Hiya LoshieIT,
I'm running into the same problems with the HP ML110 G7 with the E3-1220 Xeon. I also get the Pink Screen during the boot process.
I've made sure that the various BIOS settings are set (Intel VT, ) and for the SATA I've moved it to AHCI mode. I even removed the HP SmartArray P212.
HP ML110 G7
ProLiant System BIOS - J01 (05/20/2011)
Proc 1: Intel(R) Xeon(R) CPU E31220 @ 3.10Ghz
HP Power Profile Mode: Maximum Performance
Power Regulator Mode: HP Static High Performance Mode
No-Execute Memory Protection: Enabled
Intel(R) Virtualization Technology: Enabled
Processor Core Disable: All Cores Enabled
Intel(R) Turbo Boost Technology: Enabled
Intel(R) VT-d: Enabled
So far no luck, I will keep you updated if I make any progress.
