: Thanx Henry.

: My hardware configuration is:
: Pentium 120
: Socket 7
: PIC and ISA bus
: 4 EDO RAM and 2 SDRAM (PC66)
: The CMOS chip is : RALLAS DS12887A Real Time Clock
: the chip has a embeded battery (sitting on the top of the chip inside) and is pluged into a socket.

: Youli
: : : Env: Pentium 120, 2 IDEs. Win98.

: : : I have a problem to keep the BIOS settings (maybe due to a battery failure), so every time the CMOS setting goes to default seeings.
: : : The "default" settings only have the first master HD be "AUTO". Thus I can only use one HD.
: : : How can I add a second HD in this situation withou changing the battery-embeded COMS chip?
: : : (Currently the second HD is connected as first slave and can be detedted by COMS, but it backs to default as soon as power up)
: :
: :
: : Please post your hardware configuration and the number of the module (Real Time CLock) with the battery inside - DO NOT TRY to replace the battery or module (yet) I have links to useful info if you have what I think you have. The module should be in a socket but there is probably no way to connect an external battery without DELICATE surgery.

: : BE CAREFUL.

: : Henry


I have not heard of anyone successfully replacing the battery in a DS12887A - BUT you CAN get a replacement module (with a fresh battery) from:
http://store.firmware.com/cgi-bin/mfi/DS12887A.html

If the battery is plugged into a socket you may find a good electronic Tech who has the right tools to get the battery out without breaking anything. It is most likely a 3.0V battery but probably reads pretty low now.

Good Luck,
Henry
