How come I cannot burn my BIOS ISO update to a CD?

I’m in the process of upgrading my entire computer. But the first thing I need to do is update my BIOS.

I’ve downloaded the latest BIOS from the manufacturers website.

As I do not have a floppy disk I have converted the manufacturers BIOS into an ISO format.

When trying to burn the ISO file to a CD-R disk I run into all different kinds of errors. Usually the software either falsely states that the CD has been successfully burned, or the CD automatically ejects prematurely, or it doesn’t eject and the software tells me that the burn was not successful.

I have gone through 6 different fresh, untouched CD-R CDs.

I have tried using 4 different ISO burning softwares. Alcohol 120, magic iso, image burn, and Nero.

I have also even tried simply copying and pasting the ISO file into the CD.

My hardware is capable of burning other files onto CDs that are not ISO. But I need to burn with an ISO format in order to make a bootable disk in order to flash my BIOS.

Any ideas how I can burn the BIOS ISO file onto the CD-R CD?

    The reason you’ve having a problem is because you’ve tried to convert the manufacturer’s BIOS into an ISO format.

    What is the make and model of the motherboard you’re trying to run the update on?


    As stated in the OP, the motherboard is an Abit AN-M2 motherboard.

    Thanks so much for the help. =)

    I did also forget to mention, I tried downloading the BIOS “as is” from the manufacturer onto the CD. It did not work.

    I unzipped it, left all of its elements in its folder, and copied it to the CD.

    When trying to boot from this format, I met with failure.

    After researching why my attempt failed, I learned that I needed to make the boot CD read like a boot floppy disk. Which requires me to make an ISO format in order to achieve this. Is this conclusion mistaken?


    One last thing:

    This is the manufacturers instructions for flashing my BIOS.

    I’m stuck on step 5 since I don’t have a floppy disk.

    Picked as best answer

    You’ll need to create a bootable CD, using a software program that supports creating these. Creating an ISO image first isn’t required.

    See this page for instructions, as well as some files you’ll need to make the CD bootable.

    Note that instead of copying the .exe and readme file like in these instructions you’ll need to copy the new BIOS and Abits flash update utility.
