Cepheus (41.37) is a SPARCStation. At boot time SPARCstation's are
under the control of the Sun OpenBoot. Obtain the OpenBoot prompt with
the keyboard L1 (which might be labelled Stop)and A simultaneously.
The prompt is a simple “ok”. Note that the prompt can even
be obtained from within SILO (the Linux Loader for Sparc) or using the
halt command in SILO. Then boot the machine from CD-ROM
ok boot cdrom
At the boot prompt choose s (SCSI) and the system then boots from the CD-ROM. To boot single user simply use boot -s.
