i had a CMOS checksum error on my CNC mill. So, I installed a new

Remove the new battery & short out the socket for a few seconds, then
reinstall the battery. You may have some corrupt data in the CMOS
scratchpad RAM.

Try another power supply, if you have one. You may have a dying or
dead motherboard. Unplug all the drives, and cards except the video
card, if it isn't part of the motherboard. If you can't get the bios
screen to flash, look at the electrolytics on the motherboard, and the
ones near the processor in particular.

If they are bulging, they need replaced, or replace the motherboard.
They are a special low ESR 105° C type capacitor, and not always easy to
replace, because they are soldered to internal layers. If you can find
the exact same type motherboard, and move the processor to the
replacement board you shouldn't have to reinstall any software.

This is a P4 motherboard with an ISA slot for my Galil card. Rare and
expensive to replace. I happen to be in Ocala Tuesday. Are you
interested in looking at it?


I just learned that a severly disabled freind of mine died last night
& I'm just not up to it tonight. I only slept a little over three hours
last night, and I'm not able to concentrate on anything right now. I
was just getting ready to post a message that I would be off the group
for a few days to a week, to see if I can help her family. My email is
good, so you can contact me off group. I should be in better shape by
Tuesday and more than happy to take a look at it. I may even have a
spare motherboard that would support the card. Email me and give me the
details, I probably won't be back on the group before Monday or Tuesday.

To everyone else, this is the second disabled freind who has died in
the last couple months. I wasn't able to do anything to help the first,
because they can't locate a next of kin. She had a sister, but wouldn't
talk about her or even tell where her sister lived. In this case, her
yuongest son is disabled and she was all he had.
