cmos checksum error press F1 to enter Bios F2 to install default bios settings

cgator · 11-24-2005, 09:24 AM

motherboard gigabyte GA-7ZXE
CPU duron 950 mhz
HDD Western Digital 40 gb Caviar
256 mb of ram
OS win2k pro
When the system is first booting i am getting a checksum error press F1 to enter bios F2 to load default bios settings. The problem is that the bios does not seem to reconize the keyboard because when I hit F2 to load the default settings it will not proceed in the boot or F1 to enter the bios settings. I am going to swap the battery but, I do not think this is the issue that is causing the boot to stop at the checksum error, not getting bad checksum which would lead me to beleive the battery is dead. one other thing that I notice is the nvram does not show that it is ok. The memory is loading showing the correct amount.

My question is will the nvram cause the system to freeze at the checksum error.

Try replacing the CMOS battery. Replacement battery DL2032 or CR2032.

If the keyboard is wireless, and the transmitter plugs into a USB port, then you need to enable usb keyboard settings in the BIOS I think. Obviously you will need a non wireless keyboard to do this.

all replies above are very good advice / try those first >>> if they dont work then try a bios update >>> before you update your bios get a brief how to in here >>>> the DOS utility is the most reliable as long as you perform a few small simple steps first / read your mobo manual and review the DOS utility version
