2-34 General DescriptionFlow of POSTThis section walks you through how POST is performed.1. When you power on the system, one selected CPU/PCI module will start up.POST will be performed on this selected CPU/PCI module.2. Memory check starts.A message appears at the upper left of the screen to show that the basic and expandedmemories are being counted. The memory check may take a few minutes to completedepending on the server’s memory size. Likewise, it may take about one minute for thescreen to appear when the server is rebooted.Note that if you have replaced the PCI module, the server will perform a reset of the MACaddress, then reboot itself before the memory check.3. The server starts processor check, IO check, and initialization.Several messages appear: they show the ID of the selected CPU/PCI modules, informationon the processor, detection of the keyboard and mouse, etc.4. A message appears at the lower left of the screen, prompting for startup of the BIOS setuputility “SETUP.”Press to enter SETUPYou will need to start it when you want to modify the configuration for using the server.Unless this message appears together with an error message, you do not need to start theutility to modify the configuration. (If you wait for a few seconds, POST will go onautomatically.)To start the SETUP utility, press F2 while the above message is displayed. For setting andparameter functions, see the section of BIOS setup.When SETUP is completed, the server will reboot itself automatically and perform POST.5. A message appears prompting for startup of SCSI BIOS setup utility.When a built-in SCSI controller is detected, a message will appear prompting for startupof SCSI BIOS setup utility. (If you wait for a few seconds, POST will go onautomatically.)If you press Ctrl + N, the SCSI BIOS setup utility will start. For setting and parameterfunctions, see “SCSI BIOS (SCSISelect)” (page 4-30).You will need to use this utility, for example, when you have changed the server’s internalSCSI device connections. However, you usually do not need to use it.When SETUP is complete, the server will reboot automatically and perform POST again.If multiple SCSI controller boards are mounted on the PCI bus, the SCSI BIOS startupmessage will appear for these boards in numerical order (PCI #1, PCI #2, PCI #3…).6. The screen shows SCSI ID numbers used by the connected SCSI devices.
