the character set consists of 16 bytes for each of the 128 characters,

where each of the 16 bytes describes the pixels in one scan line,

most significant bit leftmost

SeeAlso: AH=00h,AH=0Bh/BH=02h,AH=11h"Tandy 2000",AH=12h"Tandy 2000"

SeeAlso: INT 52"Tandy 2000"

--------V-101000-----------------------------

INT 10 - VIDEO - SET SINGLE PALETTE REGISTER (PCjr,Tandy,EGA,MCGA,VGA)

AX = 1000h

BL = palette register number (00h-0Fh)

= attribute register number (undocumented) (see #00017)

BH = color or attribute register value

Return: nothing

Notes: on MCGA, only BX = 0712h is supported

under UltraVision, the palette locking status (see AX=CD01h)

determines the outcome

SeeAlso: AX=1002h,AX=1007h,AX=CD01h

(Table 00017)

Values for attribute register number:

10h attribute mode control register (should let BIOS control this)

11h overscan color register (see also AX=1001h)

12h color plane enable register (bits 3-0 enable corresponding

text attribute bit)

13h horizontal PEL panning register

14h color select register

--------V-101001-----------------------------

INT 10 - VIDEO - SET BORDER (OVERSCAN) COLOR (PCjr,Tandy,EGA,VGA)

AX = 1001h

BH = border color (00h-3Fh)

Return: nothing

BUG: the original IBM VGA BIOS incorrectly updates the parameter save area

and places the border color at offset 11h of the palette table

rather than offset 10h

Note: under UltraVision, the palette locking status (see AX=CD01h)

determines the outcome

SeeAlso: AX=1002h,AX=1008h,AX=CD01h

--------V-101002-----------------------------

INT 10 - VIDEO - SET ALL PALETTE REGISTERS (PCjr,Tandy,EGA,VGA)

AX = 1002h

ES:DX -> palette register list (see #00018)

BH = 00h to avoid problems on some adapters
