David Eliott has just released a new version of his modified boot-132 bootloader !
This new bootloader can load kexts files and boot Leopard Retail DVD!
And it is free! Plus open source!
This is definitively an open-source alternative to EFI-X!
You will need to burn a CD.
Just burn this ISO to CD : download ISO
Insert CD in your drive and boot your PC from CD
You should see a Darwin prompt
Swap the CD with Leopard Original Retail DVD
Hit Enter or type “-v” then Enter (verbose mode)
Leopard should install on your PC with no modifications to the Original DVD!
