**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.
