 I've flashed the new version of firmware (ca. 2019) from
 https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-twist-series-laptops/thinkpad-twist-s230u/3347/downloads/driver-list/component?name=BIOS%2FUEFI
 .
 
 Unfortunately, the problem persists even after a successful firmware
 update.  I suppose a workaround could be hacked-around.  However, if
 the machine is left in BIOS-only mode (not just UEFI + legacy
 support), then it successfully boots with a basic gpt biosboot -A ...
 and installboot ... setup.  Thus, I doubt that whatever workaround
 would be worth the effort.
 
 May I suggest, as an option, an ability to build more than one flavor
 of the bootable efi binary?
