This is the most recent UEFI32 work-around procedure, as the old tutorials and guides get out of date fairly quickly. Here is another version for the Asus T100TA.
The main reason to support UEFI32 is that many of these old baytrails can't practically run Windows 10 anymore, but they are still fast enough for browsing, youtube, doc editing and email. Asus, Lenovo, Toshiba (and others) mass produced these win8.1/32 bit OS machines and they are ready for a second life with Linux. Fully loaded Linuxes barely run on 2GB of RAM, but there are still many desktops, WM, etc that run fine on these older machines whether in 32 bit or 64 bit. Grub install will work if the i386-efi folder is present and the liveUSB will boot if there is a suitable bootia32.efi present. That only leaves the efi detect function in grub.cfg (liveUSB) which used to work until around the 19 series Manjaro ISOs. The workaround above addresses that problem.
Do these baytrail machines truly need a rolling release distro? It depends on the priorities. For broader market share purposes - yes,
don't ignore a large base of older machines. Pragmatically, maybe not.
An external USB keyboard was needed for my T100CHI with a weird bluetooth OEM keyboard. But the T100CHI is just one of many Asus T100 models. The other T100s don't need an external keyboard/mouse for installation (or grub selections.) Driver issues are less common with recent kernels than they used to be and most can be resolved with a web search except for the camera.
(I'd add Sparky to that list)
It's hard to argue this point. The list used to be a lot longer, including Ubuntu 16.10. But most distros with a kernel 4.16 or newer can be modified to at least boot by adding bootia32.efi and the i386-efi folder to the liveUSB and it will have respectable baytrail support. A kernel 5.3 or newer is even better. Baytrail fixes and support are still be added to the kernels even into 5.8.
