PCI[edit | edit source]

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:

Supported devices:

Device ID Device "Name" Firmware
104D8183 Sony IFB ATHENS Board Revision 0x1 010.??? to 4.91
104D81FF Sony PIF5 TMR Board Revision 0x101 060.004 to 4.91
104D8200 Sony DVE (RSX Tracing) FPGA 082.006 to 4.91
104D820E Sony CXD9208GP PS2 emulation subsystem adapter 082.006 to 4.91
80861076 Intel 82541PI Gigabit Ethernet Controller 010.??? to 4.91

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
