ICH7 Family Datasheet
The ICH7 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) as listed in
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.
PCI Devices and Functions
NOTES:
1.
The following sub-sections provide an overview of the ICH7 capabilities.
Direct Media Interface (DMI)
Direct Media Interface (DMI) is the chip-to-chip connection between the Memory
Controller Hub / Graphics Memory Controller Hub ((G)MCH) and I/O Controller Hub 7
(ICH7). This high-speed interface integrates advanced priority-based servicing allowing
for concurrent traffic and true isochronous transfer capabilities. Base functionality is
completely software-transparent, permitting current and legacy software to operate
normally.
