Just seen it, thats quite interesting. I'm not that surprised the benchmark performance is in the 286 territory given that a lot will be hampered by the 4.77 Mhz ISA bus. Though I would have expected a bit more, the memory is on the same board as the 386 so that shouldn't be that bottlenecked....

Also interesting to see that win 3.1 wasn't happy running in enhanced mode though a custom intel modified win 3.0 worked.

That may mean there's hope yet of getting things working in win 3.1... Win 3.0 & win3.1 are not that different sometimes you cold get unsupported hardware working in win 3.1 by using a win 3.0 driver.

So I did some searching around the Internet and if this old vfecd.org post is correct, if you've got the intel modified win 3.0 working, you should be able to get win 3.1 working as well with a few tweaks & copied .drv files.

nc_mike's post (post #10) outline's the files & config changes they made. I wonder if this will work for you.
