trying to update the BIOS when I do this this is how it occures

I downloaded new file ASUSUPDT60201.ZIP . ASUS Update V6.02.01 Installation Program for Windows 95/98/ME/NT40/2000/XP/2003..and then install. so I run this program which is called Asusupdate.This program is for updating your bois via the internet.so program runs It opens It connects to the asus web site I get message Select BIOS version it shows 2
K8N 1004-02 BETA [26 11 2004 ]
K8N 1003 Final [03 11 2004 } **** I choose this one *****
then I press next it downloads a file
then I get message

I press Flash
I Then get a status bar shows
Erases rom 100%
Flashes rom 100%
verifys rom 100%
Then get message Need to reboot system for changes to take effect.
I reboot
Then I get message
Auto detecting Drives goes through all of the drives then says ok
then says
CMOS checksum bad
Press F1 to run setup
Press F2 to load defalt values and continue

If I press F1 it takes me into the bois screen
If I press F2 it starts up windows.
with no bios change still has original BIOS version # 08.00.09 <10 04 04 >

I also tried the alt F2 method using a floppy.I get all the way to the end goes through all of the steps erases flashes and verifys all 100% then the system restarts and I get same error

CMOS checksum bad
Press F1 to run setup
Press F2 to load defalt values and continue

still no bios change

I would suggest you get another copy of the same thing but from another server or go to the bios just before it
Sounds like there is a glitch in that particular file version

[nascards17]

wow that was a fast answer I like that!
so what you are saying is use a diffrent asus mirror site and download this same bios file and try it again.

[Ferrit]

Yes either that or go for one just before the one you have 1 older rev if nessecary

I agree with Ferrit. Download another version.

good to be part of your forum was using another. but was not getting the help I needed or the help took to long I am sometimes impatient. once again thanks for the quick response. also my mb temp is 80F and my cpu is 86F does this sound about right to you.

ok now I have a real intresting question my bios says bios 08.00.09 <10 04 04 >
I run dxdiag it says BIOS: BIOS Date: 10/04/04 14:10:12 Ver: 08.00.09 then I check system information it is telling me bios version date 1003.009 <10 04 2004> my question is what am I truley runing for a bios and is this the reason I get cmos checksum bad error.
