We do not have any documentation for the CX700, but it was reported
to work fine. Thanks to Claas Langbehn for testing.

If none of these show up, you should look in the BIOS for settings like
enable ACPI / SMBus or even USB.

Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
VT8231), this driver supports I2C block transactions. Such transactions
are mainly useful to read from and write to EEPROMs.
