These manuals are no longer available at the websites of the manufacturers. Some may still be around on other places on the web.
I realize it isn't complete, I'll try and put as much as possible online here. One of the best options to find a manual for an old 486/586 motherboard is the
WebHQ motherboard manual page
which used to reside on (now gone, Steve has given me the files to host here)

If you cannot find it below or on WebHQ, there's a good chance it is in the MOBOKIVE copy here since Toby B. has had some server problems.
It seems the original is no longer recoverable making this the last surviving copy. The mobokive was originally setup by Hardware Junkie (Nic D.)

At one time a person named Kuriaki had loads of files online, I was never able to collect the whole set, the parts I did manage to download can be found in The KURIAKI Archives index

Update nov 6 2020: Currently working on a new project that will make use of the archives. Stay tuned!
