I have a rare intel chipset based WeTab Tablet PC (actually a laptop-inside with a screen on top), it is actually similar to the ExoPC so it is possible to flash the more friendly ExoPC BIOS with boot posibilities. The specs of the device: https://en.wikipedia.org/wiki/WeTab
However, this is a device from around 2011 and the software is really buggy and unsupported (based upon Meego Linux) and the root utility (RootShell) cannot be installed via the WeMarket app-store anymore. So it is not possible to get root access on the thing to be able to boot from USB drive to flash another BIOS.
The SSD inside this thing is replacable, so I removed the 16GB sandisk mSATA drive and replace it temporarily with an USB adapter (see below) however the EFI BIOS shows an error.
Adapter I use:
EFI Shell version 2.00 [4.640] Current running mode: 1.1.2 map: Can not find required map name. Press ESC in x seconds to skip startup.nsh, any other key to continue. Shell> _
This error is because the EFI-partion is on the original drive. I cannot press any key at startup (USB keyboard doesn't work), can't do anything.
Came up with the idea to clone the EFI partition on an USB drive, create another bootable partition with the BIOS update utility and flash it. After flashing the BIOS, copy the EFI partion to the original drive and replace the temp drive with the original and boot from USB to install another OS.
The question is, is this possible anyway because I don't have a mSata to SATA adapter and need to purchase it but is it worth to do so. Does my plan going to work anyway.
Maybe there is another way to get root access to the thing, any ideas?
