Did you boot your PC from the DOS 3.1 diskette?  I had difficulty of same kind
going from DOS 3.0 to 3.2 and came to the conclusion that the new BIOS files
took more space than the old 3.0 files did.  I never found a way for SYS C: to
work with these two releases, however, I have done it many times with 2.1 to
3.0 (work in a corporate information center).

I would suggest doing a SYS C: from your 2.1 diskette ... thus putting back the
original IBMBIOS.COM and IBMDOS.COM files (have never erased those prior to
updating DOS) and then try the SYS C: after booting from DOS 3.1 diskette.
