Chipset
(continued)
The integrated Ultra DMA-33/66/100 master mode
EIDE controller with enhanced PCI bus com-
mands.
The UltraDMA-33/66/100 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 interface. The SB chipset also sup-
ports ATAPI compliant devices including DVD
devices and four USB 1.1 ports for serial transfers
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.
Memory The board has three DIMM sockets for the instal-
lation of 168-pin, 3.3V non-buffered DIMM
memory modules. The DIMM memory modules
can be SDRAM or VCM memory chips.
VGA This mainboard includes a 4xAGP slot that pro-
vides 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 specification, and supports 18-bit ADC
(Analog Digital Converter) and DAC (Digital Ana-
log Converter) resolution as well as 18-bit stereo
full-duplex codec with independent and variable
sampling rates. Further features include support
for four analog line-level stereo inputs.
Expansion
Options
Four 32-bit PCI slots, an AGP slot, two ISA slots
and an AMR slot provide plenty of expansion po-
