Uefi Shell And Hp Posse Commands - HP Integrity rx2800 i4 User Manual

The UEFI boot manager loads UEFI applications (including the OS first stage loader) and UEFI
drivers from an UEFI-defined file system or image loading service. NVRAM variables point to the
file to be loaded. These variables contain application-specific data that is passed directly to the
UEFI application. UEFI variables provides system firmware a boot menu that points to all the
operating systems, even multiple versions of the same operating systems.
The UEFI boot manager enables you to control the server booting environment. Depending on how
you have configured the boot options, after the server is powered up the boot manager presents
you with different ways to bring up the server. For example, you can boot to the UEFI shell, to an
operating system located on the network or residing on media in the server, or the Boot Maintenance
Manager. For more information, see
