Session Agenda
Designed to address BIOS Limitations
• Needed for the larger server platforms (Intel-HP Itanium)
• First called Intel Boot Initiative then renamed to EFI
• Specification and Source Code encouraged the UEFI forum
Provides support for newer hardware
• Addresses the need to support x64 bit system
• Streamlines the boot process into the OS
• Simplifies the integration with 3rd party components
UEFI encourages industry
participation
• 11 Promoters
• 20+ Contributors
• 70+ Adopters
Divided by working groups
• USWFG
• UTWG
• PIWG
• ICWG

Looks and feels like a regular shutdown / boot
Leverages Hibernate technology to cache the core system
Enabled by default
Delivers considerable improvements:
• Boots more than twice as fast on SSD-based netbooks, including POST
• Need partners to continue work to reduce POST times
Can you really tell the difference?
• Native boot: 40 seconds (to initial MDT wizard)
• Native boot: 40 seconds (to initial MDT wizard)

Secure Boot Process
Secure boot is a UEFI specification, not a Microsoft product!

•
Only executes signed UEFI binary
images
Includes Option ROMs, pre-boot
utilities and OS loaders.
Benefit: Helps prevent malicious
code before the OS loads
Benefit: Provides Time-authenticated
variables
Benefit: Allows stronger keys for
encryption

Early Launch Anti-Malware (ELAM)
Windows 7
• Malware is able to start before Windows and Anti-malware
Windows 8
• Trusted Boot starts Anti-Malware early in the boot process
Windows Support for UEFI
Current Windows-Specific UEFI Highlights
• Multicast Deployment
• Fast boot and resume from hibernation
Future UEFI Capabilities
• Rootkit prevention
• Network Authentication
