[Help] "Still waiting for boot device" after motherboard change

Well yesterday I changed my motherboard from a EP45-DS3LR (with Mac Bios) apparently faulty to a P5Q-E.


Before that I changed the Extra folder with a dsdt took from a user of this forum and the kexts he was using.


I made this change (knowing it would have been worse compatibility talking) cause I bought an Agility 3 (which still has to be delivered to me btw) and I wanted to buy a Sata 3 card to fully use it (Asmedia 1016 chipset). And for that I needed a PCI Express 2.0 bus (5gbps of the 6 which sata 3 has) and not an 1.0 which would have had 2.5gbps, even less than Sata 2...


Anyway I set the HDD in ACHI mode in the BIOS and on boot they are recognized and everything... but I constantly get the error in the title.

I tired disabling ACHI, using rd=disk (even if I put a random number for the disk number cause I didn't have an idea which to use xD), safe mode and everything without any success.


I even made a new installation of Chameleon on a USB flash drive trying to delete the dsdt, change Kexts and stuff like that, but it didn't work not even like that.


What do you suggest me?
