• Two SATA (Serial ATA) interfaces which are compliant with
SATA 1.0 specification (1.5Gbps interface)
Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance even in data intensive environments such as audio/
video, consumer electronics and entry-level servers.
PCI Bus Master IDE Controller
• Two PCI IDE interfaces support up to four IDE devices
• Supports ATA/33, ATA/66 and ATA/100 hard drives
• PIO Mode 4 Enhanced IDE (data transfer rate up to 14MB/
sec.)
• Bus mastering reduces CPU utilization during disk transfer
• Supports ATAPI CD-ROM, LS-120 and ZIP
IrDA Interface
The system board is equipped with an IrDA connector for wire-
less connectivity between your computer and peripheral devices.
The IRDA (Infrared Data Association) specification supports data
transfers of 115K baud at a distance of 1 meter.
USB Ports
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1
suppor ts 12Mb/second bandwidth while USB 2.0 suppor ts
480Mb/second bandwidth providing a marked improvement in
device transfer speeds between your computer and a wide range
of simultaneously accessible external Plug and Play peripherals.
