There is a minimum BIOS version, although without looking it up, I couldn't tell you what it is.  Make sure your BIOS, ESM, and PERC firmware is up to date.   Are you having problems installing the OS (Server 2008R2), or are you having problems enabling Hyper-V after the install?
Hi, Would like to find out whether Dell PowerEdge T110 (purchased somewhere end of year 2010) with Intel Xeon X3430 able to install Microsoft Windows Server 2008 R2 with Hyper-V? I've tried to enable 'Execute Disable' and 'Virtualization Technology' but doesn't luck doesn't seems fall on me. May I know whether is there any other requirements, such as Bios version, other settings to be done etc.? Thanks in advance and hope to hear real soon. Regards
