Int 10/AH=00h

VIDEO - SET VIDEO MODE

AH = 00h
AL = desired video mode (see #00010)

Return:
AL = video mode flag (Phoenix, AMI BIOS)
20h mode > 7
30h modes 0-5 and 7
3Fh mode 6
AL = CRT controller mode byte (Phoenix 386 BIOS v1.10)

Desc: Specify the display mode for the currently active display adapter

For Ahead adapters, the signature "AHEAD" at C000h:0025h. For Paradise adapters, the signature "VGA=" at C000h:007Dh. For Oak Tech OTI-037/057/067/077 chipsets, the signature "OAK VGA" at C000h:0008h. For ATI adapters, the signature "761295520" at C000h:0031h; the byte at C000h:0043h indicates the chipset revision: 31h for 18800 32h for 18800-1 33h for 18800-2 34h for 18800-4 35h for 18800-5 62h for 68800AX (Mach32) (see also #00732) the two bytes at C000h:0040h indicate the adapter type "22" EGA Wonder "31" VGA Wonder "32" EGA Wonder800+ the byte at C000h:0042h contains feature flags

bit 1:

bit 4:
Programmable video clock the byte at C000h:0044h contains additional feature flags if chipset byte > 30h (see #00009). For Genoa video adapters, the signature 77h XXh 99h 66h at C000h:NNNNh, where NNNNh is stored at C000h:0037h and XXh is 00h for Genoa 6200/6300 11h for Genoa 6400/6600 22h for Genoa 6100 33h for Genoa 5100/5200 55h for Genoa 5300/5400 for SuperEGA BIOS v2.41+, C000h:0057h contains the product level for Genoa SuperEGA BIOS v3.0+, C000h:0070h contains the signature "EXTMODE", indicating support for extended modes

Notes: IBM standard modes do not clear the screen if the high bit of AL is set (EGA or higher only). The Tseng ET4000 chipset is used by the Orchid Prodesigner II, Diamond SpeedSTAR VGA, Groundhog Graphics Shadow VGA, Boca Super X VGA, Everex EV-673, etc.. Intercepted by GRAFTABL from Novell DOS 7 and Caldera OpenDOS 7.01.

B800 DEC VAXmate AT&T mode Notes: [1] interlaced only [2] for ATI EGA Wonder, mode 08h is only valid if SMS.COM is loaded resident. SMS maps mode 08h to mode 27h if the byte at location 0040:0063 is 0B4h, otherwise to mode 23h, thus selecting the appropriate (monochrome or color) 132x25 character mode. for ATI VGA Wonder, mode 08h is the same, and only valid if VCONFIG loaded resident [3] early XGA boards support 132-column text but do not have this BIOS mode [4] DESQview intercepts calls to change into these two modes (21h is page 0, 22h is page 1) even if there is no Hercules graphics board installed [5] ATI BIOS v4-1.00 has a text-scrolling bug in this mode [6] for AT&T VDC overlay modes, BL contains the DEB mode, which may be 06h, 40h, or 44h [7] BIOS text support is broken in this undocumented mode; scrolling moves only about 1/3 of the screen (and does even that portion incorrectly), while screen clears only clear about 3/4. [8] The Oak OTI-037/067/077 modes are present in the Oak VGA BIOS, which OEMs may choose to use only partially or not at all; thus, not all Oak boards support all "Oak" modes listed here [9] this card uses the full 128K A000h-BFFFh range for the video buffer, precluding the use of a monochrome adapter in the same system [10] mode 17h supported by Tseng ET4000 BIOS 8.01X dated 1990/09/14, but not v8.01X dated 1992/02/28; mode 21h supported by 1992/02/28 version but not 1990/09/14 version [11] HERKULES simulates a 90x45 text mode in Hercules graphics mode; the installation check for HERKULES.COM is the signature "Herkules" two bytes beyond the INT 10 handler [12] The Realtek RTVGA BIOS v3.C10 crashes when attempting to switch into modes 21h or 27h; this version of the BIOS also sets the BIOS data area incorrectly for extended text modes, resulting in scrolling after only 24 lines (the VMODE.EXE utility does set the data area correctly) [13] The Tandy 1000SL/TL BIOS does not actually support this mode [14] HERCULES.COM is a graphics-mode BIOS extension for Hercules-compatible graphics cards by Soft Warehouse, Inc. Its installation check is to test whether the word preceding the INT 10 handler is 4137h. [15] The Hercules-graphics video modes for HERCBIOS (shareware by Dave Tutelman) may be changed by a command-line switch; the 90x43 character-cell mode's number is always one higher than the 90x29 mode (whose default is mode 08h) [16] Stealth64 Video 2001-series BIOS v1.03 reports 76 lines for mode 7Ch, resulting in incorrect scrolling for TTY output (scrolling occurs only after the end of the 76th line, which is not displayed) [17] For 43-line text on EGA or 43/50-line text on VGA, you must load an 8x8 font using AX=1102h after switching to mode 3; VGA may also require using INT 10/AH=12h/BL=30h
