Picture of Inboard 386/PC:

I have a german and a englisch version of normal Windows 3.0 and a version of Windows 3.0 mme. But there all don`t run in enhanced mode. In fact there are this different versions.
Windows 3.0
Windows 3.00a
Windows 3.00a mme with Multimedia EXtensions 1.0, and
Windows 3.0(0a) for Intel Inboard 386/PC
You can take a look on
http://www.winhistory.de/index_ENG.html to see the different versions.
Windows 3.1 shoudn`t work too,like it says in this excerpt:
WINDOWS 3.1 FOR THE INBOARD 386/PC
Even though the Inboard has been discontinued, Intel will continue to
provide technical support to Inboard 386/PC owners and will honor the
five year warranty. However, we will not be releasing a version of
Windows 3.1 for the Inboard 386/PC.
Releasing special versions of Windows is something extra Intel has done
for its customers. The decision to stop was not made lightly, and we
have reconsidered it several times. Each time we did so, we came to
the same conclusion: It would be best not to release a special version
of Windows 3.1 for the Inboard 386/PC. There are several reasons for
this decision:
* The Inboard 386/PC has been on the market for many years. It was
designed to give 8-bit machines (such as the IBM PC/XT) the
benefits of a 386 CPU. For a long time, 386 specific software ran
wonderfully on Inboard 386/PC equipped systems. While Windows 3.0
and 3.1 make use of 386 CPUs, they also rely on advanced hardware
that the Inboard 386/PC cannot provide to the XT motherboard: two
programmable interrupt controllers, a 16-bit DMA controller, CMOS
memory, and a 16-bit bus.
* Intel invested a lot of money, time, and effort to modify the
Windows 3.0 Virtual Device Drivers (VDDs) to support the 8-bit
architecture of an IBM XT. Windows 3.1 would require this
investment be made again. It's possible that we would have to
modify every subsequent release of Windows, and there is no
guarantee that Windows' use of advanced hardware can continue to be
supported on Inboard 386/PC equipped systems by modifying the
Virtual Device Drivers.
* Other software packages have modified VDDs too. Any software
package that substituted its own modified VDD for one of Intel's
modified VDDs would be incompatible with the Inboard 386/PC release
of Windows 3.x.
* Microsoft has stated publicly that they are moving away from
supporting 8-bit system architecture in their software products
(eg. Windows 3.1 has dropped the REAL MODE function that Windows
3.0 had). Microsoft could have designed their software to allow
for 386 based machines with an 8-bit system architecture. They
chose not to. Their position is understandable: they want to take
advantage of the performance benefits offered by advanced hardware.
There is a trade-off, however. With this software design trend,
older system architectures become obsolete.
With the decrease in prices for i386cpu motherboards, and the increase
in software which use the advanced hardware on i386 CPU based systems,
the Inboard 386/PC is no longer a viable solution. The Inboard 386/PC
was marketed as a way to extend the life of a PC or XT system. It did
that very well for many years. But, there are limits to what it can
do, and Windows makes it clear that those limits have been reached.
