Are there ANY versions of x86 RouterOS 6.x which will work natively (i.e., without resorting to installing it within a hypervisor, or any other janky work-arounds) on a PC with no legacy mode available in BIOS, only UEFI? I see that UEFI is supported in 7.1+, but I can't find anything about any versions of 6.x supporting UEFI.
