A Sun SPARCR system prompts for a boot command unless the
autoboot flag has been set in the nonvolatile storage area used by the firmware. Machines with older PROMs have different prompts than that for the newer V2 and V3 versions. These newer versions of PROM are also known as OpenBoot PROMs (OBP). The
boot command syntax for the newer types of PROMs is:
boot [OBP names
The OBP names specify the OpenBoot PROM designations. For example, on Desktop SPARC systems, the designation
sbus/esp@0,800000/sd@3,0:a indicates a SCSI disk (
sd) at target 3, lun 0 on the SCSI bus, with the
esp host bus adapter plugged into slot 0.
You can use Veritas Volume Manager boot disk alias names instead of OBP names. Example aliases are
vx-disk01. To list the available boot devices, use the
devalias command at the OpenBoot prompt.
The filename argument is the name of a file that contains the kernel. The default is
/kernel/unix in the
root partition. If necessary, you can specify another program (such as
/stand/diag) by specifying the
-a flag. (Some versions of the firmware allow the default filename to be saved in the nonvolatile storage area of the system.)
See "Restoring a copy of the system configuration file" on page 45.
Boot flags are not interpreted by the
boot program. The
boot program passes all boot-flags to the file identified by filename.
