Thanks Christian :-) that works now. I now understand that the last module
I have to load is ata_pthru That's great. So currently I can turn off APM
and got rid of the clunking. Next step is to make OSX load.
I'm now using
insmod hfsplus
set root=(hd0,1)
multiboot /boot
I moved 'insmod hfsplus' *before* 'insmod ata_pthru' and
changed set 'root=(hd0,1)' to 'set root=(ata0,1)'
Problem seems to be that after loading ata_pthru it
has some problems with the prefix and still wants to
/boot in (hd0,1)
I have also tried
search --file --set=root /boot
multiboot /boot
Thanks for any help
