***Info:
****General:...
****82C681 (EBC) EISA Bus Controller:
The EISA Bus Controller (EBC)  is a 160-pin PFP (Plastic Flat Package)
device capable of operation in both 386 and 486 mode. It generates the
EISA  bus  clock (BCLK)  as  well as  the  keyboard  clock while  also
providing board level and  CPU/Coprocessor reset signals. In addition,
the EBC controls  the interface between the EISA bus  and the Host bus
and arbitrates  between Host/  EISA/ISA Masters, DMA  controllers, and
Refresh requests  for the EISA bus.  It directs the  steering logic of
the  DBC   and  the  ISP   and  provides  latch/buffer   controls  for
address/data byte lane translation/swapping. Additionally, it provides
the address  translation between masters and slaves  for addresses A20
and A[1:0].
