4 Video Mode Selection Support 2.13
12 This small document describes the "Video Mode Selection" feature which
21 enter ``scan`` on the video mode prompt, pick the mode you want to use,
22 remember its mode ID (the four-digit hexadecimal number) and then
25 The video mode to be used is selected by a kernel parameter which can be
31 NORMAL_VGA - Standard 80x25 mode available on all display adapters.
33 EXTENDED_VGA - Standard 8-pixel font mode: 80x43 on EGA, 80x50 on VGA.
35 ASK_VGA - Display a video mode menu upon startup (see below).

44 0x.... - Hexadecimal video mode ID (also displayed on the menu, see below
51 The ASK_VGA mode causes the kernel to offer a video mode menu upon

76 next section for a description of mode IDs).
78 <flashing-cursor-here> encourages you to enter the item number or mode ID
80 "Unknown mode ID", it is trying to tell you that it isn't possible to set such
81 a mode. It's also possible to press only <RETURN> which leaves the current mode.
83 The mode list usually contains a few basic modes and some VESA modes. In
86 BIOSes are often shipped with the same card and the mode numbers depend purely
94 If you are not happy with the mode list offered (e.g., if you think your card
95 is able to do more), you can enter "scan" instead of item number / mode ID. The
96 program will try to ask the BIOS for all possible video mode numbers and test
103 After scanning, the mode ordering is a bit different: the auto-detected SVGA
107 Mode IDs
110 Because of the complexity of all the video stuff, the video mode IDs
111 used here are also a bit complex. A video mode ID is a 16-bit number usually
112 expressed in a hexadecimal notation (starting with "0x"). You can set a mode
113 by entering its mode directly if you know it even if it isn't shown on the menu.
121 0x0100 to 0x017f - standard BIOS modes. The ID is a BIOS video mode number
124 0x0200 to 0x08ff - VESA BIOS modes. The ID is a VESA mode ID increased by
133 0x0f00 standard 80x25, don't reset mode if already set (=FFFF)
137 0x0f04 leave current video mode
145 E.g., 0x1950 corresponds to a 80x25 mode, 0x2b84 to 132x43 etc.
146 This is the only fully portable way to refer to a non-standard mode,
147 but it relies on the mode being found and displayed on the menu
148 (remember that mode scanning is not done automatically).
154 If you add 0x8000 to the mode ID, the program will try to recalculate
155 vertical display timing according to mode parameters, which can be used to

205 2.1 (30-Jan-96) VESA modes moved to 0x200-0x3ff. Mode selection by resolution
215 Screen contents retained during mode changes.
221 Added a Tseng 132x60 mode.
222 2.5 (19-Mar-96) Fixed a VESA mode scanning bug introduced in 2.4.
226 cards use very strange mode numbers.
230 - Added support for special Video7 mode switching functions
237 - Better recognition of text modes during mode scan.
