Have VMWare ESXi VM hardware look like the underlying hardware

Had an issue today where I couldn’t use the IBM OEM Windows 2012R2 media that IBM provided together with our new xServer because the media running in the ESXi VM didn’t see the underlying IBM hardware. The solution was to set an ESXi option on the VM called SMBIOS.reflectHost = “TRUE” as described in this post (Unable to install Microsoft Windows Server 2012 on VMware ESXi host – IBM System x). That made the VM represent the underlying hardware.
