**VT82C486/2/3 "GMC chipset"            [no datasheet, some info]    ?
***Notes:...
***Info:
8) The VIA GMC chipset  (VIA:  1106/4358) (5/18/96)
  --------------------

This  chipset  includes  the  VIA VT82C486A-F  with  a  built-in  8042
keyboard controller and  a VIA VT82C505-D chipset for the  VESA to PCI
bridge.  Specifically, the chips are as follows:

82C486A - cache/memory controller + VLB to ISA bridge
82C482 - VLB to ISA bridge (why there are two I'm not sure)
82C483 - DRAM controller
VT82C505 PCI to VLB bridge

A board using this chipset has been unstable (even under DOS/Win), and
did not work  with an Adaptec 2940 SCSI controller  under OS/2 at all.
Boards based  on this chipset  are therefore  to be avoided.   I have,
however, had  one report of success  from someone using revision  G of
this chipset, so it could be that the new revision fixes problems with
older  rev's.  Designers  with  whom I've  corresponded indicate  that
improperly designed  boards which use  this chipset may  have unstable
caches.  In  addition, the  cache controller reads  the data  into the
cache SRAMs first, then into  the CPU, increasing latency and reducing
throughput.
