Otherwise, it proceeds, and both of the actual cdroms (0 and 2) may be succesfully mounted. Note, the cdrom with scsi-id2 is actually "NEC CD-ROM DRIVE:501", and is recognized as such, if it is porbed first. >How-To-Repeat: Put two cdroms on the aic-7850 cable. (I do not have any scsi disks). Result will depend on their SCSI ids and, possibly, brands. >Fix: Find the working combination and wait for the FreeBSD guys to fix it. >Audit-Trail: >Unformatted:
