I solved the problems I had on the 386DX-40, the first was very simple to solve, missing the Turbo switch I put a jumper on the jumpers, the PC now goes to 40MHz (while before it went to 20) and also the RAM count has sped up.
Unfortunately I was unable to get the 128MB CF from SanDisk (put in place of HD) to work, other CF cards work, currently not having a similar capacity I used an 8MB from Canon, installing DOS 4.01 and if I can also Win1 .03 (free space permitting).
I loaded everything through some 1.44MB floppies, the one of DOS 4.01 I had made as a backup of the PC almost 30 years ago, fortunately it is still readable, unfortunately I cannot find those of DOS 3.3, but I think they were on 5.25 floppies which unfortunately I do not have anymore.
I also loaded a couple of DOS programs and utilities, with the latter I did some bench as you can see from the images, the results I think are normal considering that the PC is not yet configured at best, unfortunately I lost a sheet where I had written the settings optimal for the BIOS (voice by voice), there are not many options, but for example there should be the one that shows the MHz of the CPU when the BIOS starts, and others that maybe can speed up the results of the bench by a few tenths of a point .
