[comp.unix.xenix.sco] Xenix Hard Disks

Due to the availability of the X binaries for Xenix, I have been doing
the hard disk shuffle to make room.

First my system:
	a 25mhz 386 with 4 meg RAM and an WD1006V-SR2 RLL
	controller with a Toshiba 104 Meg Hard drive

I just added a ST-125 MFM disk with a WD1002-WX1 MFM secondary
controller.  I have formatted it with DOS and plan on moving my DOS
partition from the Toshiba to the Seagate.  (If I had any guts at all,
I would dump the DOS partition completely, but I just can't quite let
go of DOS completely yet.  I don't actually use it much at all, it's
just psychological. :-)) Now the question, can I get Xenix to boot DOS
from the second HD on the secondary controller?  Otherwise I could
leave the smallest possible DOS partition on the Toshiba just to boot
DOS from and then keep most of the DOS stuff on the Seagate drive.

The next big question: How should I increase my disk space a lot?  I
plan on adding a secondary drive, and probably dumping the ST-125.
Since my WD1006 controller will work with a second drive I'm very
tempted to get another RLL drive.  I need a half hight drive and would
like about 100meg.  Unfortunately, I can only seem to find two options:
a Seagate ST277R 65meg (a bit small) or a Microscience 1090 120Meg.

I would guess the Seagate is good quality; it costs ~$250 and is
probably a safe bet, but is kind of small.

At only $345 The Microscience sounds too good to be true.  I have
never heard of Microscience.  Is there a catch with this drive?  Only
3 places in the Computer Shopper seem to carry it.

There might be a third option.  A salesperson at one hard disk vender
suggested I could add a SCSI drive and controller.  That would seem to
be a good idea, but it I would have to add a SCSI host adapter.  This
is no problem if it doesn't conflict with my RLL controller.  But, the
big question is, will it work with SCO Xenix 2.3.2?  I don't think I
have the GT version which works with SCSI so I think this set up up
might not work with Xenix.  I also want to make sure all this hardware
will work when I someday upgrade to some 386 UNIX.  Any advise here?

I realize I have asked a lot of questions, but I'm a poor grad student
who has scraped and saved in order to get a new hard drive and I can't
afford to make a mistake with this purchase.

Thanks in advance,  (reply with email or to the net)
