BX    number of mouse buttons

Info: This performs a "software reset" of the mouse support.  It sets

all internal variables to their standard defaults, as described

under INT 33H 0000H.

This works like INT 33H 0000H except that it does not perform a

reset of the mouse hardware or of any hardware-related variables

(some older mouse hardware takes several seconds to reset).
