xSeries 455 Planning and Installation Guide
4.1 Using The Extensible Firmware Interface
Intel has introduced the Extensible Firmware Interface (EFI) as a means of giving
greater control to the operating system and to the end user as to how the system
starts and works. In this chapter we familiarize you with this environment.
The concept of the EFI is described in “Extensible Firmware Interface” on
page 29.
Table 4-1 shows the common tasks you would perform in either BIOS or via a
DOS diskette and how they are now performed on the x455.
