via chipsets

after scanning epox`s website.
something caught my attenton.
the via appollo pro(a) plus , 266,266t
are the same north and south bridges as the
kt-133(a),kt-266(a)
nb)c686a or 694(a)
sb c686b
if i am not mistaken those are not new via chips but
rebadged via appollo chips.
if i am right , they sure are devious sob`s

That seems really odd. I hope that its just a silly mistake or something.

They are not all the same chipsets. The southbridge is common among many of the chipsets - these are usually compatible with just about any other northbridge; they just control the PCI bus and hard drive controller and whatnot.

Northbridges are specific to CPU types. I looked up VIA's actual model numbers for these northbridges in question.

KT266A - VT8366A
KT133A - VT8363A
Apollo Pro 266 - VT8633 (note, 8633, not 8366...)
Apollo Pro 266T - VT8653
older Apollo Pro 133s are all VT82C69x series chips, modified for different purposes.
