Older Intel CPU's Matrix Code (PIII)

Has anyone successfully scanned the 2D Matrix on PIII-era CPU's? On P4's and up, I have success, revealing the ATPO of the CPU using a QR Code Reader app.

 

On my 400MHz Celeron SL3A2, 1GHz PIII (Coppermine) SL52R, and both 866 MHz PIII Xeon SL3WW's, I cannot read the matrix.

 

Any tips to read these?
