base system drivers could be related with chipset, rapid storage, HDD protection. make sure you update all your drivers

Just what do you mean by base system device? Are you relating to the Windows Operting system or what?

when you get a base system device in the other devices category in device manager it usually means that either the chipset drive has not been installed or a lot of the time it's the sd card reader driver.

base system devices are usually things like card readers.

Base System Device drivers are usually installed by what the manufacturer calls "Chipset" drivers. If you are running Windows XP, there is an Intel Chipset driver available at the Lenovo Support Page for your model. If you are running an Operating System other than Windows XP, I would go to the above page and compare the drivers listed there with what you are seeing in Device Manager. Install the ones that are missing. Hope this helps!

INSTALL THE CARD READER DRIVER

Base system device is normally the chipset utility

"Base System Device" is your card reader, I had the same problem. If you dont use it jst disable the device, otherwise the drivers should be on your alienware Master CD, if not get a tech support guy to send 'em to you.

you need the ricoh chipset drivers
