This document provides instructions for finding the host ID or disk serial number on different operating systems. It explains that the host ID can be the MAC address or disk serial number, and then gives step-by-step directions for finding the MAC address using ipconfig or ifconfig commands and the disk serial number using vol or diskutil commands on Windows, Mac OS X, Linux, and Solaris systems. It notes that dashes or colons should be removed from MAC addresses when using them with Maple products.
