Sorry it took me so long to get back but work is taking up most of my 
free time as of late.  In any event, I applied the patch to a clean 
test9, enabled the PNP support and the PNPBios sub option.  I did not 
check the sub option, the creation of the /proc interface.   It still 
crashes by the way.  Here's the output.

I don't know if you need all of that again but I figured it couldn't 
hurt.  Some of the stuff looks different from before.  As far as the 
dmi_dump goes, I'm not certain what you want or how to get that.  The 
best I could find out that sounds reasonable is the dmidecode app.  I've 
attached the output of that command.  If this is not what you wanted 
please let me know how to get what you want and I'll strive to get it to 
you.

Thanks for looking into this,

Gary
