Hi, I'm trying to install ESXi on this system and I'm stuck with this issue "Multiboot could not setup video subsystem" Someone told me to install external video card with DVI. I tried with PowerColor 7850 and I couldn't get it work. It doesn't detect at all. I think it's too powerfull or something else. I will try with ATI 4890 which got VGA also.
I've worked it out. You have to reset the BIOS using pins for clearing CMOS.
