    The SM Bus is not very important as you make work normally even if it is not installed. For you to find it simply go to where you will get all driver for you acer. Simply select the appropriate for your laptop and windows and you will get all driver for your laptop.

    When you get to the support site, be sure try both the chipset drivers plus any drivers that might be for internal card readers (these driver types seem to often resolve SM controller errors)

    to piggyback what has already been posted, if you have any support disks that came with your computer or motherboard, the drivers are likely to be on one of them. there is a CardReader driver on your computers download page though, so like Lookin said that's probably what you need.

    He will get any driver on the acerpanam website.
