43MAXDATA PLATINUM 90002R Server System
Power-on Sequence and Power-on Self-Test (POST)
Turning on the system causes POST to run and control to pass to the boot manager. From the boot
manager, you can choose to invoke the Extensible Firmware Interface (EFI) Shell or you can choose
to go to the Boot Maintenance menu.
The system follows the steps below when you press the power button on the front control panel to
power up the server:
1. The server fans start.
2. POST begins running. POST is stored in ash memory. It checks the drive carriers, processors,
memory, keyboard, and most installed peripheral devices. During the memory test, POST
displays the amount of memory it is able to access and test. The length of time needed to test
the memory depends on the amount of memory installed.
3. Video appears on the monitor that is attached to the server and begins to display boot
progress. The AMI BIOS banner displays the loaded versions of the BIOS, PAL, SAL, and EFI.
4. POST concludes and passes control to the boot manager.
5. From the boot manager, you can use arrow keys to highlight the option that invokes the EFI
shell operating system if it is installed, or you can highlight and select the Boot Maintenance
menu. Selecting the Boot Maintenance menu lets you congure boot options and other boot
environment variables. Booting to the EFI shell causes the following prompt to appear: Shell>
6. When you see this prompt, you can load and start an operating system.
Extensible Firmware Interface Boot Manager
The EFI boot manager allows you to control the servers booting environment. Depending on how
you have congured the boot options, after the server is powered up the boot manager presents you
with different ways to bring up the system. For example, you can boot to one of the following:
EFI Shell: An interactive environment that allows EFI device drivers to be loaded, EFI applications to be
launched, and operating systems to be booted. The EFI shell provides a set of basic commands used
to manage les and the system environment variables. For more information on the EFI Shell, see
The Extensible Firmware Interface (EFI) Shell.
Boot Options: Files that you include as boot options. You add and delete boot options by using the
Boot Maintenance menu. Each boot option species an EFI executable with possible options. For
information on the Boot Maintenance menu options, see Table 4.
Boot Maintenance Menu: A menu of items allowing you congure boot options and other boot
environment variables. Table 4 describes each menu item in the Boot Maintenance menu.
