Int 33 Fn 0000 - MS Mouse - Reset Driver And Read Status [M]
AX = 0000h
Return: AX = status
0000h hardware/driver not installed
FFFFh hardware/driver installed
BX = number of buttons
0000h other than two
0002h two buttons (many drivers)
0003h Mouse Systems/Logitech three-button mouse
FFFFh two buttons
Notes: to use mouse on a Hercules-compatible monographics card in graphics
mode, you must first set 0040h:0049h to 6 for page 0 or 5 for page 1,
and then call this function. Logitech drivers v5.01 and v6.00
reportedly do not correctly use Hercules graphics in dual-monitor
systems, while version 4.10 does.
the Logitech mouse driver contains the signature string "LOGITECH"
three bytes past the interrupt handler; many of the Logitech mouse
utilities check for this signature.
