After doing what DarkKnight suggested and trying esxi, it worked perfectly so that narrowed it down to Unraid as the problem. So I figured out the issue finally; this started out as an Unraid v5 version that I upgraded to v6. Apparently either I missed a step doing the upgrade or it isn't in the steps but the syslinux file needed to be replaced. My version had the Xen/unRAID option as the default. This apparently disabled anything dealing with VMs when in v6. Once I replaced my syslinux file with a new version from the unraid 6 zip file it's working fine with the old e5540 processor and x5660 processor. Thanks to everyone for the suggestions and thanks DarkKnight for pushing me in that direction of trying esxi.

So more testing, flashed the BIOS even though the new BIOS was the same version. I replaced the E5540 with an X5660 which I know both are supported and loaded default settings, made sure VT-x and anything dealing with it was enabled and it still says M/B: Supermicro - X8DT3 CPU: @ Unknown HVM: Not Available IOMMU: Not Available Anyone have any other suggestions?

Yes, and it shows up correctly in the BIOS as the correct model #.

That was the first thing I did, it's running the latest. I'm thinking about getting a different CPU off ebay just to try but I bought two of the 5540's in a set since the board is dual cpu capable but I'm only running one for now. I tried both cpus (not both at the same time) and they both do the same thing. I could try both at the same time but to me I don't think that would solve it, one cpu should work just fine.

Anybody have any help with this issue? Suggestions I can try?

I just replaced my motherboard and cpu with a Supermicro X8DT3 with a single X5540 Xeon and I'm running the latest UNRAID version. Previously my system was an old AMD socket F which never supported virtualization. I have everything turned on in the BIOS dealing with VT-x and VT-d turned on that I can possible find but it still says the CPU info is @ Unknown as well as HVM and IOMMU Not available. Am I missing something simple? There isn't much left in the BIOS that I can enable. Any help is appreciated. Thanks...

Yes all three with pro keys are the same, the one I just tried was a brand new 16gb sandisk. The drive that isn't working was working fine until I formatted it and wanted to try beta6 so I'm clueless as to why this isn't working. I can format it, write data to it, etc., just can't get it to boot from it.

I checked and make_bootable.bat has syslinux.exe -maf already in it.

Sure did, it's the only thing connected to the motherboard, I don't have any hard drives connected, I'm just trying to get it to boot right now. I swap out the flash drive and it boots without issue, if I put this one flash drive in, nothing. Craziest thing I've seen in a while.

So just to add....I have a brand new flash drive, follow the exact same process, boots fine. Did the same process for the non-working flash drive, no boot. How can this one flash drive not boot properly?

I've got three unraid pro keys, I've used this one flash drive before without issues. I wanted to do a test on the beta 6 version and for the life of me can't get it to boot off the usb drive. I've followed the steps exactly multiple times, I've even tried the production version 5. I've formatted the drive from two different Windows computers, label it UNRAID, copy the files to it, run as admin the make_bootable batch file, it says it completes fine (both v5 and beta6 and on both computers both versions say completed), I put it in two different computers to boot off of; it sees the flash drive at boot up, knows to boot off of it first but then I always get the no OS found message or please insert boot disk, etc. I remove that flash drive, use one of my other flash drives that boot fine and both computers boot fine from it, it's just this one flash drive that I can't get to boot properly. Anyone have any ideas? I would think trying two different computers to make it bootable and two different computers to boot from it I would be successful at some point but I'm at a loss why it isn't working for this one flash drive. Any help is appreciated.

I was not successful in getting it to pass through using my prod 2008 hyperv server; but I've been running the free version on it for a long time and that's all I need for what I wanted to do. I don't have 2012 loaded anywhere to test but if this may be a reality of supporting hyperv in the long run then I can load one up and play around with it. You do have to force the drives you want to use in offline mode regardless so I can see where other people may have been able to get it to work by forcing the usb drive offline.

Like I said I have a working version that ddeeds compiled for me that I will share with the mods/Tom if you think you can reverse engineer it if ddeeds isn't around anymore. I also have a 2008 HyperV server that I can test with and can setup a 2012 HyperV server to test with also.

What version of unraid?

I don't use my raid card for anything on unraid other than the boot file, it's not passed through or anything. I don't even think the P400/410 cards are even seen by unraid actually. I only use the raid card for my datastores so if I lose a drive I don't lose the VM. I don't have them crossflashed or anything. I have other supermicro controller cards that pass through my drives to unraid. I don't experience any speed issues but I am running sata2 drives on that array so technically they are slow per se but I don't see it on any of my VMs running. Hope this helps...

I use an IBM 5015 card in my esxi server, but I've also used a HP P400 and P410 card as well and they all work great. You can pick up a P410 card from serversupply for like $60-$120. All of these cards support 8 hard drives and different raid versions.

I too have been looking to get the Hyper-V network driver as a standard in the unraid build. I have asked Tom and he said he would work on it when time allowed but I believe xen and the 64 bit version has taken most of his time and I didn't want to push the issue. I did however find a person on here that was kind enough to compile an old version of unraid with the hyper-v network driver and it works perfectly. His name was ddeeds who I believe has a new name but I could be wrong. Maybe if that person is still on here they would be willing to help?

I have several low wattage embedded processor motherboards, one being the asus c-60. I can tell you every instance where I've tried it with unraid it has been the worst at everything, performance, availability, etc. My e-350 and d525 atom motherboards have been better than this c-60. Writes were slow even though it has 6gb sata support, I'm talking 20-25mb. It lost connectivity all the time even during copies. This was trying different unraid versions and plain vanilla start from scratch version with new drives. I don't even think I would use this motherboard for pfsense or anything it's so unreliable. Maybe it's a bad board, maybe it's just not that great, who knows.

+1 One of the first things I did with my TAMs server was replace the PCI-X sata controllers with the SAS-MV8's. I never got to see what the old pci-x sata controllers would do I only know what the SAS versions do. I get about 68MB/s and I have a mix of 2 and 3tb drives and 24tb total.

I got the exact same thing on my install and now it's hosed. When I was telenetted into my system to install the webgui I copied and pasted the first part and then it was installing and telnet crashed. Telnetted back in ran it again, crashed, now system comes up exactly like what ryan's screenshot looks like.

vl1969 is correct, "most" dual proc mobos will run with one cpu but some can't access the second bank of memory, some can. Also, most dual proc mobos have a primary cpu socket, make sure you identify that socket and put your single proc in that socket and not the secondary one. Most will not boot without a processor in the primary socket, but all depends on the mobo. Best place to check these things is the manual but I'm almost positive all Supermicro dual proc mobos will boot with one processor. {edit} Here is the mobo manual http://www.supermicro.com/manuals/motherboard/SR56x0/MNL-H8DCL-%28i%29%286%29%28F%29.pdf and it states on page 29 "For a dual-CPU system, repeat these steps to install another CPU into the CPU#2 socket (and into CPU#2, #3 and #4 sockets for a quad- CPU configuration" so it is socket dependent.

No clue how long this will last. http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=360836409874

BobPhoenix is correct, but only if there is nothing in front of the regular PCI slot that would prevent the rest of the PCI-X card from seating properly since it is longer and the rest of the golden fingers will be exposed, such as capacitors or heatsinks for chipsets, etc. I've used a PCI-X card in a regular PCI slot lots of times and it works fine.

This is PCI-X not PCI-Ex. There is a huge difference. PCI-X is old and usually found on server motherboards. PCI-Ex (express) is the newest and found on most newer boards. Make sure you know which kind your motherboard supports.
