I have an old PC-XT clone with a 15 megabyte hard disk (RLL controller).
I just got an EGA monitor and video card which I tried to install.
I know very little about hardware, but I was told I needed to replace the
ROM BIOS because the original would not recognize EGA.  I had the chip and
replaced it.  Now, my PC does not recognize the hard disk at all.  It thinks
it has four floppy disks (A-D) as per the floppy disk controller, but doesn't
see the hard disk controller.

Any suggestions as to what to try next?  I tried putting everything back the
way it was...and the PC still doesn't recognize the hard disk.  One person
suggested that I *MUST* reinitialize the hard disk and reformat it.  That
seems a bit drastic to me.  I mean, the information should still be on the
hard disk and should be usable.

I would *REALLY* appreciate some help if anyone out there has some
suggestions.
