WANTED: Intel Architecture Labs 1990’s CD-ROM’s. They appear to have maybe been monthly. They contained a mirror of Intel’s ‘download.intel.com’ ftp server, specifically the /ial/ subdirectory which is not in the 2014 backup of the site on archive.org.

Lots and lots of white papers and design guideline documents in there. Especially looking for ones from the late 1990’s (1998-ish onward) if they exist. I’ve seen references in mailing lists to them that lead me to believe they do.
Example gem: intel trying to cover its ass after the FDIV bug, and have some more FDIV
