Abstract
Various embodiments disclosed herein are directed to gaming devices having a secured basic input/output system (BIOS) and methods for determining the validity of the gaming device's BIOS. According to one embodiment, the gaming device includes a secured module for authenticating the BIOS of the gaming device. During the boot-up process, the secured module issues a challenge to the BIOS. The BIOS generates a response to the challenge, and the secured module determines whether the BIOS response matches the calculated response of the secured module. If the BIOS response matches the secured module response, the gaming device continues the boot process. Otherwise, the boot process is halted by the gaming device.
