Really isn't it conductive in some way? I've seen that there're those green mask uv solder paint but not really cheap and I will need only two, three centimeters to cover.
By the way, mobo and hard disk bought! The exact one in the photo linked from search engine but I still can't find any specs or manual of it even on the classic website where I usually find easily every jumper configs of these mobo. Few info about it even if it seems it was a usa company with a well specified brand/model of it. But anyway I've seen from an high resolution mainboard image there're not many jumpers anyway but the cache ones.. I suppose it may or not be able to automatically switch to the socket cpu. In an older thread in this forum someone had this mobo but from that thread images it had no cpu soldered so it is not clear how will work if a cpu will be inserted.
I'm not going to risk desoldering the on board 386 even if sure it'd seems to be easier than soldering it of course.
The only photo of the same mainboard on a web page found is here http://redhill.net.au/b/b-93.html looking for "38606".
It's the only page found with a photo of the mainboard and some info. The socket 386 has in the center hole pcb some passive yellow components installed so i'd suppose it's prepared for a cpu to be installed.
And the words on the pcb are MG-38606 Rev: 2.0 MG Technologies USA.
