OS X won't boot when legacy boot is completely disabled

[dodvip123]

Hi

If i disable legacy boot completely as shown in the picture (enabled there) i can't boot os x but windows does boot (Clover bootloader).

It would be nice to disable it completely to have faster boot times and less text when loading the bios.

Verbose mode shows only the first 2 lines of os x booting. The USB installer doesn't boot either.

Does someone know if there is a fix for this? I ask this not because of the faster boot times but sometimes the bios does a hardware checkup which is time consuming.

Thanks

Generally you need to have CSM enabled. Sometimes CSM is bundled with legacy boot.

So no fix possible then in my case. Thanks!

It seems like it that disabling the onboard nic 4 and 6 and removing the Windows boot manager solves the occasional hardware checkup
