I recently ordered a 160 Mb Micropolis ESDI hard drive for my Zenith 386.
This was to be installed in addition to the 72 Mb MFM drive already there.
Now I've been informed that an ESDI drive and an MFM drive will not operate
in the same computer and that I should return the ESDI for a SCSI which
will coexist with the MFM.  Then someone else told me that it's true that
both controller cards can't be in the same machine but that I can run both
drives off the ESDI controller card.  Now I'm confused.  Can anyone
help me out????

One other problem but easily overcome, I think.  The Zenith's setup ROM
has a menu for choosing drive letter and entering the type of drive installed.
There are no choices for any drive over 116 Mb in size.  I guess Zenith 
didn't think anyone would manufacture or want any such thing.  I assume 
that can be overcome by using a third party setup program?

Please e-mail responses.

Thanks!!!
