  • To boot in 32-bit mode (if not the default):

    setenv boot-file /kernel/unix
    (or, if that does not work, use /platform/sun4u/kernel/unix )
    boot

  • To boot in 64-bit mode (if not the default):

    setenv boot-file /kernel/sparcv9/unix
    (or, if that does not work, use /platform/sun4u/kernel/sparcv9/unix )
    boot

  • To go back to the default (empty) setting:

    set-default boot-file
    boot
