PCI graphics adapter. For information on connector pin assignments, see “Monitor connector” on page 29. Audio subsystem The NetVista computer comes with an integrated audio controller. These models are capable of playing and recording sounds and support SoundBlaster, Adlib, and Microsoft Windows Sound System applications.
The system uses 242 bytes of CMOS memory to store data. The CMOS memory is erased if the CMOS clear/recovery jumper is moved. To locate the battery, see “System board layout for the NetVista A40 and A40p computer” on page 3 or “System board layout for the A20 model computer” on page 4.
The NetVista computer has a 3-pin connector on the system board that provides the auxiliary 5 volts (AUX5) and wake-up signal connections. Some Wake on LAN adapters have two connectors: a 3-pin, right-angle header for AUX5, and a 2-pin straight connector for the wake-up signal. These Wake on LAN connector options include a Y-cable that has a 3-pin system-board connector on one end and splits into the 3-pin and 2-pin connectors that connect to the adapter.
