  Er, I just read your post again, and you did say that.  However, you asked
us not to quote you, so I won't.  :-)  I understood you were not clear on
the matter, and I was trying to clarify things.

  Sorry, no.  The context of your remark was the "Reset Configuration Data"  
setting.  That setting applies to the ESCD the BIOS maintains, which is not
kept on the cards.  Both PCI and ISA PnP cards get the configuration from
the host computer; they have no say in it themselves.  (Well, that isn't
strictly true; the cards can report their limitations, e.g., that only
certain IRQs, DMAs, or memory ranges will work.  But the host (specifically,
the PnP enumerator) tells them what to actually use.)

  It is certianly possible for a card to keep *other* settings in NVRAM
(e.g., the volume on an internal modem), but that is not what you were
talking about.

  As I said in *my* post:

  So, again, that has nothing to do with the "Reset Configuration Data"  
setting.  :-)

  Interesting.  I have never seen that before.

  That is not necessarilly unrelated.  Sometimes, the "ESCD update" message
will always appear, even when the "Reset Configuration Data" is set to
"Disabled".  I do not know if that is because the BIOS designers just felt
it better to regenerate it every time, or because some piece of hardware is
causing the BIOS to think it needs to, or because the BIOS is buggy, or
what.  :-)
