Combo Card – refers to Wireless and Bluetooth:
There are 2 variant for HCL 1044 using Intel and Non-intel combo card. A intel combo card require separate installation of wireless and bluetooth which mean you need to install them one at a time. For non-intel HCL already provide the wireless and Bluetooth driver in one driver packages. so you need to choose base on your specification. If you does not know how to check, just test which work for you.
