I had managed to install ESXi 5.1 on the specified system. Upon reboot, I got the two beeps, two beeps code. Which means video card failure. I installed a Core i3-3225 and managed to boot into bios.
The event log showed the message "Video OptionRom Authenticate Fail" Note, I am using a PCI video card, Radeon 7000.
Can anyone shed some light on this?
