CMOS problem

By Deltaboy ·
I have a digital High Note CS450, when I try to boot into Windows95 I get the error, CMOS CHECKSUM INVALID -RUN SETUP, it does the memory check and then <FN-F3> to enter SETUP, I can't enter setup. Then Press F1 to continue, it prompts me for boot floppy, I have replaced CMOS battery and rebooted with same result. I can't get into BIOS. What next? I have run set up, and reinstalled operating system, but still can't boot into Win95, help???

I suspect you might have to perform a hardware CMOS reset to resolve this problem. You'd have to contact a Hardware Support Center for your particular model of Notebook, to help you perform this action if you don't already know how to.

However, forward to me the following details that might help me help you, as it might turn out to be another problem.

a) What actually happens when you press F3 key to try and run your CMOS configuration utility (i.e. any messages, or errors)

b) Boot from A (Floppy Drive) and check for the current Date & Time. Is the date current?


c) Can I assume you are accessing your harddisk to install your Win95 after booting from A (Floppy Drive)?

Most systems have a CMOS discharge jumper or DIP switch which will enable you to clear the CMOS. If none is present, you can usually discharge by doing the following:

1. Remove the CMOS battery
2. use your screwdriver to short across the positive and negative terminals of the battery jack (if the battery has a connector, you may need to make a jumper wire).
3. Leave the battery out and power up the system.
4. Try to enter the BIOS.
5. Power off the system and reinstall the battery.
6. Turn the system back on and see what happens. This process usally works.

Once you get into the BIOS you want to look for a reset BIOS data and restore system defaults. You may also have to redetect your HD depending on the system.

If you have replaced the battery already finding the jumper to clear the CMOS will not help you.

It's FLASH time, pal!

Download the latest version of your BIOS and the FLASH utility, then use a bootable diskette and FLASH that puppy!!!

Goodluck!
