I have been trying for a long while to install on my Compaq EVO 620c a OSX86 Hackintosh.
I am now trying the Leopard version of Kalaway.
the system whould not boot so i got to the point were i seeked and found a good solution
boot from the dvd and press f8. then type -s
when it finises loading type:

fdisk -e /dev/rdisk0
flag 1 (your partition number)
write
update
quit
reboot

This solved the reboot problem i had with my system and the computer can now start debug proces.
I am still having a few issues but i am dedicated on solving them.
Hope to update soon.
