Cepheus (39.42) 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 with:
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.
