Without doing a conformation check I am sure that the 1019 to 1023 are for the
P4C800XXX and I am pretty confident that due to the fact that the P4C uses a different chipset it wouldn't work. I wouldn't even attempt to flash my bios to another model for chance of turning my mobo into a paperweight. I will look and see if there are any other Beta bios's about for you
.
Edit: while doing a check i came across this article that may help some, have a look at this page and the page after it
