Product Summary

The NH82801GBM is an I/O Controller. It provides extensive I/O support. The NH82801GBM incorporates a variety of PCI functions that are divided into six logical devices (B0:D27, B0:D28, B0:D29, B0:D30, B0:D31 and B1:D8). D30 is the DMI-to-PCI bridge and the AC 97 Audio and Modem controller functions, D31 contains the PCI-to-LPC bridge, IDE controller, SATA controller, and SMBus controller, D29 contains the four USB UHCI controllers and one USB EHCI controller, and D27 contains the PCI Express root ports. B1:D8 is the integrated LAN controller.
