[Mac-on-linux-users] MOL failing to boot

[Florian F. <flo...@te...>]

Hi,

I have a small problem with MOL, and though reading lists about people havi=
ng=20
similar problems, it does not seem to help. My host is an iBook G4 running=
=20
gentoo 2.6.23-gentoo-r2 kernel modified to load the mol module=20
(handle_mm_fault symbol not exported) and mol-0.9.72.1 :

Here is my partitionning :=20

And my molrc.osx, relevant part of the configuration :

blkdev:                 /dev/hda        -boot -force -whole

startmol -X fails with  :

I have no idea why the bootloader cannot start osx within MOL, any idea is=

welcome.

Thank you very much in advance for your answer.

blkdev:                 /dev/hda3        -rw

should work.

BTW, how did you managed to compile MOL on 2.6.23 ?

Hi Elimar,

Thanks your answer.

Unfortunately not, it still fails :

Available Disks:
    HFSX  /dev/hda3                       <rw> 18949 MB

There was some problem with a missing ioctl declaration, I filled a bug rep=
ort=20
here : http://bugs.gentoo.org/show_bug.cgi?id=3D199294. The fix is not be=20
adequate according to the MOL coding styles.

Also there was a problem while loading the mol module which was=20
handle_mm_fault not being exported. I solved it patching linux/mm/memory.c =
to=20
export handle_mm_fault. Not sure it is related ?

I don't know of a working mol with 2.6.2(3|4). Did your
configuration work with kernel <=3D2.6.22?
