Socket 754 BIOS

[simwiz]

Hi, I'm new to the community but along time reader. I thought I'd post a quick message of pain.

Last weekend I switched my P.C on to be prompted with the checksum error. I realised this basically means the bios defaulted its settings and so my dual booting didnt work etc.

I changed the CMOS battery and again the BIOS resulted in a checksum error. I then changed my bios setting to how i had them before the problem occured. I was then prompted with the boot menu but for some reason my keyboard didnt work. SO i couldnt pick the correct OS at boot time.

arghhh, The keyboard does work initially because I had to enter the bios to change the harddisk/ floppy disk settings.

I then left the system from friday to sunday. Now the check sum error is back and will not boot, so basically looping my problem again.

If any one has any ideas then please post,
I have flashed the BIOS, changed the CMOS Battery and now i'm considering updating the BIOS also. Is there a way of booting the BIOS flash files from CD? without creating a floopy disk etc.

thanks for your support!

there will be a jumper to clear your bios. make sure itis set correctly. check your motherboard manual to get the correct setting

Thanks for the reply, I've tried that, I have cleared it a couple of times. But no look, may be a new BIOS chip? but i doubt thats worth while

It does sound as if the BIOS is corrupted - and clearing the CMOS (which 'only' contains some initial configuration serttings will not help.

Reflashing the BIOS might help - but you aren't going to be able to do that unless you can get the machine to boot - reflashing usually involves booting from a f;loppy into a DOS environment and running a utility that copies the BIOS image to teh bios itself.

If the BIOS is removeable, then you may be able to get a new bios, ready flashed, either from the mfr or from

bios-repair.co.uk | BIOS Repair, BIOS Replacement

Depending on the make (and age) of the mobo you might be able to enter a reflash mode at start up (Asus mobos offer this) but if the BIOS is corrupt, that may not work. Your mobo manual will give details.

BTW - welcome to Hexus!

Thanks for the reply! My system is booting now but the BIOS seems to be holding its settings for the time being. I guess its a matter of time before I receive a cmoz check sum error and back to default settings.

Hopefully it will hold out untill I get a Nehalem board and processor Unless AMD have something up their sleeve?
