So I have booted up via CD and the installation asks whether to setup the PATA disk as EFI for BIOS. I have used 's method to patch the FreeBSD 12 ISO so that it has MBR boot only, and so the MacPro does boot the CD installer using BIOS legacy mode.
This leads to all sorts of heat issues where other people on the net experience the CPUs halting to protect themselves.įor obvious reasons, I would much prefer to get EFI boot happening. I'm wondering if anyone is able to offer some suggestions:Ģ x QuadCore Xeon 64bit CPUs (have been upgraded)Īnytime the Mac boots using Legacy BIOS and not EFI, only 4 SATA ports are recognised, temperature sensors (and thus fan control) are not presented to the kernel correctly to be controlled.
