9.8 Changing OS Settings
This section explains the procedure for changing OS settings.
When you have changed to enable Hyper-Threading using the BIOS setting after
starting operation in a one CPU configuration or when you add a CPU, change the
OS to the multi-processor kernel.
When you will reduce the number of CPUs from two to one or disable Hyper-
Threading, change the OS to the uni-processor kernel.
It is recommended that users of the Linux type or Linux array type refer to the Linux manual supplied
with the server.
Customers using the Linux distribution OS on a diskless type server are advised to refer to the Fujitsu
PRIMERGY website (http://primergy.fujitsu.com).
Hyper-Threading is enabled at the time of purchase. For functions and settings of Hyper-Threading,
refer to "8.2.8 Advanced System Configuration Submenu" (pg.219).
Back up the data before changing settings.
Several files must be copied when you change the OS to the multi-processor kernel.
Use the same files as those in the service pack currently applied.
9.8.1 For Windows Server 2003
After adding a CPU or changing the Hyper-Threading setting, starting up the OS changes OS settings. A
pop-up message appears. Follow the window instructions.
