Oh, I see. Yes, there have been discussions about problems with the iLO
stuff and the USB "stuff" on FreeBSD.
acd0 = ATA-based ATAPI, e.g. a CD drive connected to an ATA port
cd0 = SCSI-based CD via CAM, e.g. a CD drive connected to a SCSI port
USB on FreeBSD makes use of CAM, not ATA, which means a USB-based CD
should be showing up as cd0 not acd0.
If there is a physical CD-ROM drive which is upsetting sysinstall, I
wouldn't be surprised (sysinstall is depressing, please don't get me
started on it. :-) ). I'm willing to bet it makes the assumption
there's only one CD device in the system.
My recommendation? At the loader prompt, try disabling the ATA port
that acd0 is associated with. E.g. if acd0 is tied to ata1-slave,
then at loader do:
If the system in question has an IDE/ATA disk as ataX-master and the
CD-ROM drive as ataX-slave, then your best choice would be to disable
the Slave portion in your system BIOS and see if that improves things.
(I do not know if you can do something like hint.acd.0.disabled="1";
so I'm assuming you can't). I know you can change the BIOS settings
remotely via iLO.
Hope this gives you some ideas or things to try.
