Updated Lenovo BIOS to ver 2.08

Checked current BIOS version with command: 'dmidecode' under Ubuntu.
The Lenovo BIOS flash utility is a Windows executable. Since my laptop is dual booting I could use Windows to update the BIOS.
After flashing the BIOS you have to enter the BIOS and set GRUB back as the first bootloader. Initially it is only booting Windows.
You have to change it. Now it is running under:

Version: 9DCN28WW(2.08)
Date:10/14/2014
Bios Revision: 1.40
Firmware Revision: 2.40

The Elantech mouse pad with 2 finger scrolling is still working.

Title:
  Elantech touchpad without multi-touch Ubuntu 14.04.1

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On my Lenovo B50-70 laptop there is a Elantech touchpad installed.
  It is working perfectly as a mouse but scrolling, multi-touch, 2 finger gestures are not working.
  Many people are reporting this for older kernels. I would like to report this for: Ubuntu 14.04.1 LTS.

  Kernel: 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
  Ubuntu 3.13.0-45.74-generic 3.13.11-ckt13

  There are many workarounds posted like the one below.
  It is a kind of bypass using dkms and dynamically add a module.
  Some users reporting that the dynamic module does not survive a reboot. This is "fixed" by adding the remove of the psmouse and adding the new psmouse module. The code seems to work perfectly, never the less.

  I am wondering if there is a permanent solution in one of the next kernel and would like to provide you information.
  In ubuntu 14.10 (32 bit) it is working.

  I looked on the ubuntu store and found: gpointing-device-settings 1.5.1-6ubuntu2
  It has selection boxes for emulation of horizontal/vertical scrolling but it is not working.
