Have anyone ever tested Windows 8 touch control on EEPCv7 pre-boot authentication?
In order to use it on pre-boot, it seems that we need to enable "Enable on screen keyboard" policy at least, but I just would like to know if EEPCv7 can relly handle Windows 8 touch control.
To begin with, EEPCv7 doesn't support it...?
Yes, It will work, thats for sure, please have a look on it.
This option enables the Pre‑Boot On‑Screen Keyboard (OSK)
and the associated Wacom serial pen driver. When this option
is enabled, the pen driver finds a supported pen hardware
(Panasonic CF‑H1 and Samsung Slate 7) and displays the
If you do not select this option, the BIOS will use mouse
emulation. In such a situation, the BIOS will treat the
digitizer as a standard mouse, which might lead to the
cursor being out of sync with the stylus on USB connected
Wacom pen digitizers.
Always display on screen keyboard — Forces the Pre‑Boot to always
display a clickable on‑screen keyboard regardless of
whether the pen driver finds suitable hardware or not.
Make sure to note that this is only valid for BIOS based
hardware. On UEFI, we should note that the digitizer is
managed by the UEFI software, so the UEFI
implementation needs to contain drivers for the digitizer.
You may give it a try and I belive you will get the maximum.on 2/8/13 8:59:24 AM CST
Alex, you are thinking of EEPC5 on a BIOS PC, TK45 is talking about EEPC7 on a uEFI enabled device - a totally different piece of software.
The answer is, EEPC7 on uEFI uses the uEFI OS to provide support for all the devices, so the vendor of the device must provide either the Simple Pointer Protocol or the Absolute Pointer Protocol.
Thank you for your explanations.
So, before installing EEPC to the PC, I always have to ask it to PC vender if the device of PC provides these protocols, right?
