Serial ATA
The I/O Hub (82801FBM) provides two Serial ATA150 connections through the J2 connector. Serial
ATA is an enhancement of parallel ATA, but is not limited by the traditional restrictions of parallel
ATA. Serial ATA has higher performance characteristics with respect to speed and EMV. Serial ATA
starts with a transfer rate of 150 Mbytes/s as compared to the legacy Parallel ATA devices that were
limited to ATA133 (133MHz) or slower (33/66/100 MHz). In the future, it is hoped that SATA can be
expanded up to 600 Mbytes/s to accommodate future advanced developments. Serial ATA is
completely protocol and software compatible to parallel ATA.

Additional Universal Serial Bus (USB) Ports
The J2 connector supports two additional USB ports for a total of six USB ports for the baseboard. The
features for these two additional USB ports are the same as the four USB ports on the J1 connector.
