Problems?

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