Boot Booster is a function of the Eee PC to allow the results of the BIOS POST to be cached in an area of the drive so it can be skipped on boot, shaving a few seconds off of boot time (and hiding the splash screen).
Here are the basic steps for activating Boot Booster if you've reformatted your primary drive and lost the “special” partition.
1. Boot GParted - I used live USB created using unetbootin 2. Launch GParted and create a partition out of the 8Mb at the end of the disk (primary partition & unformatted) 3. Note the location of this new partition - mine was /dev/sda2 4. Launch terminal and use sfdisk to change partition type
sfdisk --change-id /dev/sda 2 ef sfdisk --print-id /dev/sda 2
5. Reboot and F2 to enter BIOS to enable Boot Booster
