I've never seen a hard disk controller "soldered" to the standard PC
floppy disk controller; most Maynard products are pretty good.  If
you can't separate the two boards, you could replace them both, and
use the same hard drive.

The very early PC's (which don't have the (B) stamped on the back)
needed a ROM BIOS upgrade to boot from hard disk.  If you're booting,
chances are good that the BIOS is ok.

Check the new floppy disk drive to be sure the option jumpers are
set correctly for your machine.  You might see the behavior you
mentioned if the drive isn't set up properly.  If your original
floppy disk drives can't read another diskette, you can try
formatting on the same drive that you want to read from.  If that
works ok, it does indicate a possible head alignment problem.
