Hello!
Where can I find the last microcodes for P4 CPUs? I need them for 423-pin and 478-pin socket CPUs. Does anybody have the last pep.dat file (CPU microcode database) from Intel?

the info you're asking for is only available to Intel channel partners under an NDA...

Yes, I know that it is not for public use.
I found another files, but they are too old too (2002 year) http://www.ixbt.com/cpu/utils/pep.zip http://www.ixbt.com/cpu/utils/checkup6.zip
Also it is possible to extract microcodes from system file "update.sys". Or from bios with the help of Cbrom.

I did with ctmc, I took the update.sys from the latest build of
Windows2003 server Sp1 & extracted the microcodes,
then remade 1 large microcode file with ctmc for use with
both the intel update utility & the acer one...
The microcode package can be Downloaded here.

I was recently learning about all this.

What is the purpose of putting the microcodes in the BIOS, when you can add them by using a different update.sys?

Thanks.

You cannot always use an update.sys

Thanks edwin for that very astute reply. :wink:

Can you elaborate why?

Again, I know nothing about this.

Thanks.
