I've never seen a passworded CMOS that would allow one to look at the CMOS
information.
There is a much faster way to do this, in most cases.  Many computers have a
4-prong connector, often with the second pin missing, which is used to attach
the external battery that you mention above.  Attaching a jumper to two of
the pins (usually the last two) and waiting for a few minutes, will discharge
the CMOS, wiping it out.  After a few minutes, remove the jumper and turn the
computer on, to see if it did the trick.  On Packard Bell computers, there's
often a separate password jumper connector; just attach a jumper, turn the
computer on, and it should then tell you to turn the computer off and remove
the jumper.  Do this, and turn the computer back on, and the password should
be gone, but not the other CMOS information.
