Hey ... so I looked through the docs, and I agree that it "should" be an option, based on the information available. The BIOS release notes is where I got the revision information: ftp.dell.com/.../PE840-BIOSA08.TXT I have never actually seen an 840 labeled specifically as "II", so I don't know if they are so rare or market-specific (for example, there exists an almost mythical 2850 II that supports DC procs and VT, I believe it was released only in European markets) that there aren't many around, or if it is the first revision that is so rare that nearly all 840's are II's, so the distinction is rarely made.  There are 3 revisions of the 2950 (which do show the revision in OMSA - maybe the 840 does not), with progressively different specs - FSB, memory max, processor support, internal USB/TPM, etc.  The 840 BIOS does indicate a revision II of the 840, but like you said, I believe the point is almost moot, as you seem to have the latest/greatest revision. You might think about installing Hyper-V as a test to see if it is active.  VT, for example, I have seen enabled with a supporting processor is installed, even if the system's BIOS does not have the option to explicitly enable it.
Hello, I have a PowerEdge 840 on which I am looking to do a little Hyper-V work.  In preparation for this I’ve recently upgraded the CPU from the original Pentium D 3.0GHz (no Virtualization Technology support) to a Xeon x3210 which does support VT.  The new chip is installed and working fine.  Before the chip swap I updated the BIOS from A03 to the latest, A08.  When I go into the BIOS, I can find and enable VT, however there is no BIOS setting for XD (Execute Disable).  If I look at the CPU information under Dell OpenManage, it says the CPU is not XD capable and XD is not enabled.  I’ve tripled checked the BIOS settings and there is no XD enable setting.  Just for the heck of it I reflashed the A08 BIOS after the Xeon chip install – no change. So, I’m puzzled – I’ve seen Dell documentation that says the PE840 with Xeon processor supports Hyper-V. I’ve seen Dell documentation that says PE840 BIOS version A02 and later support XD. Intel clearly says the x3210 supports both VT and XD. I’ve seen multiple accounts on the web of people running Hyper-V on Xeon equipped PE840s.   What am I missing?  Does this version of BIOS bundle the XD setting within the VT setting?  Is OpenManage lying?  Is there a separate BIOS download for Xeon equipped PE840s?  (I pulled down the A08 BIOS associated with the Dell service tag which of course corresponds to a system originally equipped with the Pentium D). I would greatly appreciate your input on this. Thank You,
PowerEdge 840 BIOS XD (Execute Disable) Setting ?
