  • CardBus controller
    • PCI ID: 1180:0476
  • IEEE1394 (FireWire)
    • PCI ID: 1180:0552

CardBus Linux support

This chip emulates the older Ricoh R5C476-II for CardBus functionality.

This function is supported by recent 2.4 and 2.6 kernels

FireWire Linux support

Only the A31p ThinkPads with this chip have the FireWire function enabled, so if you don't have the FireWire ports, you will not see it listed in lspci either.

ThinkPads this chip may be found in
