Piggybacked: ICH4 Southbridge
Southbridge ICH4, also known as FW82801DB
The ICH4 supports ATA/ 100 for hard drives. Theoretically, that equals a maximum possible transfer rate of 100 MByte/second. Bandwidths of up to 480 Mbit/second are possible with USB2.0. The controller is also backwards-compatible with USB 1.1, which allows a bandwidth of only 12 Mbit/second. USB uses it primarily for data transfer to scanners, printers and digital cameras.
