INT 33,1F - Disable Mouse Driver
AX = 1F
on return:
AX = 001F if successful
FFFF if error
ES:BX = previous INT 33 vector
- restores vectors for INT 10 and INT 71 (8088/86) or INT 74 (286+)
- INT 33 interrupt vector (software) is not affected
- use of the vector returned in ES:BX to restore the previous INT 33
vector can cause problems since it contains the value of INT 33
before the driver was installed; any other hooks into INT 33 set
after driver installation will not receive service
