Latest Chuwi Hi8 Pro BIOS (D2D3_Hi8Pro.230_0510). Is it really 64 bit ?

Yesterday I flashed the latest BIOS for my Hi8 Pro  and noticed something unusual. When I booted into BIOS, the Project Version was showing as D2D3_Hi8Pro.230_0510 x64. Notice the x64 suffix at the end. It means that the BIOS is 64 bit capable. To confirm this I created a 64 bit Windows 10 USB installer and tried to boot from it. As I expected, the tablet recognized my pen drive but it crashed at the setup screen and showed me ACPI_BIOS_ERROR.

Then it automatically restarted and booted back to the pre-installed Windows 10 OS. I rebooted the tab and went to BIOS again. But this time I was surprised to see that the Project Version was showing just D2D3_Hi8Pro.230_0510. That x64 suffix was no longer there.

After experimenting  a few more time I found another strange thing. If I boot into Android and then reboot back to BIOS, it will show Project Version as D2D3_Hi8Pro.230_0510 x64 . On the other hand, if I boot into Windows and then reboot back to BIOS, it will show Project Version as just D2D3_Hi8Pro.230_0510.

So, does it means that Android is using 64 bit BIOS ?

From what i can gather, the processor is x64 capable but 64bit os’s were not used in the hi8pro due to its limited memory.  ive seen posts here about ppl building their own win64bit installs but then having to get 64bit drivers together. http://techtablets.com/forum/topic/drivesr-for-windows-x64-is-here/

my android lacks <span style=”line-height: 1.5;”>ro.product.cpu.abilist64 as per here to see if ur running a 64bit A.OS. </span>

Ok, I’ll check that. B/w what is your BIOS version ?
