I'm using the latest BackTrack ISO release for security analysis. BackTrack is basically a configured Ubuntu distro. However, I'm missing my wireless card driver (Broadcom 4313). There are several forum posts on the site explaining how to upgrade the kernel and install the drivers. However, I use the ISO file from a USB drive as a "Live CD" (i.e., no installation) and can therefore not tchange the original ISO.
My question is: how can I take an ISO file (any, for this matter), update its contents and repackage it to a new ISO that can be live-mounted? is there a procedure for this? Do I need to use a virtual machine?
