**A note on VESA support of 486 chipsets.
Many chipsets state that they support VESA local bus. In some cases
these actually implement VLB somewhat like PCI, where it is entirly
decoupled from the CPU bus. Chipsets that do not state they work with
VLB, may be found on motherboards that contain VLB slots. VLB
is *basically* The 486 CPU pinout in a slot form. Unless these
m/boards contain some additional chips, there VLB implementation is
directly coupled to the CPU.
