System Support
For a PCI Express x16 transfer, a lane will be re-used every17th byte of a transfer. The
mux-demux process provided by the physical layer is transparent to the other layers and to
software/drivers.
The SFF, ST, MT MT, and CMT forma factors provide two PCI Express slots: a PCI Express x16
(16-lane) slot specifically designed for a graphics controller, and a general purpose PCI Express
x1 (1-lane) slot.
4.2.3 Option ROM Mapping
During POST, the PCI bus is scanned for devices that contain their own specific firmware in
ROM. Such option ROM data, if detected, is loaded into system memory's DOS compatibility
area (refer to the system memory map shown in chapter 3).
4.2.4 PCI Interrupts
Eight interrupt signals (INTA- thru INTH-) are available for use by PCI devices. These signals
may be generated by on-board PCI devices or by devices installed in the PCI slots. For more
information on interrupts including PCI interrupt mapping refer to the “System Resources”
section 4.3.
4.2.5 PCI Power Management Support
This system complies with the PCI Power Management Interface Specification (rev 1.0). The
PCI Power Management Enable (PME-) signal is supported by the chipset and allows compliant
PCI peripherals to initiate the power management routine.
