A new utility to test for PAT enabled

[oldfart]

Saw it on ABX. ctlaw (ftp://ftp.heise.de/pub/ct/ctsi/ctiaw.zip) will test for PAT enabled among other things. It seems to have one bug that I can see. It calculates mem speed from stock FSB instead of actual. Here is mine from my IC7 running a 5:4 ratio. Like CPUz 1.18c, it shows that PAT IS working.

Very nice....... :-)
