3.3 Update System BIOS Menu
This submenu under the Main menu provides information about the current system firmware, settings, these control
updates, the ability to check for updates over the internet or on the local network, and the ability to update system firmware
from a FAT 32 partition on the hard drive, or a USB disk-on-key.
For the BIOS flash to succeed, do not remove power or turn off the system during any phase of the process. The following
description of the BIOS flash phases helps you avoid interrupting the process. The BIOS flash proceeds in four phases:
1. The system displays a progress bar. When progress is 100%, the system reboots. This is the initial BIOS flash.
Because the system must reset power completely, there might be a delay of between 10 and 15 seconds before
power returns to the system.
2. The screen may be black initially and an LED may be and blink. This will occur only if the boot block needs to be
updated. On some models, video cannot be displayed during this phase, so the beep/blink code indicates that the
system BIOS is flashing normally. Other models may display ‘Step 2 of the BIOS update is in progress’ during this
phase. The computer will reboot again, and this might also take 10 to 15 seconds to complete.
3. The message “Final step of the BIOS update is in progress” is displayed.
4. The screen is black for a short period, and then the OS starts. The BIOS update is now complete.
