You can obtain more general information about UEFI at the following website:

For an explanation of UEFI settings, see 2.7, “UEFI system settings” on page 36.
Generally, the HX5 UEFI requires little configuration. The factory default UEFI settings allow
the HX5 to work correctly in a 2-socket, 4-socket, and MAX5-attached configuration. There
are, however, a number of UEFI settings that can be adjusted to meet specific needs. You can
adjust the UEFI settings, for example, for better performance.

installed. For example, a database server will generate a separate load on the hardware than
a file and print server.
