Hi,
I have one Pentium Pro motherboard, which uses a Dallas RTC 14187 realtime clock chip (24-pin DIP package), with its own built-in lithium battery.
When recently the battery inside the chip went dead, my system refused to boot because the Bios enters a loop saying "system battery is dead, replace" and restarts the boot process, going back to the ram test.
Now... thinking a bit about this... it SUCKS because:
a) Nobody can't warranty that Dallas Semiconductor will be around forever b) what if they some day they drop the DS14287 ???.
My question: Is there a way to isolate the battery from the RTC chip, so I can place an external watch-type battery without having to purchase a new RTC chip from Dallas every time the battery dies?.
as I said, the chip is a DS14287.
Thanks Willy
