On my Asus board, the battery MUST be removed (as the manual states)
in order to clear it. If I only move the jumper, not all settings are
reset. I found this out for a fact less than 2 weeks ago when a BIOS
flash went bad.

Mine's the M2NPV-VM and it clearly states on page 1-20, step 2 to
"Remove the onboard battery." If you'd like to see for yourself, go

I don't doubt that it does. Looks like Asus can't make up their minds.

My guess is that on the newer boards, the jumper bypasses the battery
completely (or more so than on the older boards) making it unnecessary to
pull the battery. Engineering, you know- "If it ain't broke, redesign it!"
I was looking at the board you have as an upgrade, but it only has one
EIDE channel, and unfortunately, I still have 3 EIDE devices that I'm not
ready to part with. I really don't NEED to upgrade (my AMD 64x2 Dual 4800+
is plenty fast), but every once in a while I get that need for speed. Not
having a larger income kinda curbs that feeling, but it's still there :-)

Gentlemen:
I've worked with a considerable number of makes/models of motherboards over
the years and I really can't recall a single instance where it was necessary
to remove the CMOS battery in order to reset the CMOS-BIOS settings to their
factory defaults when the motherboard was equipped with a CMOS jumper. In
every case that I've experienced it was only necessary to short the jumper
to reset the CMOS-BIOS values.
As I'm sure you both know, many motherboards (particularly early types) were
not equipped with a CMOS jumper so obviously the only way to carry out the
preceding was to remove the CMOS battery for some seconds and then replace
it.
I understand SC Tom's reference to that ASUS MB instruction indicating the
need for also removing the CMOS battery in addition to shorting the CMOS
jumper. All I can tell you is that it isn't the first time (and I'm
confident it won't be the last time!) that a motherboard's User Manual (let
alone technical advice from the manuf. itself!) provided misleading or
outright incorrect info re their products & their use. Although I have to
quickly add that our advice to users is virtually *always* follow the
instruction(s) in the motherboard's User Manual/Guide.
Anyway, having said all this and notwithstanding my own experience re this
CMOS battery issue, I learned a long time ago that when it comes to PCs,
*anything* is possible.
So SC Tom...assuming you haven't already done so, have you tested to
determine whether simply shorting the CMOS jumper without removing the CMOS
battery will reset the time/date info & BIOS configurations?
Incidentally, re your refererence to the fact that your motherboard has only
a single IDE channel...
Are you aware that some of the newer (usually the higher-end ones)
motherboards are now coming through without *any* IDE channels? And more &
more motherboards - are equipped with only a single IDE channel. As the
youngsters say, "SATA rules".
