Try other Fkeys IIRC F8 or F2 takes you to boot menu(press it right
after you hear bling).

I did try F2, but apparently lacked the timing. Now I've change
bootsequence to CDROM first, harddisk second. So far, still no boot from
CDROM though.

Not all SCSI cdRom drives are bootable out of the box some require a
specific flash code.
Plextor drives are your best bet.

I would personally suspect AIX Cd you are trying to boot from specially
if it is not genuine....CDrom must contain PREP boot sector you can
check cd with Linux machine by command fdisk -l /dev/sda if PREP is not
there then it wont boot from that CD.

What version of AIX are you trying to boot?
The PREP machine won't boot AIX later than 5.1

Also, what are you using for a console?
If not a graphics console, try the number 5 instead of F5.

The issue has been solved. The cdrom is bootable, but the wrong PowerPC
platform: Apple PPC. Apparently, there's no BSD for the IBM PowerPC.

Your system is PReP architecture. You must take this into account when
loading the system. At minimum, NetBSD and Linux will run. NetBSD
probably has the best support of the two.
