Installation
Prepare your computer
Before updating your computer's BIOS, Enter the current BIOS Setup Utility, and then write down each of the current settings in the event that this information is needed again after the upgrade.
Performing the update

2. From the Start menu, click Run.
3. In the Run dialog box, type: C:\Cabs\9527144\MY86510J_P03.exe. Click OK.

5. In the Software License Agreement dialog box, click Yes.
6. In the Finish and Reboot dialog box, read the information and ensure that there is a check mark for the option Yes, I want to complete the BIOS update.
7. Note the WARNING message: FOR THE NEXT 3 MINUTES DO NOT POWER OFF YOUR SYSTEM. Your system will perform an automatic shutdown and reboot process. Powering down before completion of this reboot process may cause your computer to require service by the system manufacturer.
8. Click Finish.
9. In the Warning dialog box, the message identified in Step 7 is repeated. Click OK.
10. Please wait for the process to complete the restart sequence.
11. When the computer shuts down, it may appear to take a longer period of time to restart. This is considered normal and a part of the BIOS update process.
