ELF ERROR: real-mode bootup not supported

Post by iKnow »

I was looking foward to install Mac OS X Developer Preview 2 as i find the build incredibly interesting,
however when trying to boot up from the cd, an error occurred and PearPC 0.6 crashed.
this is what it said before it crashed:

Code: Select all

CHRP: trying to load ''
Loading ELF...
ELF: trying to load ''
ELF PT_NOTE: Name 'PowerPC'
ELF: real-mode: true
ELF: real-base: 00000000
ELF: real-size: e997a324
ELF: virt-base: 00430288
ELF: load-base: 2d000000
ELF ERROR: real-mode bootup not supported.
ELF ERROR: real-mode bootup not supported.
Does this have something to do with the boot cd?
Or did i do something wrong in my settings file?
My settings file is this:

Developer Preview 2 will not install in PearPC, you'll need to install it in QEMU.

PearPC can only boot Mac OS X 10.1-10.4 only along with some Darwin and Linux distros. Real mode boot-up, is not supported in PearPC, which is used below Mac OS X. However According to this GitHub issue, there might be a small chance that a version of PearPC can maybe boot Developer Previews or Cheetah, but we don’t know for sure :?: https://github.com/sebastianbiallas/pearpc/issues/4
