24 Forcibly enable the SMBus controller. DANGEROUS!
26 Forcibly enable the SMBus at the given address. EXTREMELY DANGEROUS!
31 i2c-viapro is a true SMBus host driver for motherboards with one of the
32 supported VIA south bridges.
34 Your lspci -n listing must show one of these :
36 device 1106:3050 (VT82C596A function 3)
37 device 1106:3051 (VT82C596B function 3)
38 device 1106:3057 (VT82C686 function 4)
39 device 1106:3074 (VT8233)
40 device 1106:3147 (VT8233A)
41 device 1106:8235 (VT8231 function 4)
42 device 1106:3177 (VT8235)
43 device 1106:3227 (VT8237R)
45 If none of these show up, you should look in the BIOS for settings like
46 enable ACPI / SMBus or even USB.
48 Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
49 VT8231), this driver supports I2C block transactions. Such transactions
50 are mainly useful to read from and write to EEPROMs.
