Warning:
Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction.
What is a BETA?
BETA describes a new version that is reliable yet may not include all the features of the final product. During this phase we are previewing new features and gathering customer input to insure our product provides the best experience possible.
