I have a mksysb image on tape that I'm trying to restore to an IBM 7026/F50 running AIX 4.3.3. As an interim step, I'm trying to boot from the CDROM. After starting SMS and selecting the Multiboot option, I'm trying to figure out how to boot from the CDROM (/dev/cd0) where I have 4.3.3 install media mounted. I managed to add /dev/cd0 as the third device in the list of boot devices, but I can't figure out how to boot from it. Do I really need to boot from the CD, or can I install the mksysb tape image directly from SMS?
