I've got this motherboard and I'm trying to get it working with ESXI 5.5. So far I've tested couple images with custom drivers for the LSI 9240-4i controller, but none of them have worked. In some youtube video it's said that I've got to change some option to EFI compatible ROM, but excuse me I can't find it NOWHERE! Absolutely nowhere! Please help me, please.

Can you do a straight AHCI install?
