SPARC: How to Boot a System Interactively

Use this procedure to boot a system and you need to specify an alternate kernel or /etc/system file.

  1. Boot the system interactively. 


    ok boot -a

  2. Answer the system prompts as described in the following table.

    System Prompt 

    Action 

    Enter filename [kernel/[sparcv9]/unix]:

    Provide the name of kernel to use for booting. Or, press Return to use the default kernel. 

    Enter default directory for modules [/platform/`uname -i`/kernel /platform/`uname -m/kernel /kernel /usr/kernel]:

    Provide an alternate path for the modules directory. Or, press Return to use the default kernel modules directory.

    Name of system file [etc/system]:

    Provide the name of an alternate system file and press Return. Type /dev/null if your /etc/system file has been damaged. Or, press Return to use the default etc/system file.

    root filesystem type [ufs]:

    Press Return to use the default root (/) file system. Type UFS for local disk booting, or NFS for network booting.

    Enter physical name of root device

    [physical_device_name]:
