There is an integrated USB controller with a built-in root hub and
four function ports. The integrated Ultra DMA-33/66 master
mode EIDE controller with enhanced PCI bus commands.
The UltraDMA-33/66 Master Mode PCI EIDE controller features
dual channel master mode PCI supporting Enhanced IDE (EIDE)
devices and employ transfer rates up to 33 MB/sec to cover PIO
mode 4, multi-word DMA mode 2 drives, and UltraDMA-33 inter-
face. The SB chipset also supports ATAPI compliant devices
including DVD devices and four USB 1.1 ports for serial trans-
fers at 12 or 1.5 Mbits/sec.
The integrated super IO controller supports two serial ports, an
IR port, parallel port, and floppy disk controller functions. There
is also system monitor support, providing system feedback of
voltage, temperature, and fan speed conditions.
Inexpensive Memory
The board has three DIMM sockets for the installation of 168-pin,
3.3V non-buffered DIMM memory modules. The DIMM memory
modules can be SDRAM or VCM memory chips.
4xAGP Graphics Adapter Slot
The MB694A includes a 4xAGP slot that provides four times the
bandwidth of the original AGP specification. AGP technology
provides a direct connection between the graphics sub-system
and the processor so that the graphics do not have to compete
for processor time with other devices on the PCI bus.
The AGP design allows the graphics controller to use part of the
main memory when it needs it, for example, in handling the very
large texture maps required by virtual reality and 3D video
games and applications.
AC 97 Audio Codec
The AC 97 Audio codec is compliant with the AC 97 2.1 specifi-
cation, and supports 18-bit ADC (Analog Digital Converter) and
DAC (Digital Analog Converter) resolution as well as 18-bit ste-
reo full-duplex codec with independent and variable sampling
rates. Further features include support for four analog line-level
stereo inputs.
