Hi I know UEFI is on the market for quite sometime now and currently it has become a news again when MS annouce secure boot required in UEFI. Understand UEFI only support 64bit OS but as Microsoft also support ARM which in 32bit, would that mean UEFI is also supported in 32bit OS?

No support for UEFI for 32 bit systems today but in future it might change.
