4.11 Intel® Fast Flash Standby™ / Rapid Start Technology™
The target of Intel® Fast Flash Standby™ (iFFS) (also known as Intel® Rapid Start Technology™ iRST) is to get a wake-up
time from S4 compareable to S3. Normally S4 is caused by OS which stores it's information to the hard disk and does then
a normal shutdown. S4 resume takes quite long as the system does a normal BIOS POST and OS restores it's information
from the hard disk.
IFFS does it in a different way. The Operating System initiates an S3 and stores it's information in memory. After that
BIOS copies this OS information from DRAM to SSD and does a sleep state similar to S4 with nearly zero power. If system is
resumed by power button, BIOS restores memory content from SSD to the DRAM and does an S3 resume which is much
faster.
Requirements
» SATA Solid State Disk in AHCI mode
» Free disk space on the SSD with at least the DRAM size
» Operating System with disk partition tool to allocate the hibernation partition (e.g. Windows 7/8)
» BIOS supporting iFFS feature
How to setup once the operating system is installed
» Prepare a free disk space on your onboard or external SSD with at least the size of DRAM
» Open cmd.exe in Administrator Mode and type diskpart.exe to open the Windows disk partition tool
» DISKPART> list disk
» DISKPART> select disk X (X is disk number where you want to create the store partition. Refer to results from “list
disk” for exact disk number)
» DISKPART> create partition primary
» DISKPART> detail disk
» DISKPART> select Volume X (X is Volume of your store partition. Refer to results from “detail disk” for exact volume
number)
» DISKPART> set id=84 override (ID 84 marks the partition as hibernate partition)
» DISKPART> exit
» Now there should be a Hibernate Partition visible in your disk management
» Reboot and enable iFFS in BIOS
Usage
» Activate Lid / move system to Sleep/Standby ( S3) →
» After configured period of time in Setup the system powers on automatically and information in DRAM moves to
non-volatile memory (Default is 'immediately')
» System switches off again to iFFS ( comparable to S4, Power Supply can now be disconnected) →
» When System is powered on, information moved back to DRAM (No display output during copy process)
» System resumes same as Sleep/Standby S3
Note
» Depending on the platform iFFS enabled may disable the hibernate function in Windows automatically
