If you bought this book with a CD direct from Aleph One then it comes with technical support. Please email first, but if things get complicated than a phone call may be useful, quoting your registration code, and we will do our best to help. This service is currently focused on helping you to get ARMLinux installed and set up; queries about other aspects of Linux are probably best directed elsewhere.
The support email address is <armlinux-support@aleph1.co.uk>. The support phone number is 01223 811679.
