Indeed, the first laptop seems to have 32-bit UEFI firmware which is a very rare case nowadays. Most UEFI machines, including mine, are 64-bit, that is why there is only BOOTX64.EFI so far.
I just checked that fasm can produce PE EFI binaries (not only PE64 EFI), and QEMU can emulate UEFI32 environment (using edk2_ovmf firmware), so I hope to come back with BOOTIA32.EFI loader this weekend.

In short, nobody expected to see UEFI32 firmware.

Which logo? Try
this image, is there any text output during boot?

Yes, this is a strange device with a 64-bit processor and a 32-bit BIOS.
: For example some people manage to run 64-bit Linux on it. Using special UEFI as it: https://github.com/hirotakaster/baytail-bootia32.efi
Well I'll try not to forget to check this update.
When I'm try to run this image and it not work, loading is freezed with bios logo. (I'm think KolibriOS kernel not loaded or not finded).

Evgeniy,
- Try this image on both laptops.
- Do you see any text message?
- If yes, try this image.

There is no need to run loaders manually. Select the flash as the boot media and UEFI firmware will find and run appropriate boot*.efi loader itself depending on the architecture.

I don't understand which laptop corresponds to each log. Could you write like this:
Code: Select all
Image1:
Log from latop1:
blah
Log from laptop2:
blah
Image2:
Log from latop1:
blah
...
blah
Log from laptop2:
blah
...
blah

I'm not sure if this option is in the BIOS, but I'll try.
Image1:
Log from 32x latop1:
uefi32kos loaded
Image2:
Log from 32x laptop1:
uefi32kos loaded
load kernel
load ramdisk
...

I decided not to experiment on the 64x laptop yet, because I'm worried about its condition.
I hope this won't hurt a 32-bit laptop either.

It still can be yes and no, let's
check again.
Please, provide text output starting from 'Locate GOP handlers'.

Seems like the second GOP handler works.
Let's see what fails next:
