PCMCIA Interface

The notebook computer contains two PCMCIA slots for high-speed data transfers (Mono versions contain one slot).  For notebooks with two slots, you can use two Type I or II PCMCIA cards or one Type III PCMCIA card.  Mono versions accept one Type I, II, or III PCMCIA card.  All slots accept 3.3 V dc or 5 Vdc PCMCIA cards.


Real-Time Clock (RTC)

The RTC contains a lithium battery that provides power for non-volatile CMOS configuration information when power is removed from the notebook computer.

Trackball

This FRU serves as the notebook computers main pointing device.


Device Mapping

These Help topics list mapping and address information related to computer memory and various main logic board devices (keyboard controller, interrupt controller, DMA controller, etc.).

Your computer's memory and address locations are allocated at the factory to operate within a standard PC environment.  However, due to the number of optional devices that are available, sometimes memory and address locations need to be changed.  For example, some network PCMCIA cards require a specific memory location.  If that location is already allocated, a memory conflict results and the PCMCIA card will not operate as expected.  Note that some memory, I/O and interrupt locations can be changed using the BIOS Setup utility.  Refer to Setup and Configuration for additional information.
