Cmos checksum bad when updating asus a8v deluxe
Recently I did a clean install of windows XP on my PC, everything goes smooth and no errors. Thanks & good luck Cmos equals continuous metal oxide semiconductor. I've been doing some reformat and clean install before and I never encounter this problem before its my 1st time to have this problem..But after a day I use it and shut it down for an hour and when I return and turn my PC again this problem comes out... It is the small disk battery found on your motherboard. (it's probably this) = but sad to say it doesn't fix the problem still there.... T_T As dbarker suggested please post as much detail as requested.
As to the OP's problem, maybe clearing cmos through a jumper on the motherboard might resolve the checksum error.I have tried the following: I have unplugged all devices from the mb except for one stick of ram and the proc.I have removed the cmos battery and tested it with a vom. I have unplugged the power supply and removed the battery for over an hour, completed the CMOS reset procedure and reinserted the battery, plugged the power supply back in.when that screen appears my keyboard wont function.... Check out section 1.11 in dbarker's manual link above. And make sure the disc is in the drive before you start the computer.It appears that the computer is looking for a disc with the BIOS file on it. Since you lost the support CD which contains the original BIOS file, uownload the latest BIOS update from Asus (previously linked) burn it to CD or copy it to floppy if you have one.
If this doesn't help, maybe reprogramming the BIOS through BIOS update will do the trick.
