Yeah I was downloading them form the ASrock website.
I'm not sure what you mean for update method. Can you explain me a little more?
Check out the link I posted. There are 3 different P1.5 downloads. (Window, DOS and Instant Flash.)
I have never updated an ASRock, but it seems that they can be updated three different ways.
You need to read up on your board and decide which method you want to use to update your BIOS, then download the update that matches your method.
