I have 3 Dell R730s Im trying to configure for Grid K1 cards. Per the grid deployment guide, it says to disable the Memory Mapped I/O above 4GB setting. When I do that, all 3 servers boot up to an error UEFI0134: unable to allocate Memory mapped I/O… and it tells me to re-enable that setting. The system BIOS is up to date. Is there some other step?
