 - chargen ax=1100, ax=1101, ax=1102, ax=1103, ax=1104, ax=1110,
12 ax=1111, ax=1112, ax=1120, ax=1121, ax=1122, ax=1123, ax=1124
15 - Reimplement the tables so it is compatible with the video save pointer table
16 - Implement the remaining functions (don't know if all are needed):
17 - set border ah=0b bh=00, set cga palette ah=0b bh=01,
18 - display switch interface ah=12 bl=35
19 - video refresh control ah=12 bl=36
20 - save/restore state ah=1c
24 - Implement the remaining functions :
25 - read/write graphic pixel ah=0c, ah=0d,
35 - upload the fonts to the "card" memory
36 - display fonts from the "card" memory (plex86/bochs vga card needs update)
38 =================================================================================================
42 - bugfixes for bochs 1.4(+) support
43 - implement remaining functions that can be done with DISPI 0xb0c0 interface
44 (get functions for mode?, window)
47 - extend DISPI interface (see also bochs bug [ 529554 ] unsupported VBE features DISPI update)
48 . clear / preserve display memory upon set vbe
49 . set/get logical scanline length (4f06)
50 . set/get display start (4f07)
51 - have plex86 host side display interface
52 - support more modi (16bit/32bit modi support)
53 - have text io functions in vbe mode
