NetVista™ Technical Information Manual
The following connectors are available on the integrated audio controller:
• Line/headphone out connector for connecting headphones or powered speakers.
To hear audio from the adapter you must connect headphones or a set of
speakers to the Line out port. These speakers must be powered with a built-in
amplifier. In general, powered speakers are available with a wide range of
features and power outputs.
• Line in connector for connecting musical devices, such as a portable CD player or
stereo system.
•
Microphone
connector for attaching a microphone.
Network connection
Some models of the NetVista computer have an integrated Ethernet controller.
Features of the Ethernet controller are:
• Operates in shared 10BASE-T or 100BASE-TX environment
• Transmits and receives data at 10 Mbps or 100 Mbps
• Has a RJ-45 Ethernet connector for LAN attachment
• Supports Wake on LAN
• Supports Remote Program Load (RPL) and Dynamic Host Configuration Protocol
(DHCP)
Real-time clock and CMOS
The real-time clock is a low-power clock that provides a time-of-day clock and a
calendar. The clock settings are maintained by the battery when the power cord is
removed.
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.
Flash EEPROM
The system board uses 4 Mb of flash electrically erasable, programmable, read-only
memory (EEPROM) to store the BIOS, IBM logo, Configuration/Setup Utility, and Plug
and Play data.
If necessary, the EEPROM can be easily updated using a stand-alone program that is
available on a 3.5-inch diskette. For information to obtain the latest version of the
Flash Update Utility program, see the
NetVista User Guide .
Expansion adapters
The NetVista small form factor desktop model computer has two 32-bit, 33 MHz PCI
slots. The NetVista desktop model computer has three 32-bit 33 MHz PCI slots.
These connectors support the 5 V signaling environment that is defined in
PCI Local
Bus Specification 2.2
. Some models also have a preinstalled AGP adapter.
