I/O Controller Hub - ICH9

ICH9

The ICH9 came out in May 2007 in the P35 (Bearlake) chipset. It removes all PATA support. In practice, many baseboard manufacturers continue providing PATA using an additional chip. Officially only the ICH9R, ICH9DH, ICH9DO chip have AHCI support.

This part has the following variants:

  • 82801IB (ICH9) Base officially neither AHCI or RAID support, but a simple driver INF edit shows it supports AHCI without problems
  • 82801IR (ICH9R) RAID with AHCI and RAID Support
  • 82801IH (ICH9DH) Digital Home with AHCI and no RAID Support
  • 82801IO (ICH9DO) Digital Office with AHCI and RAID Support
  • 82801IBM (ICH9M) Base Mobile
  • 82801IEM (ICH9EM) Enhanced Mobile
  • 82801IUX (ICH9M-SFF) Ultra Mobile
