    3234The ICH (properly known as the 82801AA), ICH0 (82801AB), 
    33 ICH2 (82801BA) and ICH3 (82801CA/CAM) are Intel chips that are a part of 
     35ICH2 (82801BA), ICH3 (82801CA/CAM) and later devices 
     36are Intel chips that are a part of 
    3437Intel's '810' chipset for Celeron-based PCs, 
    3538'810E' chipset for Pentium-based PCs, '815E' chipset, and others.

     73The ICH4 supports a special 3-byte address (command code 
    7174plus 2 more bytes) I2C block read. 
    7275The driver and the kernel i2c protocol stack do not 
    7376support this. 
     77The ICH5 and higher support a standard 1-byte address (command code) 
     78I2C block read. The driver does support this.
