You can try this, format one Sata Hd in HFS+ (GUID) and restore your lEO1 into the NEW (sata) LEO2, download the new Medevil AppleNforceAta.kext and and copy this kext into your second leo /system/library/extensions. Extract the pc_efi_v80 in your desktop (LEO1), with diskutility get info about your LEO2 (diskXsY) and unmount the disk open a terminal and type:

(for example the device is disk1s2 ok?)
sudo -s

(your password)
cd /Users/"Your user here"/Desktop/pc_efi_v80

./startupfiletool /dev/rdisk1 ./boot_v80

dd if=./guid/boot1h of=/dev/rdisk1s2 bs=512 count=1
dd if=./guid/boot0 of=/dev/disk1 bs=400 count=1

-At this moment you will see the leo2 mounted again in your desktop-
don´t close the terminal, copy the applesmbios from your pc_efi_v80 into LEO2 /system/library/extensions

in the terminal type again

cd /volumes/"LEO2"/system/library/extensions
chmod -R 755 * && chown -R root:wheel *
cd ..
rm extension.mkext
kextcache -a i386 -e

close the terminal, open diskutility and verify the LEO2 and repair the permission, reboot into LEO2 (put the correct device in your bios or you can use the bios bootloader f8-10-12 I don´t know what is your mother) and cross your fingers!!
