INT 33 - MS MOUSE v3.0+ - DEFINE GRAPHICS CURSOR AX = 0009h BX = column of cursor hot spot in bitmap (-16 to 16) CX = row of cursor hot spot (-16 to 16) ES:DX -> mask bitmap (see #03170) Notes: in graphics modes, the screen contents around the current mouse cursor position are ANDed with the screen mask and then XORed with the cursor mask the Microsoft mouse driver v7.04 and v8.20 uses only BL and CL, so the hot spot row/column should be limited to -128..127 Microsoft KnowledgeBase article Q19850 states that the high bit is right-most, but that statement is contradicted by all other available documentation SeeAlso: AX=000Ah,AX=0012h,AX=002Ah,INT 62/AX=007Fh,INT 6F/AH=0Ah"F_DEF_MASKS"
