Important Information
Dell Fast Boot BIOS Feature:
The Dell Windows 8 released BIOS adds a new feature that is called Fast Boot.
When upgrading from a Pre-Windows 8 released BIOS to a Windows 8 released BIOS this feature will be set in Thorough mode.
Setting this feature in minimal causes USB devices and ports to be disabled in the pre-OS environment.
If you are dependent on USB devices in the pre-OS environment this setting should remain in the Thorough mode setting.
Upgrading between Currently Released BIOS Images (Pre-Windows 8 released BIOS) and Windows 8 Feature Enhanced BIOS Images (Windows 8 released BIOS)
The new Windows 8 released BIOS contains new features and behavior, but the upgrade process for you is still unchanged.
Run the EXE application, and the BIOS handles incorporating the new features and logic with your current settings.
After the upgrade, you will immediately see that one of the visible changes is the logo screen during boot, which only displays the logo at a larger size with no other information or text.
