I have tried both SCSI and SATA are OK for cdrom. seems SATA can not always works well. But SCSI can always works well.
CC Adam King: I'm so sorry. I have check again, SATA also can works. The guest can boot from SATA cdrom. Maybe I make a mistake yesterday.
I have set a 14 SATA cdrom on my guest. It can works.
I also check the 440FX data sheet, it can also support SATA controller.
But I have not tried how manySATA controllers that it can support.
Just know one SATA controllers can support 6 SATA devices.

CDROM cannot be extended to more than 4, this is limitation of IDE bus. Change default bus of cdrom to scsi to overcome this limitation.
