Trouble with hpcboot.exe on Cassiopeia A-11

So, I tried to run the sh3 hpcboot.exe on my A-11, which is running
WinCE 1.0 (I put it on a PCMCIA flash disk and ran it from there).

It fails -- it doesn't even start up.  I get:

        HPCBOOT is not a valid Windows CE application.

Is it for a later version of WinCE?
