There is a new release of the BIOS, A06, available here:
If for some reason you do not see the option to enable/disable hyperthreading in the new A06 release, search the directories of your DSA 7.1 CD for this file: PE4600-BIOSA04.EXE. That version, only found on the DSA, definitely gives you the option to disable/enable hyperthreading.
The PowerEdge 2550 and PowerEdge 6450 do not have Intel Pentium IV XEON processors, so Hyper-Threading does not apply.
The PowerEdge 2650 and the PowerEdge 6650 do use the XEON processors and do have a switch in the System BIOS to disable Logical Processors (Hyper-Threading)
Some Operating Systems and Software do not work with Hyper-Threading (or have special licensing issues), hence the option of disabling.
how about on the 8250? any harm in disabling hyperthreading? how could i turn it back on? detailed instructions would be helpful as i've never done anything with bios before.
[i'm trying to get pinnacle system's "instant copy" to work on my system and they suggested disabling hyperthreading - this is the only reason i'm trying this]
I hope you can help me make sense of the restore power situation. I have a Dell Pweredge 2600 connected to an APC smart-ups 1000 which we purchased through Dell.
I am understanding that during a power outage, the UPS has been configured to shutdown the server quickly instead of trying to wait to see if the power resumes.
The bios settings are set to "resume state" as soon as power is restored to the system.
When the power goes out in the building my ups kicks up and shuts off the poweredge server. The UPS system still has power in it. The server never comes back on though?? I have to go onsite and manually turn the server on. The server is supposed to resume state when power is restored but power actually never goes away, this configuration is just shutting down the server.
Is it possible to disable the hyperthreading on the R200 line of servers? One of our people called Dell support yesterday about it and was told it was not possible. I am not sure whether they checked the Bios or not, but I believe they did. This server was purchased specifically for one program having do to with our phone system and that software will not install because it sees it as having multiple processors. If there is a bios update, can someone please direct me (I'm new here)
I wish I could say that the option were there, but unfortunately it is not. There is an option for virtualization which is disabled, but the option for logical processor is missing completely. Bios version 1.0.0.

Hi John,
We do not have a PowerEdge Server with the name 8250, is this a typo? We do have an PowerEdge 8450, but it does not support Hyper-Threading.
If this is a desktop or laptop system please post your request in the approriate forum. I do not have any experiance with those products.
Thanks for using the Dell Community Forums!

Hello,
I hope you can help me make sense of the restore power situation. I have a Dell Pweredge 2600 connected to an APC smart-ups 1000 which we purchased through Dell.
I am understanding that during a power outage, the UPS has been configured to shutdown the server quickly instead of trying to wait to see if the power resumes.
The bios settings are set to "resume state" as soon as power is restored to the system.
When the power goes out in the building my ups kicks up and shuts off the poweredge server. The UPS system still has power in it. The server never comes back on though?? I have to go onsite and manually turn the server on. The server is supposed to resume state when power is restored but power actually never goes away, this configuration is just shutting down the server.
What am I doing wrong?
Thanks for your help.
