Editing PCIe

<div style="float:right">[[File:TMU-520_1-871-645-11_A_Detail_9_(CP_Con.).jpg|200px|thumb|left|PCIe x4 connector above the Communication Processor (PCI) connector on a TMU-520]]</div>

== PCIe ==
Bus, resembling [https://en.wikipedia.org/wiki/PCI_Express Conventional PCIe] x4 1.0, partly connected to [[South Bridge]], with 200 exposed pads.<br>
Can be activated by setting the [[Repository_Nodes|Repository Node]] ''sys.lv1.iosys.pciex'' to ''1'' (in [[sysctl.txt]]). The PCIe MMIO address space can be extended to 1GB by setting ''sys.lv1.large_pciex'' to ''1''.<br>
Does only support the following PCIe devices (depending on the firmware version):
* "1033 0125" (NEC µPD720400 PCI Express - PCI/PCI-X Bridge)
* Nvidia NV47 graphics card (depending on the video bios build)

=== 200-pin layout ===
CN4351 200P  on [[DECR-1000]] [[TMU-520]]
