I am helping a small non-profit install ubuntu on some (40) donated inspiron's.  To get wifi running I need to install some additional packages:      b43-fwcutter firmware-b43-installer. I would like to create an install CD or USB stick that does not require a wired internet connection.  Unfortunately, the firmware-b43-installer seems to access the internet as part of its installation.  So even if I can figure out how to add these two packages to the install CD, I'm not sure this will help.Anyone have an idea how I can accomplish this.  Thanks.
