If you're talking about booting to an SCSI drive, you have to have

There are no IDE devices at all, so that's not the problem. It boots
from the SCSI HD regardless of the SCSI adapter bios setting to
"boot from CD-ROM."

If there is an utility for the SCSI host utility, run it and set it to boot from
the SCSI ID that is for the Yamaha drive. The otherwise alternative would
be to assign the CDROM a target ID of 0 and the HD an unused ID that
is greater than 0, i.e., swap their ID numbers.
