I remember that someone has an interupt list -- Ralph Brown -- is that how you
know how to interpret these values?  with an interupt list?

I went to his site, but there it says:
<<
0E INT 0E C - IRQ6 - DISKETTE CONTROLLER
0E INT 0E C - CPU-generated (80386+ native mode) - PAGE FAULT
0E INT 0E C - HP 95LX - EXTERNAL CARD INTERRUPT
>>

How do you know which one is relevant?

After looking around a bit, I found ...
http://www.abwillms.demon.co.uk/prog/
...where it mentioned a tutorial:
<<
Libints

Old DJGPP protected mode hardware interrupt handling library. Includes a
tutorial on hardware interrupts in general, and a
neat memory locking system. Superceded by:
>>

I am thinking that this stuff help me to understand, for example, the things
that Windows says in the "details" section of the dialog box for a program
error, and also the text that follows a program crash.  That's what I think you
mean, anyway.
