 === UEFI way (EFI system partition) ===
-On some new platforms (for example HP Envy 17 (17-j005tx) '2013) BIOS reading (backup) feature is disabled. In such case flasher will show the following error message '''IHISI: flash read error in SMI!''' and the system will hang (on some notebooks you might even need to unplug power and remove battery to shutdown system).

 It doesn't seem to depend on Windows version or type (x64/x86), even WinPE recovery disks won't help.
-However in most such cases flasher won't update BIOS directly, but will use UEFI BIOS update procedure (after rebooting). New BIOS is copied (in unencrypted form) to UEFI partition, so we just need to find it there.

 You might want to run this command from some console file manager (like FAR, http://farmanager.com/) or run your file manager side-by-side under Administrator account, since X: disk won't be visible/accessible otherwise.
