Rosebud72490, welcome to the Seven Forums.
I would start with going here, Model Content Page
for the display driver
. According to the specs for that model Toshiba you need the ATI driver.
For the "base system", at a guess I would say that they are likely the card reader and possibly the touchpad (or fingerprint reader if it came with one; guessing on this one due to there being a download for it). Can tell you for sure if you could provide the vendor and device ID's, Device Manager - Finding Unknown Devices
