== PCI ==
Bus, resembling Conventional PCI 2.3, directly connected to [[South Bridge]], with 80 exposed pads

Activated by setting offset 0x48C02 in [[SC EEPROM]] to 0x00 or 0x03:
* 0x00 is for IFB (InterFace Board, used by [[SKU_Models_Nonretail#Nonretail_prototypes_.28CEB.29|CEB]])
* 0x03 is for [[Communication Processor]] (PIF5, used by [[SKU_Models_Nonretail#Reference_tool_prototypes_.28DEHR.29|DEH-R10XX]] and [[DECR-1000]])
** Does also have support for '''all''' ''retail platforms'' (e.g. [[COK-00x#COK-001|COK-001]], [[VER-00x#VER-001|VER-001]] or [[RTX-00x#RTX-001|RTX-001]])

Major differences from PCI standard:
* smaller formfactor (80 pin, instead of miniPCI 100P-type I/II or MiniPCI 124P-Type III)
* no use of miniPCI standard sideband signals for audio and communications
* no support of the miniPCI standard CLKRUN# signal defined in the PCI Mobile Design Guide
* no support for optional JTAG signals, nor for the 64-bit PCI extension defined in the PCI Local Bus Specification
