Problems? |

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. |
