Examples for commands such as boot  and setenv  can be found throughout this FAQ.
 

At the boot prompt (ok) you can type the command boot, followed by the device that you want to boot from. Examples:

   ok boot floppy    Boot from the floppy disk
   ok boot fd(0,0,0) Boot from the floppy disk
   ok boot cdrom     Boot from the CD-ROM
   ok boot sd(0,6,2) Boot from the CD-ROM
   ok boot tape      Boot from the tape device
   ok boot sd(0,4,0) Boot from the tape device
   ok boot disk      Boot from the hard drive
   ok boot disk2     Boot from the hard drive with SCSI ID: 2
   ok boot sd(0,2,0) Boot from the hard drive with SCSI ID: 2
   ok boot sd(0,1,3) Boot from the 4th partition of SCSI ID: 1

Some older proms do not understand some of the "short" device aliases (i.e. cdrom), and you will need to use the longer explicit form.
