I've written a little script to get everything from "Pentium (Socket 4/5?)", "Pentium Pro", Socket 7, Slot 1 and Slot A from Biostar. Including BIOS, Manual, Jumper settings and test reports.
I'll post it here when it's done.
EDIT: Here's what I got. https://mega.nz/#!W8hilCqR!GZCya1uZfMoq3tjVdK … avRMTovk1ICLl8c
I got most of this from different Biostar sites on Wayback Machine, all from different periods in the 90s and 00s.
Contains manuals, jumper settings, test results (hardware validation, spec vs actual result, etc), latest BIOS and manuals where possible. Some have multiple jumper settings or multiple manuals from different periods in time. Some are PDFs of the actual manual, some are just HTML pages that I saved as a PDF. I also found some 486 stuff and a single 386 thing on some of their subsidiary sites. I had to get a bunch of it by hand, but it turned out pretty well as a nice little collection.
I haven't verified any of the BIOS files.
I think this is a nice starting point. I'll see what else can be scraped later.
