Sorry if this has already been mentioned, but for Adaptec SCSI
controllers, the bios is not loaded unless there is a bootable
device on the chain, but it (the bios code) isn't needed in order to
use tape drives on the chain, so that isn't the problem here.
Sorry I can't speculate what the problem is, but I have a similar
setup (with 2940) and a DAT but no bootable devices (thus bios code
not loaded) and it works fine. Didn't do anything special either.
