Kevin,
Try these. The following link is to part of the 386 docs, which appear to
be wrong, as is the mail that Willow originally sent,
http://webster.cs.ucr.edu/Page_asm/Doc386/LAR.HTM.
The following errata, correct what is wrong in this document, basically the
trap and interrups are flip-flopped. See point 5 of the following:
http://developer.intel.com/design/intarch/techinfo/pentium/specupdt/doc_ch.h
tm.
If you need more info, let me know. I will send it when I have a little
more time available to write.

Willow,
I haven't heard back from you on this. You claim the docs support
your mods below. Which docs are you using? Please send the
title and page number. I don't see anything that supports your
comments.
