Hi, is it possible to add support for x64 on this tablet?
BIOS
This is the bios for the first batch of Hi8 Pro, these only came with Windows x86 with no option to dualboot to Android.
Just in case anyone thinks I'm dumb it has an Intel Atom X5-Z8300.
This device would be almost perfect if there was a bios update with support for x64 and the launcher to select Android or Windows, but Chuwi released the dualboot Hi8 Pro that is a different hardware revision and its bios is incompatible with the singleboot.
I looked over the bios and didn't see any kind of "enable/disable" 64bit, have you attempted to install 64bit Windows on the device?
No it can't boot anything x64.
I am now using an "experimental" bios that I had to flash with an spi programmer, it is now dualboot and the bios has a switch for IA32 or x64 but it can't boot 64-bit Windows installation.
