Unfortunately I do not have any old, or new cards lying around, and I have
never heard of a way to blindly do a setup without booting an OS first.
Probably just me though.
I guess I'll have to try Samsung and see what they say.
To reiterate though. In my very first post I stated that I had bought a new
24" widescreen monitor and what prompted this thread was that I could not get
it to Post no matted how many times I turned it on and off. Sent it off to be
fixed, checked out OK, sent back to me. Same problem. That is why I brought
up the problem with the old monitor. I lived with that for years. Just knew I
had to push the "button" twice. Annoying but bearable. Thought that these two
conditions must be related somehow. Keep thinking for me guys.
Now I gotta go get a lesson from Paul.
