What happened with Unibeast??
It got stucked on the previous screen shot I posted : PCI configuration begin.
Unfortunately I have only one USB stick and it is now "clover made" with the issue posted above.
By the way can I do a USB install drive on a regular USB HD instead of USB stick ?
Ok, as I like to play around with those toys I tried the options you suggested on unbeast :
dart=0 npci=0x2000 -f -v :

dart=0 npci=0x3000 -f -v :
View attachment 135349
Obviously it went a bit further.
This time as I had problems to boot on the USB stick (with BIOS message saying that I had to load default settings...), I changed also the HD for installation : before I kept the former windows SSD system disk (IBM) for another SSD I have (samsung 840), with that change it boots more easily.
I have no folder on my unibeast usb stick... Only Install OS X Yosemite.app and MultiBeast.app... No Extra/Extensions folder. Did I miss something ? I used this procedure.
chflags unhidden /Volumes/[B]<Your USB Name>[/B]/Extra
It will be hidden. Run the below command to make it visible.
Code:chflags unhidden /Volumes/[B]<Your USB Name>[/B]/Extra
