   I have a few questions for those PC hardware people "in the know":

  1). I am trying to hook up 2 half-height floppies to my IBM-PC.
      One of them is a Teac the other a CDC.  The drives are 
      connected to the proper ribbon cable to a Maynard controller card.
      The system boots fine and diagnostics say I have 2 drives. BUT..
      when I try to format a disk using version 3.00 format, just
      before I get the "formatting complete" message BINGO I get
      a PARITY CHECK 1 message.  Yes I have removed the terminating
      resistor from drive 2 (the CDC).  Question, what does the DS0, DS1
      jumper do?  Do I have to change these and what do I have to change them
      to?

  2). I have a SIGMA 400 graphics board installed.  NOTE: it
      has an on-board ROM which gets initialized upon boot-up.  The
      problem here is that if I don't have the DOS disk in, the system
      should initialize to ROM BASIC but instead I get PARITY CHECK 1.
      I also have an AST board with an additional 384K on it.  Is there
      some contention problems between ROMs?

  3). Just how flukey is DOS 3.0?

Thanx in advance,
-mike-
