Onboard 32-bit Audio
The standard onboard audio supported by the
810e chipset comes with audio drivers that are
supplied on the Support Disk. The audio subsys-
tem uses the onboard Line-In, Mic and Line-Out
jacks to connect external devices and also uses any
of the onboard CD-ROM audio-in connectors to
process audio from a system CD-ROM drive.
The standard audio includes an AC’ 97
DAC/ADC built into the audio CODEC. This
reduces noise to improve audio quality and per-
formance for a signal-to-noise ratio of +90dB,
which greatly improves voice synthesis and recog-
nition.
The enhanced model of the BIW2A-AT replaces
the standard audio with an enhanced Creative
Labs 5880 audio chip and codec that use different
audio drivers which are also on the Support Disk.
Expansion Options
This motherboard has five 32-bit Revision 2.2 PCI
expansion slots for PCI expansion cards. All slots
are Bus Master capable. In addition, there is a slot
for an optional Modem Riser card that provides
an onboard telephony connection.
ACPI Ready
ACPI (Advanced Configuration and Power Inter-
face) support provides more energy saving func-
tions for operating systems that support ACPI
such as Windows 98. An ACPI-capable system
can use the ACPI OnNow feature to turn off sys-
tem peripherals and wake the system up from
Suspend mode via several means including point-
ing device movement and key commands.
