Procedurex86: How to Boot a System to Run Level 3 (Multiuser Level)

Use this procedure to boot a system that is currently at run level 0 to run level 3.

  1. If the system displays the Press any key to reboot prompt, press any key to reboot the system.

    You can also use the Reset button at this prompt. If the system is shut down, turn the system on with the power switch.

    The Current Boot Parameters menu is displayed after a few minutes.

  2. Type b to boot the system to run level 3, then ress Enter.

    If you do not make a selection within five seconds, the system is automatically booted to run level 3.

  3. Verify that the system has booted to run level 3.

    The login prompt is displayed when the boot process has finished successfully.

Example 16–1 x86: Booting a System to Run Level 3 (Multiuser Level)

For new installations, typing b at the boot prompt automatically boots 64-bit capable x86 based systems to 64-bit mode. For upgrades, typing b at the boot prompt also boots 64-bit capable x86 based systems to 64-bit mode, unless the eeprom boot-file parameter was previously set to a value other than kernel/unix.

This example shows how to boot an x86 based system that has 64-bit computing capabilities to run level 3.
