When I replace the CMOS battery in my Dell desktop will my XP(MCE)
recover its settings on its own or will I have to provide all those
settings myself?
There is a DOS program (CMOSRAM2) that copies and restores all those
settings automatically for Win98. Is there such a program for XP?
Thanks.

Your CMOS or BIOS settings are completely independent from the operating
system. So XP will have no bearing in changing the CMOS settings.
Most programs that save CMOS Settings, and I'd suspect CMOSRAM2 would be
the
same, are run from a boot floppy. You start the computer with the floppy
and
run the CMOS save app to create a copy of the settings on the floppy.
After
you change batteries you run the floppy again and restore the settings.

Yes, that what I was asking about. Do you know of such a program that
will work on XP?
When I remove the battery to change it, the computer will be totally
without power. I assume that all the bios settings are in volatile
memory and will be lost when the old battery is removed. That's just
an assumption; if the bios settings are stored in permanent memory
they will be okay. I was told that some systems have a capacitor that
provides a charge for the bios memory for a short time while the
battery is being changed, but who knows...
I don't mind setting the time manually, but I don't want to have to
reset all that bios stuff if there is an application that will do it
for me.
Thanks. Jackson
I think you missed my point. Because you will boot the program that saves
your CMOS settings from a floppy disk you don't need one that works with
XP.
XP isn't even going to be loaded because the floppy will load before the
hard drive. Just boot your CMOSRAM32 floppy and save the CMOS settings.
Okay, I see your point and it makes sense. I will give it a dry run
and check out what it copies as the BIOS. But my present 64-bit twin
CPU system is very different from the 98 system that I had before and
I am not sure that CMOSRAM32 knows where the stuff is kept. I googled
for the old file, but could not find any reference that it could be
used on machines that run XP.
I guess that if the "retrieve" part of the program copies stuff to a
floppy from my HD, that the "restore" part of the program would copy
it back to the same memory location.
Thanks for your help.
I don't know how to make this any clearer but it doesn't matter what OS you
have installed as the CMOSRAM32 program runs independently from the OS. In
fact you could completely remove the hard drive and it should still be able
to copy and save your CMOS setting to the floppy. Don't try saving the file
to the hard drive. Just save it to the floppy. Or get out a digital camera
and run the BIOS screens snapping a picture of each one and don't bother
with the CMOSRAM32 floppy.
