4 Video Mode Selection Support 2.13

21 remember its mode ID (the four-digit hexadecimal number) and then
24 The video mode to be used is selected by a kernel parameter which can be
30 NORMAL_VGA - Standard 80x25 mode available on all display adapters.
32 EXTENDED_VGA - Standard 8-pixel font mode: 80x43 on EGA, 80x50 on VGA.

50 The ASK_VGA mode causes the kernel to offer a video mode menu upon

75 next section for a description of mode IDs).

79 "Unknown mode ID", it is trying to tell you that it isn't possible to set such
80 a mode. It's also possible to press only <RETURN> which leaves the current mode.
82 The mode list usually contains a few basic modes and some VESA modes. In
85 BIOSes are often shipped with the same card and the mode numbers depend purely
93 If you are not happy with the mode list offered (e.g., if you think your card
94 is able to do more), you can enter "scan" instead of item number / mode ID. The
95 program will try to ask the BIOS for all possible video mode numbers and test
102 After scanning, the mode ordering is a bit different: the auto-detected SVGA
106 Mode IDs
109 Because of the complexity of all the video stuff, the video mode IDs
110 used here are also a bit complex. A video mode ID is a 16-bit number usually
111 expressed in a hexadecimal notation (starting with "0x"). You can set a mode
112 by entering its mode directly if you know it even if it isn't shown on the menu.
120 0x0100 to 0x017f - standard BIOS modes. The ID is a BIOS video mode number
123 0x0200 to 0x08ff - VESA BIOS modes. The ID is a VESA mode ID increased by
132 0x0f00 standard 80x25, don't reset mode if already set (=FFFF)
136 0x0f04 leave current video mode
144 E.g., 0x1950 corresponds to a 80x25 mode, 0x2b84 to 132x43 etc.
145 This is the only fully portable way to refer to a non-standard mode,
146 but it relies on the mode being found and displayed on the menu
147 (remember that mode scanning is not done automatically).
153 If you add 0x8000 to the mode ID, the program will try to recalculate
154 vertical display timing according to mode parameters, which can be used to

204 2.1 (30-Jan-96) VESA modes moved to 0x200-0x3ff. Mode selection by resolution
214 Screen contents retained during mode changes.
220 Added a Tseng 132x60 mode.
221 2.5 (19-Mar-96) Fixed a VESA mode scanning bug introduced in 2.4.
225 cards use very strange mode numbers.
229 - Added support for special Video7 mode switching functions
236 - Better recognition of text modes during mode scan.
