Disabling 2nd processor on PE2650 through BIOS

Hi,

The only way to disable the 2nd processor on the PowerEdge 2650 is to physically remove it from the system.

Mark,

I tried that (removing the 2nd processor) and the server wouldn't even reach the BIOS, the front display writes "Missing CPU 2".  Any other ways we can test this ???

Thanks in advance

If you are running Windows NT, 2000 or 2003 then you can put an entry into your BOOT.INI file to instruct Windows to use only 1 CPU.

You would add the    /ONECPU   switch to the end of the line in C:\BOOT.INI that contains the entry to start Windows (under the [operating systems] section) to tell Windows to only use 1 CPU.

You can also use the    /NUMPROC=x    (where x is the number of processors to use - in this case, 1) option instead of /ONECPU if you wish.

See http://www.sysinternals.com/ntw2k/info/bootini.shtml for more information on these and other switches.

Hi SiD,

The PowerEdge 2650 does not require a terminator card like older systems did. The only reason I can think of for this message is the Voltage Regulator Module (VRM). Did you also remove the 2nd processor VRM when you removed the 2nd processor?

Mark, Phil,

Thanks to both of you! 

The VRM needed to be removed as well, it booted fine without it.  As for Phil's suggestion, I will try that when I get another Maintenance window :-)

Thanks again for the help
