**GC101/102/103 12/16MHz PC/AT Compatible Chip Set + EMS 4.0   c:Jul89
***Notes:...
***Info:
The GC103 is a companion chip  to the GC101/102 AT chip set. Replacing
the GC102  in its Address Buffer  mode, this chip adds  logic to fully
implement LIM, EMS  4.0.  This device expands the  capabilities of the
GC101/102  chip set.   It adds  support for  up to  8MB of  memory and
Shadow RAM for systems  and video BIOS. The register-intensive design,
combined  with the  use of  system memory,  offers extremely  high EMS
throughput compared with EMS  systems using fewer mapping registers or
expansion  memory. The  GC103 contains  a chip  mapping  register that
allows  EMS  to operate  at  full  system  speed without  adding  wait
states. With 2 sets of  32 EMS registers context switching in hardware
as well as software is supported.

The GC103 provides address buffering  for the expansion bus, local I/O
bus, and the  system board DRAM.  Address ,  DMA, and Refresh controls
are  included  in the  GC103.  The  chip  integrates additional  logic
previously implemented discretely in  the GC101/102 board design. This
device is packaged in a 160 pin quad flatpack.
