F/up with the pci-e card working.

Thanks for your input. Maybe you can advise if there is a way to
determine what the bios defaults are without resetting to the defaults.
Default conditions for a retail motherboard, are recorded in the
motherboard manual.
HP does not provide a mobo manual. HP's 'name' for the Asus mobo does not
correspond to any Asus listed mobo/s. I've had to guess at the Asus mobo
which is being used by looking at Asus mobo layouts and specs and I
arbitrarily decided that the M2NPV-MX was most like my HP mobo layout, but
the Asus manual for the m2npv-mx does not correspond to the appearances of
my BIOS setup. It is similar, but appears to be of a different
'generation' and doesn't have a primary video option section in the
Advanced tab.
Default conditions are designed, such that
you should be able to get into the BIOS.
You would think so.
I decided to take the bull by the horns and take my chances with the card
working by using the following sequence. Physically install card in its
slot, but leave monitor attached to the integrated video. Bootup and
install drivers for the installed card which is recognized by Win.
Shutdown. Bootup and access setup and change primary video from
integrated to pci-e and save and shutdown.
Move monitor vga connector to the card's vga. Bootup. That was where I
was afraid that if the card were no good that I could not get a screen.
Since the card turned out to be OK, I got the bios POST screen and the
windows screen which only needed to have its configuration resolution
adjusted.
In that sequence I also tested whether or not if the monitor were
connected to the onboard video vga if I would be able to get video after
the bios setup had been changed. It would not. If the card weren't
working I would have needed an alternate strategy, such as clear cmos to
get access to bios video to get into setup again and hope that I could
guess right as to what the default video configuration was.
The biggest danger of "bricking" a motherboard, is flash upgrading the
BIOS. What you're doing, is relatively safe, by comparison.
It is just disconcerting to not know what the bios defaults are and for
the OEM to not provide a mobo manual or for HP and Asus to not 'get
together' and provide a mobo manual corresponding to what HP claims is an
Asus name. Here's what I pasted earlier from HP's webpage on the
SR2027X - "Motherboard manufacturer's name: ASUS A8M2N-LA - HP/Compaq
name: Naos-GL6". Asus has other A8s but not that one, Asus has other
M2Ns but not that one.
When I first started researching the /actual/ mobo's designation instead
of what HP said, I found other discussions of the confusion along with
opinions about which Asus HP was using.
