I have a sco box with an installed scsi adaptec card that is connected to the hard drive. I tried to install an external tape drive and connect ot to the outside connector on the scsi card. When I try to boot up after connecting the system give a message "Can't find boot device". I do see that the hard drive is recognized at boot time but for some reason it doesn't find it when it needds to boot SCO. After disconnecting the external cable from the scsi card it boots fine again. Any ideas? All help would be appreciated.
