It would depend on what you are trying to do. If you are trying to display characters and control the foreground and background colors, then try functions AH=9 or AH=13h.

A quick example:

Code Select Expand


.model small
.stack
.data
  str1 db "a",1,"b",2,"c",3,"d",4,"e",5,"f",6,"g",7,"h",8
       db "i",9,"j",10,"k",11,"l",12,"m",13,"n",14,"o",15
.code
.startup
    mov ah, 13h     ; function number
    mov al, 11b     ; mode (char-attribute, update cursor)
    mov bh, 0       ; page number
    mov cx, 15      ; length of string
    mov dh, 0       ; start at row 0
    mov dl, 0       ; start at column 0
    push ds         ; es:bp -> string
    pop es
    mov bp, OFFSET str1
    int 10h

    mov ah, 9       ; function number
    mov al, "X"     ; character
    mov bh, 0       ; page number
    mov bl, 14h     ; attribute, red on blue
    mov cx, 4       ; repeat count
    int 10h

    mov ah, 0       ; wait for key press
    int 16h
.exit
end
