Thanks for info.
I have a scanner plugged on the scsi port. But i don't switch on. I'll
try with the scanner unplugged.
Have U got the message SCSI RESETING? How long did it take to scan SCSI Bus?
Cheers.

If your CD-ROM driver is connected at ID 3, you have to type
"boot scsi-int/sd@3:0" to boot. The first "3" means SCSI ID and
the following "0" means the default partition.
On my Apus2000 (with OF2.0), 1.5.2 ISO CD-ROM works:

So I guess you have to check termination power setting
