Bios checksum error

[bdf24]

I just started getting this every now and then at boot up. It says:

Award bios boot block
Bios checksum error
checking media in floppy drive a.

what does this error mean?

I believe that checksums are used as an easy way to ascertain if a program is working right, or was installed right. Program "a" should have "x" amount of bytes. If the byte count is right, the program is working, or was installed correctly. I may be wrong about this, btw. Checksums may be a different thing entirely!

I suggest going to Asus's Web site. Sometimes it's easier to get on their http://www.asus.com.tw site if their US site is jammed. Read everything they have to say about the Bios Rev. you are using. This requires some digging. For instance, I finally did this after flashing my Bios twice, then reflashing it back to the older saved Rev., because I got a checksum error at the end of the flash process. It turned out that the checksum error was "supposed" to be there. It was a harmless bug.

Your problem seems to be different. You may want to flash to an older, saved Bios. Or, DL the new one and reflash.

I got lucky!

I tried reflashing my bios to see if it would get rid of that error. The error would only come when I would restart my pc. Not on a cold boot.

Well when I reflashed my bios, my pc froze in the begining of the write process! OH ****! I thought. I restarted the pc, and just as I thought no boot. Got a Boot block bios rom checksum error. I had no bios! It got erased! It kept checking the a:/ drive for a bootable disk. So I figured if I got the awdflash and the bios update on a disk all would be well. Fat chance!

I tried reflashing the bios and kept getting an error "unkown flash type". WTF! I tried about 15 different bios updates and some would flash but I would get write fails and some would get the error above. Then I tried the very first bios version from the original release of the board. Well it flashed it and gave me some write fails. restarted the pc and now I lost my video as well!

Well I'm thinking my bios chip is junk. Well after around 3 hours of downloading bios updates from another computer, putting them on floppy's and trying to reflash my bios I finaly found one that worked. What a pain in the ass. I had to put a autoexec.bat on the floppy now cause I had no video so it would auto flash it. All of a sudden I saw the pc reboot and heard that all so wonderfull single beep to let you know everything is ok. WHOO HOO! Well I'm just glad I didnt have to buy a new board or try and get abit to send me a new bios chip.

I cant believe that happened though! I have updated bios's many times and never had one fail.

P.S the error is gone now when I restart my pc hehe!

What did you have to include in the autoexec.bat?

[bdf24]

all you have to do is type

A:\awdflash name of bios update

Like for example this is exactly what I typed for mine.

A:\awdfash beh_po.bin

Then when your pc boots off of your floppy it will run the flash utility automatically instead of having to type it in manually.

(btw, i realise this is an old post) A checksum error almost always means mobo battery problems. If you replace the battery and it still gives you that error, then you can blame the mobo. Just try a new battery and see what happens. The first time you boot with the new battery you will see that, but the next time you shouldn't.

ditto on this .. had the same problem on my 2 yrs old abit board, changed the battery and it ran okay (until I sell it :) )
