## BIOS Update

**Warning:** This part is incomplete and you might have to do your own research about it. Nobody can guarantee that you can't make your WeTab unusuable (brick)

Download the Bios-Update-Stick-V2.zip from [pherzog's website](http://www.pherzog.net/WeTab.das-neue-BIOS-fur-das-WeTab.ashx) and apply the `.img` file inside the zip with dd to a USB Stick like that:

```
dd if=./Bios-Update-Stick-V2.img of=/dev/sdx

```

The text file in the zip describes how to boot the USB Stick, this one is a non-literal translation:

*   Have the WeTab turned on. *Also, have the WeTab connected with the charger, the USB Stick and a Keyboard.*
*   Turn it off while holding down the "Hotkey" (Upper-left, that touch-sensitive circle)
*   It should reboot after approximately five seconds.
*   Hold down the "Hotkey" and smash on F11 like it's the last thing you could do before death.
*   Select the USB Stick as boot device, follow your common sense from now on.

## Drivers

### HDMI

There's a very hacky solution for getting the HDMI-slot to work in Archlinux.

You first have to install [chrontel-wetab-rpm](https://aur.archlinux.org/packages/chrontel-wetab-rpm/) from [AUR](/index.php/AUR "AUR").

Then execute the following commands as root:

```
modprobe i2c-dev
mv /dev/i2c-0 /dev/i2c-2
tiitoo-hdmi-daemon

```

**Note:** if mv tells you that i2c-0 doesn't exist, try i2c-14 instead. It depends on the kernel.

*   When you see something on the screen you've plugged on the HDMI-port, you can kill the `tiitoo-hdmi-daemon`. But you don't have to.

*   These commands have to be executed on every booting process.

*   The graphics card in the WeTab is only capable of cloning the output of the internal screen to the HDMI-port, with the same resolution. Because of that, the driver doesn't need a running Xorg to function properly.
