Kernel microcode errors in messages file

Hi

I have fedora Linuix installed on Intel P4 single processor machine. Today I got the following message in /var/log/messages file:

Sep 28 17:24:57 slate kernel: IA-32 Microcode Update Driver: v1.13
Sep 28 17:24:57 kernel: microcode: No suitable data for cpu 0

Can any body help to explain and resolve this problem.

Thanks

this is done at boot time, i think the script is located in /etc/init.d/microcode.

as you might know, it is possible to update the microcode of your cpu to get rid of small bugs. this is a handy feature, as it saves cost for intel because they don't have to adjust their production process every time they find a bug.

so, linux allows you to load this microcode cpu update when you boot, using the above startup script. i recommend taking a look at the script for more info.
