Bios HDD configurations not saved

By Casemaker ·
Hi,
I am running a pc with W98SE and the BIOS (American Megatrends 12/26/2001) will not save the HDD configuration info. I changed the cmos battery and still the same. When it boots it will not find the HDD, I go into setup and choose auto find and hit enter it searches and then comes back and auto find has changed to user with the HDD settings. I save the configuration and it boots into windows once. It will restart and no problem but not a cold boot. Is there a possibilty that the cmos has gone bad?
Thanks

You may want to try to flash the BIOS. If that doesn't fix the problem, load a boot-manager for the drive that will boot the drive instead of the BIOS.

Another thing you can do is write down the information and manually plug the numbers in (the cylinders, heads, et al.

Does the real-time clock keep the correct time?

If so, it is not a power issue.

If the RTC does not keep the correct time, verify that the battery is actually making solid contact to the socket.
(You can clean both the battery and the contacts with a pencil eraser.)

If this is an ATX system, the battery does not come into play unless the AC line power to the PC is turned off.

Check the clear CMOS jumper.
Even if it is just dirty, it could be part of the problem.

As to the CMOS memory itself, it is possible that it has failed.
Are any other BIOS settings changing?
Do you ever get CMOS checksum errors?
If the answer to the above is no, I would expect IDE controller problems before CMOS issues.

If the drive data is all that you lose, I would try installing a PCI IDE controller card.
For around $ 20 - 30 (US) you recover your system and likely have a better IDE controller.

Also verify that you installed the battery with the correct polarity orientation. Does the time remain accurate when you reboot? Check it in the bios setup. A battery problem, even though you replaced it, is the likly problem. One other thing, remove the bios CAREFULLY and reinsert it CAREFULLY!! Make sure it is firmly seated. The pin connected to the battery back-up my not be making good contact, or you may even have a broken land (the printed foil lines)going from the battery to the cmos.
