Part No:MN-096-2C1-41 Rev:1.21ForewordForewordThank you for purchasing the AB-PX5/AX5/TX5 as the heart of your computer’s system.We hope this instruction booklet will enable you to install PX5/AX5/TX5 in your systemsafely and without any errors. Although you may be familiar with some of the concepts wewill explain, please read over them again to avoid any problems.1.
