Accelerated Graphics Port (AGP)
The AGP slot on the board is compliant with the new AGP 3.0 specification. This
new specification enhances the functionality of the original AGP specification by
allowing 8X data transfers ( 8 data samples per clock) resulting in maximum band-
width of 2.1GB/s. In addition, it defines 1.5 volt power supply operation. Complying
with this specification, this board supports external AGP-8X/4X cards with Fast
Write Transactions. Only 1.5V AGP cards are supported.
Ultra ATA/66/100/133
This mainboard provides two independent ATA133 IDE controllers, supporting
standard programmable input/output (PIO) and Direct Memory Access (DMA)
mode operations, as well as UltraDMA-133/100/66/33 standards for a maximum data
transfer rate of 133MB/sec per channel.
Hardware Monitoring
Hardware monitoring enables you to monitor various aspects of the system operation
and status. The features include CPU temperature, voltage and fan speed in RPMs.
LAN (Optional)
This mainboard is optionally mounted with a LAN chipset. It allows the mainboard to
connect to a local area network by means of a network hub.
Serial ATA (Optional)
The evolutionary serial ATA interface replaces the standard parallel ATA physical
storage interface. The serial ATA specification provides scalability and allows
future enhancements to the computing platform. Serial technology overcomes
performance limits of parallel interface architecture, meeting the escalating need for
faster data throughput in servers and storage devices.
Serial ATA is completely software compatible with parallel ATA, requiring no
modification to your operating system. The serial ATA interface cable requires lower
voltages and uses smaller cable connectors, providing ease of installation. You can
easily upgrade storage devices that are compatible with the serial ATA interface
specification.
