Operating System Boot and Shutdown Booting the Red Hat Linux Operating System Red Hat Linux Operating System Booting from the EFI Shell Use this procedure to boot Red Hat Linux from the EFI Shell. See "ACPI Configuration for Red Hat Linux 3 Must Be "single-pci-domain"" on page 189 for required configuration details. Step 1. Access the EFI Shell. From the system console, select the EFI Shell entry from the EFI Boot Manager menu to access the shell. Step 2. Access the EFI System Partition for the Red Hat Linux boot device. Use the map EFI Shell command to list the filesystems (fs0, fs1, and so on) that are known and have been mapped. To select a filesystem to use, enter its mapped name followed by a colon (:). For example, to operate with the boot device that is mapped as fs3, enter fs3: at the EFI Shell prompt. Step 3. Enter ELILO at the EFI Shell command prompt to launch the ELILO.EFI loader. If needed, you can specify the loader's full path by entering \EFI\redhat\elilo at the EFI Shell command prompt. Step 4. Allow the ELILO.EFI loader to proceed with booting the Red Hat Linux kernel. By default, the ELILO.EFI loader boots the kernel image and options specified by the default item in the elilo.conf file. To interact with the ELILO.EFI loader, interrupt the boot process (for example, type a space) at the ELILO boot prompt. To exit the loader use the exit command. 190 Appendix A
