1. Obtain the SmartStart Scripting Toolkit ("Obtaining SSSTK" on page 8). 2. Run the SmartComponent for the most recent version of the SSSTK, note the directory that it is in, and then change to it in Windows® Explorer or a command window. 3. Build a Windows® PE boot image. For more information, see "Preparing the bootable media" in the HP SmartStart Scripting Toolkit Windows Edition User Guide. 4. Boot the image, and from Windows® PE, build an input CONREP.DAT. 5. Run conrep ("Using conrep to reconfigure BIOS" on page 9). Q. Can I interrogate the memory operating speed? A. Requested memory operating speed can be interrogated using RBSU or conrep. The information returned indicates the requested or programmed operating speed. Q. How can the actual memory operating speed be confirmed? A. Memory operating speed can be confirmed using memory benchmarking tests. On HP ProLiant servers utilizing Intel® Xeon® processors, RBSU can configure the memory operating speed. Q. Why don't all the server blades boot when power is first applied to a fully populated enclosure? A. The OA manages power based on the available power supply capacity in the enclosure and the power requested by each device that is installed in a bay. Before a server blade is installed for the first time, it is programmed to request the maximum possible amount of power that it is capable of using when fully configured with all possible options. During this first boot, the OA requests a stress test on the server blade and monitors the actual peak power used. This value is then retained for subsequent startups. If all server blades in the enclosure request maximum power simultaneously, the OA may determine that the capacity of the power supplies could be exceeded and may deny power to one or more server blades, even though the power available is adequate to power all of the server blades under normal load. Sequentially powering on new server blades may address the issue. OA power management is a complex subject and well beyond the scope of this document. The preceding discussion is greatly simplified. For more information about the Onboard Administrator and HP ProLiant BladeSystem enclosures, see the HP website (http://www.hp.com/go/bladesystem). Q. Does setting the server blades to highest performance state affect the ability of all server blades in an enclosure to boot? A. No, because the server blades always start in maximum performance state. The pre-set power request on first boot is based on the maximum performance state with all options installed.

A. Memory operating speed can be confirmed using memory benchmarking tests. On HP ProLiant servers
utilizing Intel® Xeon® processors, RBSU can configure the memory operating speed.
