— Realtek ALC203 Audio Codec
The ALC203 is a 20-bit DAC and 18-bit ADC full-duplex AC'97 2.3 compatible stereo audio
CODEC designed for PC multimedia systems, including host/soft audio, and AMR/CNR
based designs.
The ALC203 incorporates proprietary converter technology to achieve a high SNR (greater
than 100 dB), sensing logics for device reporting, and a Universal Audio Jack® for
improved user convenience. The ALC203 AC'97 CODEC supports multiple CODEC
extensions with independent variable sampling rates and built-in 3D effects. The ALC203
CODEC provides two pairs of stereo outputs with independent volume controls, a mono
output, multiple stereo and mono inputs, along with flexible mixing, gain, and mute
functions to provide a complete integrated audio solution for PCs.

Realtek RTL8101L Ethernet Controller
The Realtek RTL8101L is a single-chip Fast Ethernet controller that provides 32-bit
performance, PCI bus master capability, and full compliance with IEEE 802.3u 100Base-TX
specifications and IEEE 802.3x Full Duplex Flow Control. It also supports the Advanced
Configuration Power management Interface (ACPI), PCI power management for modern
operating systems that are capable of Operating System Directed Power Management
(OSPM) to achieve the most efficient power management possible. The RTL8101L no
longer supports CardBus mode as RTL8139C does.
In addition to the ACPI feature, the RTL8101L also supports remote wake-up (including
AMD Magic Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM
environments. The RTL8101L is capable of performing an internal reset through the
application of auxiliary power. When auxiliary power is applied and the main power remains
off, the RTL8101L is ready and waiting for the Magic Packet or Link Change to wake the
system up. Also, the LWAKE pin provides 4 different output signals including active high,
active low, positive pulse, and negative pulse. The versatility of the RTL8101L LWAKE pin
provides motherboards with Wake-On-LAN (WOL) functionality.
The RTL8101L also supports Analog Auto-Power-down, that is, the analog part of the
RTL8101L can be shut down temporarily according to user requirements or when the
RTL8101L is in a power down state with the wakeup function disabled. In addition, when
the analog part is shut down and the IsolateB pin is low (i.e. the main power is off), then
both the analog and digital parts stop functioning and the power consumption of the
RTL8101L will be negligible. The RTL8101L also supports an auxiliary power auto-detect
function, and will auto-configure related bits of their own PCI power management registers
in PCI configuration space.
