cpupdate : Unsupported version for Intel CPU?

[Ruben]

Hi Stefan,


Is this tool intended to be compatible with all intel CPU's or is it
just for a specific subset of Intel CPU's (or subset  perhaps of
microcode images)?

The reason I'm asking is because I've just given your tool a try and got
an "error" message (see below). I have not tried using the traditional
tools yet (devcpu).

Any feedback appreciated!


Kind regards,


Ruben
