ABSTRACT - -This text gives a fairly basic, yet technical, explanation to what, why -and how Mode X is. It first tries to explain the layout of the VGA -memory and the shortcomings of the standard 320x200 256-color mode, -then gives instructions on how one can progress from mode 13h to a -multipage, planar 320x200 256-color mode, and from there to the -quasi-standard 320x240 mode, known as Mode X. - -A little experience in programming the standard VGA mode 13h -(320x200 in 256 colors) is assumed. Likewise a good understanding of -hexadecimal notation and the concepts of segments and I/O ports is -assumed. Keep a VGA reference handy, which at least should have -definitions of the VGA registers at bit level. - -Throughout the article, a simple graphics library for unchained (planar) -256-color modes is developed. The library supports the 320x200 and -320x240 modes, active and visible pages, and writing and reading -individual pixels. - - -1. INTRODUCTION TO THE VGA AND ITS 256-COLOR MODE - -Since its first appearance on the motherboards of the IBM PS/2 50, 60 -and 80 models in 1987, the Video Graphics Array has been the de facto -standard piece of graphics hardware for IBM and compatible personal -computers. The abbreviation, VGA, was to most people synonymous with -acceptable resolution (640x480 pixels), and a stunning rainbow of colors -(256 from a palette of 262,144), at least compared to the rather gory -CGA and EGA cards. - -Sadly, to use 256 colors, the VGA BIOS limited the users to 320x200 -pixels, i.e. the well-known mode 13h. This mode has one good and one -bad asset. The good one is that each one of the 64,000 pixels is easily -addressable in the 64 Kb video memory segment at 0A000h. Simply calculate -the offset using this formula: - -offset = (y * 320) + x; - -Set the byte at this address (0A000h:offset) to the color you want, and -the pixel is there. Reading a pixel is just as simple: just read the -corresponding byte. This was heaven, compared to the havoc of planes and -masking registers needed in 16-color modes. Suddenly, the distance from a -graphics algorithm on paper to an implemented graphics routine in assembly -was cut down to a fraction. The results were impressively fast, too! - -The bad asset is that mode 13h is also limited to only one page, i.e. -the VGA can hold only one screenful at any one time (plus 1536 pixels, or -about four lines). Most 16-color modes let the VGA hold more than one page, -and this enables you to show one of the pages to the user, while drawing on -another page in the meantime. Page flipping is an important concept in making -flicker free animations. Nice looking and smooth scrolling is also almost -impossible in mode 13h using plain VGA hardware. - -Now, the alert reader might say: "Hold on a minute! If mode 13h enables -only one page, this means that there is memory for only one page. But I -know for a fact that all VGAs have at least 256 Kb RAM, and one 320x200 -256-color page should consume only 320*200=64000 bytes, which is less -than 64 Kb. A standard VGA should room a little more than four 320x200 -pages!" Quite correct, and to see how the BIOS puts this limitation on -mode 13h, I'll elaborate a little on the memory organization of the VGA. - -The memory is separated into four bit planes. The reason for this stems -from the EGA, where graphics modes were 16-color. Using bit planes, the -designers chose to let each pixel on screen be addressable by a single -bit in a single byte in the video segment. Assuming the palette has -not been modified from the default, each plane represent one of the EGA -primary colors: red, green, blue and intensity. When modifying the bit -representing a pixel, the Write Plane Enable register is set to the -wanted color. Reading is more complex and slower, since you can -only read from a single plane at a time, by setting the Read Plane -Select register. Now, since each address in the video segment can -access 8 pixels, and there are 64 Kb addresses, 8 * 65,536 = 524,288 -16-color pixels can be accessed. In a 320x200 16-color mode, this makes -for about 8 (524,288/(320*200)) pages, in 640x480 you get nearly 2 -(524,288/(640*480)) pages. - -In a 256-color mode, the picture changes subtly. The designers decided -to fix the number of bit planes to 4, so extending the logic above to 8 -planes and 256 colors does not work. Instead, one of their goals was to -make the 256-color mode as easily accessible as possible. Comparing the -8 pixels/address in 16-color modes to the 1-to-1 correspondence of -pixels and addresses of mode 13h, one can say that they have -succeeded, but at a certain cost. For reasons I am not aware of, the -designers came up with the following effective, but memory-wasting -scheme: - -The address space of mode 13h is divided evenly across the four bit -planes. When an 8-bit color value is written to a 16-bit address in the -VGA segment, a bit plane is automatically selected by the 2 least -significant bits of the address. Then all 8 bits of the data is written -to the byte at the 16-bit address in the selected bitplane (have a look at -figure 1). Reading works exactly the same way. Since the bit planes are so -closely tied to the address, only every fourth byte in the video memory is -accessible, and 192 Kb of a 256 Kb VGA go to waste. Eliminating the -need to bother about planes sure is convenient and beneficial, but to -most people the loss of 3/4 of the total VGA memory sounds just hilarious. - -To accomodate this new method of accessing video memory, the VGA -designers introduced a new configuration bit called Chain-4, which -resides as bit number 3 in index 4 of the Sequencer. In 16-color modes, -the default state for this bit is off (zero), and the VGA operates as -described earlier. In the VGA's standard 256-color mode, mode 13h, this -bit is turned on (set to one), and this turns the tieing of bit -planes and memory address on. - -In this state, the bit planes are said to be chained together, thus mode -13h is often called a _chained mode_. - -Note that Chain-4 in itself is not enough to set a 256-color mode - -there are other registers which deals with the other subtle changes in -nature from 16 to 256 colors. But, as we now will base our work with -mode X on mode 13h, which already is 256-color, we won't bother about -these for now. - - - -2. GETTING MORE PAGES AND PUTTING YOUR FIRST PIXEL - -The observant reader might at this time suggest that clearing the -Chain-4 bit after setting mode 13h will give us access to all 256 Kb of -video memory, as the two least significant bits of the byte address -won't be `wasted' on selecting a bit plane. This is correct. You might -also start feeling a little uneasy, because something tells you that -you'll instantly loose the simple addressing scheme of mode 13h. Sadly, -that is also correct. - -At the moment Chain-4 is cleared, each byte offset addresses *four* -sequential pixels, corresponding to the four planes addressed in 16-color -modes. Every fourth pixel belong in the same plane. Before writing to a byte -offset in the video segment, you should make sure that the 4-bit mask in the -Write Plane Enable register is set correctly, according to which of the four -addressable pixels you want to modify. In essence, it works like a 16-color -mode with a twist. See figure 2. - -So, is this mode X? Not quite. We need to elaborate to the VGA how to -fetch data for refreshing the monitor image. Explaining the logic -behind this is beyond the scope of this getting-you-started text, and it -wouldn't be very interesting anyway. Also, mode 13h has only 200 lines, -while I promised 240 lines. I'll fix that later below. Here is the minimum -snippet of code to initiate the 4 page variant of mode 13h (320x200), written -in plain C, using some DOS specific features (see header for a note about the -sources included): - -----8<-------cut begin------ - -/* width and height should specify the mode dimensions. widthBytes - specify the width of a line in addressable bytes. */ - -int width, height, widthBytes; - -/* actStart specifies the start of the page being accessed by - drawing operations. visStart specifies the contents of the Screen - Start register, i.e. the start of the visible page */ - -unsigned actStart, visStart; - -/* - * set320x200x256_X() - * sets mode 13h, then turns it into an unchained (planar), 4-page - * 320x200x256 mode. - */ - -set320x200x256_X() - { - - union REGS r; - - /* Set VGA BIOS mode 13h: */ - - r.x.ax = 0x0013; - int86(0x10, &r, &r); - - /* Turn off the Chain-4 bit (bit 3 at index 4, port 0x3c4): */ - - outport(SEQU_ADDR, 0x0604); - - /* Turn off word mode, by setting the Mode Control register - of the CRT Controller (index 0x17, port 0x3d4): */ - - outport(CRTC_ADDR, 0xE317); - - /* Turn off doubleword mode, by setting the Underline Location - register (index 0x14, port 0x3d4): */ - - outport(CRTC_ADDR, 0x0014); - - /* Clear entire video memory, by selecting all four planes, then - writing 0 to the entire segment. */ - - outport(SEQU_ADDR, 0x0F02); - memset(vga+1, 0, 0xffff); /* stupid size_t exactly 1 too small */ - vga[0] = 0; - - /* Update the global variables to reflect the dimensions of this - mode. This is needed by most future drawing operations. */ - - width = 320; - height = 200; - - /* Each byte addresses four pixels, so the width of a scan line - in *bytes* is one fourth of the number of pixels on a line. */ - - widthBytes = width / 4; - - /* By default we want screen refreshing and drawing operations - to be based at offset 0 in the video segment. */ - - actStart = visStart = 0; - - } - -----8<-------cut end------ - -As you can see, I've already provided some of the mechanics needed to -support multiple pages, by providing the actStart and visStart variables. -Selecting pages can be done in one of two contexts: - - 1) selecting the visible page, i.e. which page is visible on - screen, and - - 2) selecting the active page, i.e. which page is accessed by - drawing operations - -Selecting the active page is just a matter of offsetting our graphics -operations by the address of the start of the page, as demonstrated in -the put pixel routine below. Selecting the visual page must be passed -in to the VGA, by setting the Screen Start register. Sadly enough, the -resolution of this register is limited to one addressable byte, which -means four pixels in unchained 256-color modes. Some further trickery is -needed for 1-pixel smooth, horizontal scrolling, but I'll make that a subject -for later. The setXXXStart() functions provided here accept byte -offsets as parameters, so they'll work in any mode. If widthBytes and -height are set correctly, so will the setXXXPage() functions. - -----8<-------cut begin------ - -/* - * setActiveStart() tells our graphics operations which address in video - * memory should be considered the top left corner. - */ - -setActiveStart(unsigned offset) - { - actStart = offset; - } - -/* - * setVisibleStart() tells the VGA from which byte to fetch the first - * pixel when starting refresh at the top of the screen.

Here's a put pixel routine -for any unchained 256-color mode (it assumes that the 'width' variable -from the above code is set correctly). Optimizing is left as an exercise -to you, the reader. This will be the only drawing operation I'll cover -in this article, but all general primitives like lines and circles can be -based on this routine. (You'll probably not want to do that though, due -to the inefficiency.) - -----8<-------cut begin------ - -putPixel_X(int x, int y, char color) - { - - /* Each address accesses four neighboring pixels, so set - Write Plane Enable according to which pixel we want - to modify.

You can enable any combination of all -four to be written. This ability to access 4 pixels with one -instruction helps quadrupling the speed in certain respects, especially when -drawing horizontal lines and filling polygons of a constant color. Also, most -block algorithms can be optimized in various ways so that they need only -a constant number of OUTs (typically four) to the Write Plane Enable -register. OUT is a relatively slow instruction. - -The gained ability to access the full 256 Kb of memory on a standard -VGA enables you to do paging and all the goodies following from that: -smooth scrolling over large maps, page flipping for flicker free -animation... and I'll leave something for your own imagination. - -In short, the stuff gained from unchaining mode 13h more than -upweighs the additional complexity of using a planar mode. - -Now, the resolution of the mode is of little interest in this -context. Nearly any 256-color resolution from (about) 80x8 to 400x300 -is available for most VGAs. I'll dwell particularly by 320x240, as this -is the mode that Michael Abrash introduced as 'Mode X' in his DDJ -articles. It is also the resolution that most people refer to when -using that phrase. - -The good thing about the 320x240 mode is that the aspect ratio is -1:1, which means that each pixel is 'perfectly' square, i.e. not -rectangular like in 320x200. An ellipse drawn with the same number of -pixels along both main axes will look like a perfect circle in 320x240, -but like a subtly tall ellipse in 320x200. - -Here's a function which sets the 320x240 mode. You'll notice that -it depends on the first piece of code above: - -----8<-------cut begin------ - -set320x240x256_X() - { - - /* Set the unchained version of mode 13h: */ - - set320x200x256_X(); - - /* Modify the vertical sync polarity bits in the Misc. Output - Register to achieve square aspect ratio: */ - - outportb(0x3C2, 0xE3); - - /* Modify the vertical timing registers to reflect the increased - vertical resolution, and to center the image as good as - possible: */ - - outport(0x3D4, 0x2C11); /* turn off write protect */ - outport(0x3D4, 0x0D06); /* vertical total */ - outport(0x3D4, 0x3E07); /* overflow register */ - outport(0x3D4, 0xEA10); /* vertical retrace start */ - outport(0x3D4, 0xAC11); /* vertical retrace end AND wr.prot */ - outport(0x3D4, 0xDF12); /* vertical display enable end */ - outport(0x3D4, 0xE715); /* start vertical blanking */ - outport(0x3D4, 0x0616); /* end vertical blanking */ - - /* Update mode info, so future operations are aware of the - resolution: */ - - height = 240; - - } - -----8<-------cut end------ - - -As you've figured out, this mode will be completely compatible with the -utility functions presented earlier, thanks to the global variable -'height'. Boy, am I foreseeing or what! - -Other resolutions are achieved through giving other values to the sync -timing registers of the VGA, but this is quite a large and complex -subject, so I'll postpone this to later, if ever. - -Anyway, I hope I've helped getting you started using mode X. As far as -I know, the two modes I've used above should work on *any* VGA and Super -VGA available, so this is pretty stable stuff. Let me know of any -trouble, and - - good luck! - - - -3. THE ROAD FROM HERE - -I'm providing information on various libraries and archives which relate -to what this article deals with. If you want me to add anything to this -list (for future articles), let me know, although I can't promise anything. -I am assuming you have ftp access. - - -wuarchive.wustl.edu:/pub/MSDOS_UPLOADS/programming/xlib06.zip - -This is the current de facto C/assembler library for programming -unchained modes (do not confuse with a X Windows library). All sources -are included, and the library is totally free. It has functions for -pixels, lines, circles, bezier curves, mouse handling, sprites (bitmaps), -compiled bitmaps, and supports a number of resolutions. The version number -('06') is current as of November 1993. - - -graphprg.zip - -Michael Abrash' articles in Doctor Dobbs Journal is always mentioned -with awe. In this 350 Kb archive, most of his interesting stuff has -been gathered. Read about Mode X development and techniques from month -to month. Included is also all the individual source code snippets from -each article, and also the full XSHARP library providing linedrawing, -polygons, bitmaps, solid 3D projection and speedy rendering, and even an -implementation of 2D texture mapping (can be used for quasi-3D texture -mapping), plus an article on assembly optimization on the i86 processor -family. Definitely recommended. - - -oak.oakland.edu:/pub/msdos/vga/vgadoc2.zip - -This is a bare bones VGA register reference. It also contains register -references for the CGA, EGA and Hercules cards, in addition to dozens of -SuperVGAs. Check out the BOOKS section for some decent VGA references -though - you don't want to start tweaking without a real one. - - -wuarchive.wustl.edu:/pub/MSDOS_UPLOADS/programming/tweak15b.zip - -TWEAK might be of interest to the more adventurous reader. TWEAK lets you -play around with the registers of the VGA in an interactive manner. -Various testing screens for viewing your newmade modes are applied at -the press of a key. Version 1.5 adds a test screen which autodetects your -graphics mode and displays various information about resolutions etc. -Keep a VGA reference handy. Don't try it if this is the first time you've -heard of 'registers' or 'mode X' or 'tweaking'. I was planning a version -based on the Turbo Vision interface, but time has been short. Maybe later! - - - - -4. BOOKS ON THE SUBJECT - -Extremely little has been published in written form about using -'Mode X'-style modes. Below are some books which cover VGA programming -at varying degrees of technical level, but the only one to mention -unchained modes and Mode X, is Michael Abrash'. I'd get one of the VGA -references first, though. - - o George Sutty & Steve Blair : "Advanced Pogrammer's Guide to the - EGA/VGA" from Brady. A bit old perhaps, but covers all *standard* - EGA/VGA registers, and discusses most BIOS functions and other - operations. Contains disk with C/Pascal/assembler source code. - There's a sequel out for SuperVGAs, which I haven't seen. - - o Michael Abrash : "Power Graphics Programming" from QUE/Programmer's - Journal. Collections of (old) articles from Programmer's Journal on - EGA/VGA, read modes and write modes, animation, tweaking (320x400 - and 360x480). His newer ravings in DDJ covers fast 256-color - bitmaps, compiled bitmaps, polygons, 3D graphics, texture mapping - among other stuff. - - o Richard F. Ferraro : "Programmer's Guide to the EGA and VGA video - cards including Super VGA". I don't have this one, but heard it's - nice. Detailed coverage of all EGA/VGA registers. The Super VGA - reference makes it attractive. - - o Richard Wilton : "Programmer's Guide to PC & PS/2 Video Systems" - Less technical, more application/algorithm oriented. Nice enough, - even though it is a bit outdated, in that he discusses CGA and - Hercules cards just as much as EGA/VGA. - - - - -5. BYE - FOR NOW - -I am considering writing a text describing in more detail the process of -using TWEAK to achieve the VGA resolution you want or need. However, I -thought I'd let this document go first, and see if I get any reactions. -If I don't, I'll stop.
