Sorry, no help here, but I did see the same message under very different
circumstances.  Maybe that will provide a clue.

I was trying to bring up Windows 286 v2.10 on an IBM PS/2-50z running DOS
4.0 with a Logitech Series 2 mouse.  When I tried to install the mouse as
a PS/2 mouse -- as recommended by both IBM and Logitech -- the
installation failed with the same message.  After a few more tries, and
some fiddling around, the message changed to something about "Invalid File
Access Table" and the installation quit without halting the system.  The
FAT appears to be undamaged and all other applications run normally. (BTW,
installing the mouse as a Logitech mouse allowed the installation to
complete and I could bring up Windows, but it ignored the mouse.  It was
probably looking at the serial port, while the PS/2 has a dedicated mouse
port).

After a morning of phone calls to IBM, Logitech and Microsoft it turned
out the version of Windows 286 I have is incompatible with DOS 4.0.
Microsoft is sending out an updated set of disks.  Now I'm wondering what
will happen if/when I upgrade to DOS 4.01. )-:
