This laptop is basically 2 completely independent devices.
With the ability to use the LCD panel of the tablet as LCD monitor for the PC.
It is simply not possible to run 1 OS on 2 independent devices. No OS in existence can do that.
The ones you mention in the second paragraph are just 1 device (in the tablet part) that can use additional hardware contained in the base/docking-station (like keyboard, extra HDD, etc.)
This is no different than a normal laptop with extra hardware in the docking-station.
The extra hardware in the dock doesn't include CPU and/or RAM as those are in general not hot-pluggable (in Windows that is... Some other OS do have that ability.)
Even if the OS supports hot-plugging of CPU and/or RAM it would be technically next to impossible to do it in a tablet/laptop type of device.
The functionality is normally only used in virtual environments where the hyper-visor can adjust the specifications of a virtual machine "on the fly".
Doing it with physical hardware would be incredibly difficult. The electrical issues of connecting/disconnecting a CPU and/or RAM "on the fly", are extremely complicated. There exist some server-grade hardware that can do it, but it is VERY expensive stuff.
(This is not to be confused with adding/removing server-blades in a blade server. The blades are each standalone computers with their own CPU/RAM. The connection with the blade back-plane is a special bus system that is designed for hot-plugging.)
hardware protocol
must the OS support in order to achieve this. Is there any OS that is currently capable of adding CPUs and memory channels on the fly ? Can I install it on the TX201LA ?
