Default BIOS date and time in a Pentium 4 not adjustable.

A Pentium 4 with Intel system board here.
When powered up the screen displays
GB85010A.86A.0078.P18.0110081719
...
CMOS Battery Low
CMOS Date/Time Not Set

No response to any keys when attempting to adjust date and time. No
problem changing other BIOS parameters. This is only to prevent the
user from adjusting the clock when it can't keep time with power off?
A failure in the BIOS?

Thanks, ... Peter E.

Change the battery. It is possible that the low battery condition is preventing any further action.

The parameters of the BIOS are grooved in a Flash memory

THe date/time comes from a clock circuit ; it needs a higher minimum
voltage for operate

Check the onscreen instructions carefully (normally on the bottom row)
on what keys to press to change item values. Sometimes it's F5/F6,
sometimes something else like direct entry (guess you tried that).

Thanks for the replies.

Replaced the CR2032 cell with one fresh out of the package. No change
in BIOS behaviour. Date and time still not changeable.

Some of those older boards had a potted module with a 0.6" chip form factor.

IIRC: it was a Dallas RTC chip (which may have been more or less compatible
with the original Motorola chipset RTC). That had a couple of lithium coin
cells stuck on top and potted.

As clear possible with this camera and without losing image size.
I recognize only the one lithium cell.

Retrieved the Intel BIOS updater and updated. The latest version
available is the same as the extant version. No problem reported in
the update process.

Booting stops with these being the last three lines on the screen.
CMOS Date/Time Not Set
Press F1 to Run SETUP
Network selected as first boot device for current boot

There is no 8P8C connector on the system board and no Ethernet adapter
installed. Nothing about network in the boot area of the BIOS
configuration. The BIOS identifies the WDC drive with a bootable
system as "WDC WD1200JB-00DUA3" but won't boot from it.

None of the capacitors are bulged. With the capacitors installed, no
leaking electrolyte visible. Replacing capacitors seems a poor
investment for an uncertain return.

Any further thoughts before scrapping the board?

Thanks, ... Peter E.

Hi Peter,

Are there two pins on the motherboard that you can temporarily short that
will clear the CMOS settings?

What OS? - most I've seen have time and date icon on the taskbar, have you
tried setting it there?

Something gross !!

Are you sure that during BIOS setting, your keyboard is Numlock ?

There is a pin set J8C2; described here.
http://www.intel.com/content/www/us/...000005690.html
With the jumper on 2-3, a maintenance menu added in the BIOS
configuration allows passwords to be cleared. No evidence of any
password set but I cleared all. After that put the jumper back to the
normal 1-2 position and booted again.

Still could not adjust the clock but the "Save changes and proceed"
option worked and the system booted. Not sure that clearing the
passwords made a difference. I could have just failed to recognize
how to pass the clock problem earlier.

Debian and antiX. Now that I see how to start the OS, will try to set
the clock there.

Numlock is ok.

Will return to this machine February 13 or later. Appears promising now.
