Re: Just installed Windows XP on my Inspiron 600m. Need help with drivers installation
The Mobile chipset is the primary set of chips linking your processor to all the other components in the computer - memory, drives, slots, etc. That should be installed right after the Notebook System Software.
The Smart Card controller is only, well, for the smart card reader. I guess Dell reorganized the page and just stuck it under Chipset. Don't overthink too much.
