hey, my motherboard does allow dual bios, but im wondering what is it used for?? In my manual it gives intsructions on updating bios with dual bios, and also ones with single bios.

I always follow the procedure for the single bios update although my motherboard says "dual bios"


kinda just confused on the issue
 
your board has 2 identical bios chips on it. That's why there are two different ways of updating the bios. You need to update BOTH chips to the latest BIOS ideally.

What this protects agains is if you get a bad bios flash, you can copy your BIOS from the "backup" BIOS to get your computer running again.
 
yea i updated the backup bios.

But after it got done reading the file from the disk it said

Checksum EB00. I went with it anyway just because its the backup, and when it was done it said PASS.

But when I go to update my main bios i get the same error, except I dont accept it because I dont want to take any chances.

What Can I do to fix this?
 
Usually if there is an error it will say error.

If it is only saying checksum EB00 but not saying error, it is more then likely fine and just telling you what the checksum value is.

PASS means that the checksum was fine, and it will do the flash or has done the flash.

In my experience anyways.
