PowerEdge SC1420 3GHz Xeon - EM64T and VT

Hello,
 
I have a PowerEdge SC1420 running MS Windows Vista x64 Ultimate and VMware Workstation v5.5.3.
 
When I attempt to create a new 64-bit Virtual Machine, I receive an error message '64-bit guest operating systems are not supported by this host and will not run.'  When I run the Processor Check for 64-Bit Compatability, downloaded from the VMware site, I receive a message 'This host is NOT capable of running a 64-bit guest operating system under this VMware product.  For more detailed information, see http://www.vmware.com/info?id=152.'  This URL states 'Intel CPUs require EM64T and VT support in the chip and in the BIOS.'
 
I understand that the 3GHz Intel Xeon processor fitted to the SC1420 is EM64T, which suggests that the BIOS may need upgrading to support VT.
 
Can anyone confirm that the 3GHz Intel Xeon processor fitted to the PowerEdge SC1420 is EM64T, please?
 
If so, can anyone provide information about where I can obtain a BIOS upgrade to provide VT support, please?
 
Many thanks
Joe.

In short, EMT64 doesn't imply VT.  One doesn't imply the other, although I don't think you can get a VT chip w/o EMT64 anymore or ever.
 
VT is Virtual Tech. and it hardware support for supporting a Hypervisor.  You have to make sure you CPU support VT before the BIOS will allow you to enable/disable the feature.  Yes, a BIOS VT awareness is also req.

Processor info you'll get this from your BIOS. Many models from Dell from yours particularly can be fitted in variations of Intel processors. You can't just go by model numbers.
 
As of 03-29-2007 - VMware still does support fully on Vista. You can check the VMware support as to when will be available for Vista. As an alternative see Microsoft Virtual PC 2007 and it's free.

Hello,
 
Thanks to DualCpuUser and aytoy for their responses.
 
As suggested by DualCpuUser; I went to http://processorfinder.intel.com/ and I downloaded the bootable version of the Intel Processor Processor Identification utility.  It provided the following information:
Speed 3.00GHz
System Bus 800MHz
Processor 0   
Family F
Modification 4
Stepping 3
Revision 5

Hello,
 
Thanks to DualCpuUser and aytoy for their responses.
 
As suggested by DualCpuUser; I went to http://processorfinder.intel.com/ and I downloaded the bootable version of the Intel Processor Processor Identification utility.  It provided the following information:
Speed 3.00GHz                      Packaging 64 pin uPGA
System Bus 800MHz              L3 Cache None
Processor 0                            L2 Cache 2MB
Family F                                  L1 Data Cache 16kB
Modification 4                          L1 Trace Cache 12 k ups
Stepping 3
Revision 5
 
MMX; Streaming SIMD Ext.; Ext 2; Ext3; and Exec Disable Bit - All Yes
Enhanced SpeedStep; Ext Mem 64; Virtual Technology; and Enhanced Halt - All No
 
Searching the Intel site for 0F43 provided one processor only - sSpec SL7ZB but this was rated at 3.8 GHz and had no details about Supported Features.
 
Going back to http://processorfinder.intel.com/ and selecting to Browse By Processor Family - Intel Xeon Processor gave many 'hits'.  Filtering on 3 GHz CPU Speed; 2 MB Cache Size; 604 pin Package Type; and 800 MHz Bus Speed reduced the number of 'hits' to four - none of which were sSpec SL7ZB.  Two had a CPUID String of 0F43 - sSpec SL7ZF and SL8ZQ but, again, neither gave any details about Supported Features.
 
As suggested by aytoy; I went into the BIOS and looked at the Processor Info:
Processor Type              = Intel(R) Type Xeon(TM) 3.00 GHz
Processor Clock Speed = 3.0 GHz
Processor Bus Speed    = 800 MHz
Processor L2 Cache      = 2 MB
Processor ID                  = 0F43
Hyperthreading Capable = Yes
64-bit Technology           = Yes (Intel EM64T)
 
My conclusion is that the processor does support EM64T but does not support Virtual Technology.  However, this conclusion arises simply from the fact that VMware Workstation gives the message 'This host is NOT capable of running a 64-bit guest under this VMware product.' and that http://www.vmware.com/info?id=152 states 'Intel CPUs require EM64T and VT support in the chip and in the BIOS.'
 
Can anyone suggest any way that I can determine the sSpec of the installed Xeon Processor and, armed with that, a way to establish its Supported Features if Intel's own site ( http://processorfinder.intel.com/) does not provide the details?
 
Many thanks
Joe.
 
PS: Apologies for the incomplete posting before this one.
