SYSTEM - POINTING DEVICE BIOS INTERFACE (PS) - RESET

AX = C201h

Return:
CF set on error AH = status (see #00522) CF clear if successful BH = device ID BL = value returned by attached device after reset AAh if device is a mouse

Notes: After successful completion of this call, the pointing device is set

as follows:
Disabled, sample rate 100 Hz, resolution 4 counts/mm, scaling 1:1, unchanged data package size. This function should be called before rebooting the system (see INT 15/AH=4Fh), since otherwise the mouse may behave erratically on some systems after the boot. Before calling this function, the caller should check that the INT 15h vector is in fact initialized (on some very old machines the IVT may contain 0000h:0000h).. IBM classifies this function as required
