[AboutSystem] Pentium is detected as Core i5

[dsjonny]

On my brother's laptop I still have problem with the Intel Pentium CPU detection. It detects as Intel Core i5, but it is Intel Pentium:

I use the official R1 Alpha 4.1.

Still exists in 45341.

The Pentium P6100 is a mobile chipset based on the i5 architecture. As such i'm inclined to mark this one as invalid. We can't possibly keep track of all of the crazy CPU branding these days (relabled this, rebadged that). CPUs don't offer a consistant way to detect the branding, only the generation based on CPUID.

side note, this detection happens here: ​http://cgit.haiku-os.org/haiku/tree/headers/private/shared/cpu_type.h

if you have this machine still with Haiku, go ahead and run sysinfo on an image post-hrev46659 it will dump out some detection information, if it is identifying itself as an i5 there isn't much we can do unless we start building a huge database of Intel CPU brand ID's "P6100, etc"

I think we should remove all newer Intel detection code besides the parsing of the name.
