Disabling Hyper-threading on a Dell PE R720

I need to disable hyper-threading due to licensing issues but, I can't find the setting in the BIOS that would allow me to disable it. Does anyone know where I can find the setting on a Dell PowerEdge R720?

The BIOS option is called “Logical Processors”. See the manual ftp://ftp.dell.com/Manuals/Common/poweredge-r720_Owner's%20Manual_en-us.pdf 

However, I am curious, what licensing issues require the disabling? When Microsoft licensing is done “per processor” – it’s actually per physical processor, not processor core or logical one.

What product do you have licensing issues with? Usually licenses are limited by sockets, not the number of cores or threads...

So I doubt turning off hyper-threading will make any difference, even if it were possible to be disabled in the BIOS, which is very unlikely. Only old P-IV socket 478 PC's sometimes had the possibility to enable hyperthreading.

Oracle requires licensing based on all CPU's present physical and virtual.

From what I've found online, Oracle's licensing is based on cores and processor definition, not hyperthreading. If I were you I'd double check with Oracle.
