+BIOS updates are actually done via the hidden `HP_TOOLS` service partition which
+you can get to by pressing <kbd>F2</kbd> after switching on the notebook or from
+the *Startup Menu*. The update you download from the hp service page merely
+copies the new BIOS files to that partition.
+
+![]({{ site.url }}/assets/hp-startup-menu.jpg 'Startup Menu'){: width="400px"}
+
+However, if you deleted that partition or switched to Linux for your operating
+system, things get a little bit complicated.
+
+
+Hidden partition deleted
+========================
+
+So you deleted the hidden `HP_TOOLS` partition when setting up your new
+operating system. The only effect you'll notice is that the *System Diagnostics*
+option in the BIOS (<kbd>F2</kbd>) will look a bit dull:
+
+![]({{ site.url }}/assets/hp-system-diags-internal.jpg 'Hardware Diagnostics'){: width="400px"}
+
+But don't worry, this can easily be fixed. You only need a spare USB flash
+drive and a Windows 7 (or newer) VM or PC. Then do this:
+
+1. Download [HP PC Hardware Diagnostics](http://h41336.www4.hp.com/go_techcenter_pcdiags)
+   from the hp support page (first item, ~23 MiB, formerly known as *HP UEFI
+   Support Environment*)
+1. Run your Windows 7+ VM or get to a Windows 7+ PC.
+1. Plug in the empty flash drive (or connect it to your VM).
+1. Run the downloaded installer and choose to **Install to USB**.
+
+That's it. You now have a `HP_TOOLS` flash drive which contains the same as the
+hidden partition you deleted. And this includes a tool to update your BIOS
+firmware.
+
+You can check if everything went correctly by plugging the flash drive to your
+Spectre, rebooting and pressing <kbd>F2</kbd> before the operating system loads.
+
+Now, the *System Diagnostics* should look way different:
+
+![]({{ site.url }}/assets/hp-system-diags-tools.jpg 'Hardware Diagnostics from HP_TOOLS'){: width="400px"}
+
+
+Updating the BIOS firmware
+==========================
+
+Now to the actual updating of the BIOS firmware. Of course, you first have to
+download the BIOS firmware from the [Spectre's support page](http://support.hp.com/gb-en/drivers/selfservice/hp-spectre-13-4100-x360-convertible-pc/8499273/model/8902244).
+
+Find a PC (or VM) with Windows XP (or newer) and proceed as follows:
+
+1. Plug the flash drive to the Windows machine.
+1. Run the downloaded installer and select the *Install to USB stick* option
+   when asked.
+1. Eject the flash drive and plug it into your Spectre.
+1. Switch on the Spectre and press <kbd>F2</kbd> a few times until you end up
+   in the *HP PC Hardware Diagnostics UEFI* tool.
+1. Click on ***Firmware Management***.
+
+Now you should be seeing this screen:
+
+![]({{ site.url }}/assets/hp-bios-update.jpg 'Firmware Management'){: width="400px"}
+
+Click on *BIOS Update*, confirm that you really want to update the BIOS and
+that the new version is newer than your current one. Then just wait for it to
+finish and the Spectre to boot up again.
+
+
+No Windows available
+====================
+
+In the case there's no Windows VM or PC available to you whatsoever, you could
+try unpacking the installers manually.
+
+
+HP PC Hardware Diagnostics
+--------------------------
+
+First, use `7za` to unpack the downloaded `SP123456.exe` file. This will give you
+a `setup.exe` from that package, because hp wraps the actual installer in another
+file.
+
+With that `setup.exe`, you can run `wine setup.exe /a` to run it in *admin* mode.
+(See [here](http://stackoverflow.com/questions/8681252/programmatically-extract-contents-of-installshield-setup-exe).)
+Select your language and watch the *Extracting HP PC Hardware Diagnostics UEFI.msi*
+progress bar. Now the important part: **As soon as the dialog finishes**, press
+<kbd>Ctrl</kbd>+<kbd>C</kbd> to abort the process so the installer doesn't
+delete its temporary folder again. 
+
+Now search the windows temp folders for some folder like `{15EC3F6C-EA46-43B7-9B8A-132F011C1436}`
+(differs each time). This could be in `~/.wine/drive_c/windows/temp/` or
+`~/.wine/profile/Local Settings/Temp/`. In there, you'll find a file `HP PC Hardware Diagnostics UEFI.msi`.
+
+This can be unpacked with `7z x "HP PC Hardware Diagnostics UEFI.msi"` (`7za`
+won't work!), but it won't restore the proper file names. Luckily, there's also
+a `Data1.cab` in there, which you can extract with `cabextract Data1.cab`. This
+one contains the proper filenames.
+
+Now, on your empty *vfat* formatted flash drive, create the following directory
+structure:
+
+* Hewlett-Packard
+  * BIOS
+    * Current
+    * New
+    * Previous
+  * BIOSUpdate
+  * SystemDiags
+
+(Yes, that's a `Hewlett-Packard` directory in the root folder, `BIOS`, `BIOSUpdate`
+and `SystemDiags` below that and `Current`, `New` and `Previous` below the `BIOS`
+directory.)
+
+From the extracted files, copy `CryptRSA.efi` and `CryptRSA32.efi` to `BIOSUPdate`
+*and* `SystemDiags`. Copy all the `HPBios*` files to the `BIOSUpdate` directory
+and all `HPSysDiags*` and `SystemDiags*` files go to the `SystemDiags` dir.
+
+This should be sufficient to make it work. (No guarantees!)
+
+
+BIOS Firmware
+-------------
+
+Here, you can unpack the installer from the `SP123456.exe` with `7za`. But
+I can't find a way to unpack the extracted installer file as this seems to be
+some custom application. Also it uses some specific driver (probably to access
+the BIOS) which breaks wine.
+
+So for this, you'd definitely need access to some Windows XP (or newer) PC or
+VM. However, since you already have the prepared flash drive, it's only a matter
+of plugging that in, running the installer and selecting the *Install to USB
+stick* option.
+
+You can also use the *Advanced* option to extract the BIOS files to a separate
+directory and copy those manually onto your flash drive to this directory:
+
+    Hewlett-Packard/BIOS/New/
+
+The files are named `0802D.*`, `08035.*`, `0804E.*` and `0804F.*`. Each as
+`*.bin` and `*.sig`.
