On certain Compaq portable products (including the Armada line of portable computers), Compaq has included a feature called "multi-mouse" support. This feature allows multiple PS2 pointing devices to be active on the computer simultaneously; for example the internal trackpad and an external PS2 mouse might be used and active at the same time.
Some users have requested that they be able to disable the internal pointing device when an external mouse is attached to the computer. Compaq has agreed to implement this feature in its future products, and is in the process of updating the system BIOS for certain current models.
For future products, Compaq will add a new F10/Setup option to allow the user to enable or disable the default multi-mouse mode. The default state will remain the same as today (ON), but the user will be able to set the mode OFF if they wish.
For some current products, which do not have a provision in F10/Setup to enable/disable multi-mouse mode, Compaq will supply a new DOS command-line utility called MMMODE.COM. This utility will set the mode, and save the proper flags in the computer nonvolatile memory, so that the setting is remembered across reboots.
