| 31 | To install this driver, simply do |
|---|
| 32 | # modprobe i2c-via |
|---|
| 33 | |
|---|
| 34 | This driver uses the i2c-algo-bit module which must be |
|---|
| 35 | modprobed and/or enabled in your kernel |
|---|
| 36 | (Character Devices -> I2C Support -> I2C Bit-Banging Interfaces). |

|---|
| 38 | Problems? |
|---|
| 39 | |
|---|
| 40 | Q: You have VT82C586B on the motherboard, but not in the listing. |
|---|
| 41 | |
|---|
| 42 | A: Go to your BIOS setup, section PCI devices or similar. |
|---|
| 43 | Turn USB support on, and try again. |
|---|
| 44 | |
|---|
| 45 | Q: No error messages, but still i2c doesn't seem to work. |
|---|
| 46 | |
|---|
| 47 | A: This can happen. This driver uses the pins VIA recommends in their |
|---|
| 48 | datasheets, but there are several ways the motherboard manufacturer |
|---|
| 49 | can actually wire the lines. |
