I have an Arima NM46X dual Opteron server that I am attempting to install ESXi 5.1 on. During the loading of the installer, I am receiving the below message:
VMware ESXi 5.1.0 (WMKernel Release Build 799733) The system has found a problem on your machine and cannot continue. Unsupported microcode level 0x01000039 Please use microcode patch level 0x01000065 or higher with AMD Family 10h B3 processors.
Arima appears to be out of business, and BIOS on their website for this machine is v1.08. The server is currently running v1.10.
Has anyone run into this issue or have any suggestions?
