Has anyone had a CPU-ID signature report a "1" instead of a "0" for the CPU below, I'm trying to get my CPU to report a 1 instead of a 0 as its an overdrive (1) and not a standard (0)

486 Overdrive CPU:
DX2ODPR66
C4460408
SZ935 V4.0
Intel 89 92

My CPU-ID signature is 000435 and the information online about this CPU says its "435" or "0435" but I remember some time ago on YouTube someone said they were able to enable something in Dos with a program to make the third 0 a 1 and it helped his system to have better performance, in his video he showed benchmarks to show the difference - hay Phil, (Phils Computer Lab) was this one of your videos?
