[comp.sys.ibm.pc.misc] Two SCSI devices, one host controller under DOS

larry@palan.uucp (Larry Strickland) (02/17/91)

HELP!  I'm getting ready to upgrade my system with a new disk drive.  At the
same time, I'd like to add a tape backup unit.  Several friends locally have
said that SCSI is _the way to go_ (of course, they all run either UNIX or
an Amiga).

Because of what I do, I _must_ support both UNIX and DOS on this machine.
According to local people, UNIX would be no problem with a SCSI disk and a
SCSI tape both plugged into the same host adaptor.  No one is quite so sure
about what happens under DOS, though.

Will DOS support a SCSI Host adaptor (probably Adaptec as I'm very happy
with my Adaptec RLL controller, but I'd like information on any controller),
a 660 Meg SCSI disk and a tape backup unit (probably an Archive) which is
also SCSI all hooked together?

Is special hardware/software necessary?  Must I get special dispensation?
If so, from whom?

Any help would be greatly appreciated.

larry,

I have the Future Domain TMC 885 SCSI host adaptor.  This card works very
well.  I had no conflicts, even with an XT hard drive controller card plugged
in.  My only complaint is that it takes a few seconds longer to boot.

I personally own a Conner 100Mb SCSI hard drive and a teac tape backup.
While the card recognizes both of these, the hard drive requires no software
to run, but the tape backup does.  In fact, I got my tape drive from a friend
for free without any software.  No one on these news groups seem to have any
software for it, or they are not willing to help me.  Yet, I know that it
works.  Nevertheless, a SCSI adaptor with a hard drive and a tape drive should
be no problem.

good luck and tell us all how it works out

Alan
