wyse 3040 boot mode (legacy(csm)/uefi)
I'm planning to use a Wyse 3040 as a generic linux device, because it basically is a generic x86-64 cherry trail unit. I ran in to the problem that after setting boot mode to pure uefi, strangely enough, it wont let me set it back to legacy mode. Even a restore to factory defaults, it wont show csm boot option. I've flashed latest uefi version (1.2.5), but to no avail.
No Events found!

Updating UEFI changes from CLASS 2.3.1 to Class 3.
There is NO MORE CSM and NO MORE 32 BIT with class 3.
Secure Boot must be DISABLED or OFF before legacy is allowed.
You will also have to remove any boot modes in bios AND use diskpart or some other utility to erase the disk.
Intel/microsoft/nvidia/ati etc have all abandoned legacy and 32 bit and windows 7 and 8.
Its 64 bit windows 10 from now on.
UBUNTU 18.04.3 LTS is the current supported OS for most dells and works back to machines as old as 2006 XPS 400 for example.

It seems you are confused? I'm not suggesting disabling uefi solely for the purpose of running 32bit software.
To be more precise: uefi firmware exists in both 32 and 64bit versions. The wyse 3040 has 64bit uefi firmware. A big issue on lots of cherry trail devices is even that they are sold with 32bit uefi firmware, so that , even if the cpu supports x86-64, it's about impossible to run native 64bit operating system (without nasty grub hacking tricks).
Now to make thing even more weird: the wyse linux operating system on the 3040 boots in legacy csm mode, not uefi. So yes, there is a csm boot option in the 3040 (it's factory linux os depends on it), but after enabling uefi boot mode i am not able to reactivate csm module.
as a side note: your claim on 64bit windows is false: there are still "crippled" 32bit computers being sold with 32bit uefi firmware and even the latest 1909 windows release is available in 32bit version, with bios and uefi install images.
