	GameDev.net - Mode X: 256-color VGA Magic
		Mode X pixels are processed in parallel, improving performance up to four times.
		Fourth, like mode 13h but unlike all other VGA modes, mode X is a byteper-pixel mode (each pixel is controlled by one byte in display memory), eliminating the slow read-before-write and bit-masking operations often required in 16-color modes.
		The VGA hardware feature that's truly the key to mode X performance is the ability to process four planes' worth of data in parallel; this includes both the latches and the capability to fan data out to any or all planes.

	Mode X - Wikipedia, the free encyclopedia
		Mode X is an undocumented video graphics display mode of the IBM VGA graphics hardware that was popularized by Michael Abrash, first published in July 1991 in Dr.
		Mode X involves tweaking IBM's standard Mode 13h 256 colour graphics mode such that all the video memory is made available to the programmer in a planar fashion, at the expense of extra complexity in writing to video memory.
		Planar mode allows up to 4 adjoining pixels to be modified in one byte write operation, which is ideal for solid filling of objects such as polygons, rectangles, lines, etc.

	Tweaked VGA modes. Mode X and related video modes
		Most of these modes can be set up on an ordinary VGA card, but you will need a monitor capable of displaying at least 800x600 to use some of these modes.
		Using an unchained mode slows you down if you are writing a lot of single pixels because you have to set the mask register before writing the pixel and setting the register takes at least as long as writing the pixel does.
		One of the real problems with using the VESA modes is that you have to use bank switching to access all the display memory used by these modes.

	Getting X Off The Hardware
		This paper lays out an alternative structure for X within the Linux environment where the responsibility for acceleration lies entirely within the existing 3D user/kernel library, the mode selection is delegated to an external library and the X server becomes a simple application layered on top of both of these.
		X servers for PC operating systems adapted to simple video mode selection by creating a 'virtual' desktop at least as large as the largest desired mode and making the current mode view a subset of that, panning the display around to keep the mouse on the screen.
		Within that mode there may be a wealth of information that is not relevant to the X server; it really only needs to know the pixel dimensions of each frame buffer, the physical dimension of pixels on each monitor and the geometric relationship among monitors.

	Mode X and Mode 13 Display Modes (Site not responding. Last check: 2007-10-22)
		Mode 13 is the linear unflippable 320x200 8 bits per pixel palettized mode known widely by its hexadecimal BIOS mode number: 13.
		Mode X is a hybrid display mode derived from the standard VGA Mode 13.
		Mode X modes are indicated by the DDSCAPS_MODEX flag in the DDSCAPS structure, which is part of the DDSURFACEDESC structure returned by the IDirectDrawSurface3::GetCaps and IDirectDraw2::EnumDisplayModes methods.

	Using X
		Hi-color modes are supported only on displays matching the exact color depth (15 or 16); true color modes are supported only on true color X displays, but always both 24 bit and 32 bit SVGA modes.
		As the typical graphics mode with 320x200x8 will be used often with large scalings and modern graphics boards are pretty fast, I added something to eat up your CPU time: you can turn on the bilinear interpolation.
		Modes that are defined but cannot be supported due to lack of video memory or because they cannot be displayed on your X display, are marked as unsupported in the VBE mode list (but are still in it).

	Hydrogenaudio Forums -> Would a new X mode be prudent?
		Mode 3 is generally the best overall for quality purposes yet it can lead to significant bitrate bloat.
		The reason that it's hard to get LAME to sound good at lower bitrates isn't because of the X modes, but because the psymodel is not very well tuned for this in many other areas.
		But I have no idea if such a mode would even have the desired improvement in quality (over -X 1 for long blocks)...it was one of those "has anybody thought about this?" things.

		Unlike the virtual hostmask mode that some other IRC networks use, UndernetÂ’s cannot be unset; the user must disconnect from Undernet to disable it.
		When X joins the channel, it will reset those modes if it is alone in the channel.
		The ability to see channel modes is extremely helpful in case the channel is locked up (channel modes +i, +l, and/or +k).

	Introduction to VGA mode 'X'
		A further note about Mode X is that is does not correspond to a particular resolution per se, but corresponds to a group of resolutions capable by the VGA hardware.
		The Mode X screen is arranged as four tables (planes), each of which is made up of 90 columns and 240 rows (for our 360x240 pixel resolution).
		My current personal project is a sprite graphics engine using Mode X at a resolution of 360x240 pixels, and I have made a fair bit of progress on this.

		The new X Sweeper is a nearfield receiver with a graphical display that displays the nearfield RF (analog only) in a spectrum format, allowing the user to rapidly observe all signals that are present, not just one single frequency at a time.
		This mode runs in parallel with SWEEP, SCAN and VFO modes and differs from the regular MEMORY in that it logs every frequency, even repeat occurences, to a separate memory allowing you to keep the first 1919 frequencies or keep the last 1919 frequencies captured.
		The X Sweeper can be tuned to a specific frequency by entering that frequencydirectly into the keypad while in VFO mode.

	Definition of Mode-X (Site not responding. Last check: 2007-10-22)
		This is an un-chained video mode, which means that you have to use a form of bank switching to access all the screen memory.
		Some benefits of this mode are hardware page flipping, multiple on-card virtual buffers (sometimes referred to as double buffers), fast horizontal line fills (used for very fast solid filled polygons), and hardware scrolling.
		Some drawbacks of this mode are that it is difficult to code for and isn't any faster than Mode 13h on a PC today.

		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_.

		In X Desktop mode a large X window is opened at the size you specify which can be smaller, equal to, or much larger than the resolution supported by your display board (see below for virtual X Desktop operation).

		TrueType fonts are presented to the X client as iso10646-1 (Unicode), which means that X clients get access to the full range of glyphs in the fonts.

	WPDOS - Text Mode Survival Guide
		If your computer cannot display full-screen mode, or if you want to experiment with different fonts, you can run WPDOS with software-based fonts in a window, but with a window that is almost the same size as the full screen.
		The reason is that the dots that make up a character in text mode do not exactly match the pixels on a flat-panel screen, and so the monitor has to display an approximation of the character.
		If none of these work, consult this dictionary of video modes (source unknown); search for "T 132" to find various modes with 132 columns, and use the hex number at the left, omitting the "h", as the command-line parameter for VMODE.EXE.

		For Mode 2, Tprop from any driver to any other device is less than or equal to Tcyc-[Tval(max)+Tskew(max)+Tcrosstalk (max)+Tsu(min)], which evaluates to 2.2 ns for Tcyc = 7.5 ns, 4.7 ns for Tcyc = 10 ns, and 9.2 ns for Tcyc = 15 ns.

		With later kernels you can put the display in graphics mode and therefore get 800x600 mode, but you will have no console capability at all, and you'll almost certainly want to set up xdm so you go right into X mode.
		However, if you do that you will have no output in console mode, and you'll need to get set up so that xdm starts automatically and puts you in X mode.
		It would not go to 800x600 mode without special coaxing, and the display contained noise and (on some or all machines) a big old fl line down the right side.
