Making this so developer of Quibble be aware this issue.

Intel [Silvermont] -based [Bay Trail] / [Cherry Trail] Tablets have 32bit UEFI bios while CPU is 64bit.

Devices like:
Acer NP15A
Multilaser M8W tablet
Asus T100
Lenovo Tab2
Lark 7i win (- I can test)
Alcatel plus 10 (- I can test) (running ubuntu 64bit via grub blob)

Here on github you can find project
"EFI boot blob and build scripts for devices using IA32 UEFI" aka "bootia32-efi" or "bootia32-efi AsusT100"
You have also superuser tutorial with I386-Grub-efi as "[Installing Windows x64 on 32-bit UEFI (EFI-IA32) via GRUB]"

Q: Why waste time?
A: The grub way not always work and i find this quibble project so i suggests. Also I was dissapointed that devices i have are 64bit but BIOS support only 32bit systems (bootia32.efi) in era that 64bit OS is norm.

Thank you for reply
Yes... That one is closed, and was in year 2020 when 32bit Win10 still has support and W11 not EXIST.

I will not post this IF =
Tablet i have had (legacy Bios) CSM support (witch lacks in uEFI v2.40 that runs in) IF i will be able to enable CSM, then i can run DUET + REFIND to boot EFI 64bit OS like W11.

Friend have 1st gen intel laptop with 2GB RAM that has no uEFI and he show me that he CAN boot W11 w/o problem via DUET.

I know i can use 64bit Linux with that Grub trick but i was not aware that tablet with 64bit CPU is CRIPPLED with 32bit uEFI.

Regards
