    Check your computer's hardware. In order to run this crack, you will need the IPW3945 chipset. To find out if your computer possesses the chipset, open the command line by clicking Start and then entering CMD into the Search or Run box. Once you have access to the command line, type "ipconfig /all". Look for "Intel PRO/Wireless 3945ABG Network Connection". This is a common chipset on many laptops.

    Set your computer to boot from CD. In order to use WiFiSlax, you will need to make sure that your computer can boot from the CD drive. TO do this, reboot the computer and open the BIOS menu. You can access the BIOS menu when you see the computer manufacturer's logo. The key you need to press will be displayed on the screen. It is typically F2, F10, F12 or Del.
    1. In the BIOS screen, navigate to the Boot menu. Set the first boot device as the CD/DVD drive. This is sometimes labeled as an optical drive. Setting it first will make the computer try to boot from the CD before it loads the operating system from the hard drive like it normally would.
